Salt Bridges

[Abby Lam 3F]

Hi,
Could someone please explain the purpose of a salt bridge?
Thank you!

[Saumya Tawakley 1E]

I believe salt bridges allow the flow of spectator ions in the reaction so there isn't an accumulation of charge on either side (which would cause the reaction to stop). Essentially salt bridges are necessary to keep neutrality between the oxidation and reduction half-cells.

[SamanthaTolentino 3D]

The salt bridge is there to prevent the ions from accumulating, helping to maintain the electrical neutrality.

[Cooper_Geralds_3B]

a salt bridge, also known as an ion bridge is used to connect the oxidation and reduction half-cells of a galvanic/ voltaic cell, and its purpose is to act as source of spectator ions that can migrate into each of the half cells to preserve neutrality.

[EmilyGillen_1A]

^^ A salt bridge is designed to make sure the ionization of each solution in a galvanic cell stays neutral. A salt bridge allows for the flow of ions NOT involved in the observed reaction ("spectator ions") so each side can remain neutral (the salt bridge does not affecting the main reaction).

[Jason Knight - 1F]

The purpose of the salt bridge is to allow the free flow of ions from one cell to another without mass accumulation. Without the salt bridge, positive and negative charges would build up causing a disturbance in the reaction.

[Kayle Lim 2C]

Salt bridges are important for the flow and transfer of ions within cells while maintaining neutrality. This is important for control and prevents charges on either side of the bridge from building up. Salt bridges allow for free flow and essentially act as a neutral balance.

[Melis Kasaba 2B]

A salt bridge is a device used to connect the oxidation & reduction half cells in a galvanic cell to allow the ions to flow between them. It also helps provide spectator ions that can migrate into both of the half cells to maintain electrical neutrality. Electrons flow from the anode to the cathode through the salt bridge.

[Alen Huang 2G]

I think the salt bridge contains spectator ions that would cancel out the charges on each side of the galvanic cell in order to allow electron flow to occur.

[Katie Nye 2F]

Without the salt bridge the reaction would be disturbed because it maintains the flow of ions between the solutions.

[austin-3b]

It helps maintain neutrality I believe.

[Brianna Chen 3F]

Salt bridges are used the diffuse the build up of negative charge, basically offsetting the change in potential.

[George Hernandez 3I]

As the charge begins to build up, the cathode gets more negative and repulsion starts to take place when more electrons attempt to enter. By using a salt bridge, some ions can move from the cathode to the anode and allow for more electrons to be transferred.

[Brenda Silva 1B]

Salt bridges are needed to maintain neutrality and allow cells to flow freely without having mass accumulation.

[Sabrina Galvan 3J]

The salt bridge helps the cells maintain a neutral charge as electrons move from one-half cell to another! This helps the reaction continue without disruption or repulsion from the negative charge of the electrons.

[SLai_1I]

The salt bridge is implemented so that positive and negative charges don't build up too heavily on either side. The bridge provides charges ions to balance out the anode and cathode sides.

[Alexandra Ahlschlager 1L]

The salt bridge prevents a buildup of charge on one side of the galvanic cell and essentially maintains a neutral environment to allow the reaction to continue.

[Zainab Jamali 1H]

The salt bridge prevents ion build-up on either side of the galvanic cell and helps maintain a neutral charge as electrons flow between the two sides.

[Margaret Xu 3C]

Salt bridges and porous discs keep the solution neutral so that electron flow is continuous.

[LarisaAssadourian2K]

Hello! I like to think of a salt bridge as something that closes the circuits of the cell so that the electrons can flow properly. This keeps both sides neutral by letting the cations go to the cathode and the anions go to the anode.

[Sharon Kim 2A]

The purpose of a salt bridge is to keep the solutions neutral so there is no buildup of charges on one side. This can also be done with a porous disk, where cations and anions are able to pass through. Keeping a neutral solutions will help keep the electrons flowing.

[Evonne Hsu 1J]

The purpose of the salt bridge is to prevent the ions from building up and help to maintain neutrality.

[Sreeram Kurada 3H]

The Salt bridge's function is to equalize the charges (ions) on both the cathode and anode side of the reaction.

[sophia kosturos 2B]

the salt bridge is there to prevent build-ups on either side of the galvanic cell because this could compromise the neutrality of the solution and prevent electron flow. The salt bridge is necessary to maintain the flow of electrons.

[Neel Sharma 3F]

The purpose of a galvanic cell is to convert chemical energy to electric energy. However, the chemical energy that is derived from charge differential etc. can be exhausted if its not replenished by the cations/anions present in the salt bridge. Hope this helps!

[Brian_Wu_3B]

Salt bridges are there to help maintain neutrality in order to keep the reaction going.

[Shana Patel 1C]

A salt bridge is a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell, a type of electrochemical cell. It maintains electrical neutrality within the internal circuit.

[Nick P 3D]

Salt bridges essentially allow ions to flow back and forth, preventing an accumulation on one side which would result in a charge and disrupt the processes at work.

[Bella Bursulaya 3G]

If there was no salt bridge, the charges from the reductions and oxidations build up (positive on the side of the anode and negative on the side of the cathode) and therefore the reduction potential is much smaller. The larger the difference in charges, the easier it is to transfer electrons. Therefore, if charges can be neutralized the transfer of electrons can continue.

[Devan Nathu - 2H]

salt bridges are simply there to prevent ions from accumulating. This helps with neutrality.

[Ziyan Peng 3A]

Dr. Lavelle mentioned during Wednesday W7's lecture that the salt bridge is where anions leave and e- enter, so to prevent e- transfer from one beaker to another from halting because of charge buildup.

[Britney Tran IJ]

the salt bridge acts as prevention against ion accumulation

[Jerry_T]

Salt bridges prevent ions from accumulating by allowing electron flow from the anode to the cathode (i.e. it maintains neutrality).

[Isabella Cortes 2H]

Salt bridges make sure that charges do not build up on either beaker by allowing ions to move to the side that it will be attracted to due to opposing charges. They will keep the solutions in the beaker neutral

[Gabe_Ek 1G]

The purpose of salt bridges is not to of move electrons from the electrolyte, but rather maintain the charge balance because the electrons are moving from one half cell to the other.

[Isabel_Eslabon_2G]

Salt bridges help keep electrons moving from the anode to the cathode. Spectator ions move from one solution to another via the salt bridge. This prevents the charge from evening out across both sides of the cell, which would prevent electrons from continuously flowing in one direction.

[Arnav Saud 2C]

Salt bridges help maintain the neutrality of the charges in the system.

[joshtully]

The salt bridge is used to maintain neutrality.

[Arnav Saud 2C]

Salt bridges allows the neutrality of the cell to be maintained by allowing electron flow through the cell.

[Muskaan Abdul-Sattar]

Salt bridges help to prevent the buildup of charges by allowing for the transfer of electrons.

[Levon Grigoryan]

The purpose of the salt bridge is to act as a source of spectator ions that can migrate into each of the half cells to preserve neutrality. Any charge buildup in the solutions of the two half cells is known as a junction potential.

[kristinalaudis3e]

they are necessary to prevent buildup !
