Strong or weak acids/ bases

[AlyssaPeckham1A]

How do you determine if an acid/base is weak or strong?

[Maya Krishnan 3E]

Strong acids produce more protons in a solution than a weak acid, such as Hal, or HBr. Also, weak acids are incompletely ionized in a solution.

Strong bases are completely ionized in water, such as Li2O or NaOH. Also, weak bases are not completely ionized in water

[Kaileigh Yang 2I]

A strong acid also typically has weaker electron affinity because it makes it easier to break off completely into its ions.

[Elana Weingord 1C]

How do you know how well a base will ionize in water if you are just given the chemical formula?

[Chem_Mod]

Strong acids/bases dissociate 100% to produce H+ or OH- and weak acids do not.

You should memorize the strong acids/bases (which there are a few). Anything that is not a strong acid/base is a weak acid/base.

[Shione Nakahara 1F]

Most acids are weak acids that dissociates incompletely. These acids have higher pKa than strong acids which release all there H+ when dissolved in water. Likewise, a weak base is a base that does not ionize fully in water and also has a lower pH compared to strong bases.

[ramayyala1G]

The easiest way to do this is just memorize the 7 strong acids and 8 strong bases. Anything else is weak pretty much. The strong acids are HCl, HBr, HI, HNO3, HClO4, HClO3, H2SO4, H2SeO4. The strong bases are NaOH, KaOH, CsOH, Can(OH)2, Sr(OH)2, RbOH, Ba(OH)2
