Protonation & Deprotonation
What is protonation or deprotonation referring to when talking about acids and bases? How do we calculate percent protonation/deprotonation?

Re: Protonation & Deprotonation
When referring to acids and bases protonation is gaining a proton so this usually refers to a base as they are the ones that gain an electron and deprotonation refers to the acid because they are the ones giving up a proton.

Re: Protonation & Deprotonation
To calculate % deprotonation (because this is the most common factor that questions ask for),
1) solve for the x variable in the ICE table
2) put x over the initial concentration (Divide x by initial concentration: x/[R])
3) multiply by 100 to convert that to number to a %
4) that is your % deprotonation
1) solve for the x variable in the ICE table
2) put x over the initial concentration (Divide x by initial concentration: x/[R])
3) multiply by 100 to convert that to number to a %
4) that is your % deprotonation

Re: Protonation & Deprotonation
I think that this is what Lavelle was trying to demonstrate using the Lewis structures in the water example of how pH is decided. Like H3O+ vs OH-, OH- is deprotonated and H3O+ is protonated?

What is the significance of this?
Re: Protonation & Deprotonation
Protonation occurs when a proton is added to an atom, molecule, or ion. Protonation and deprotonation occur in most acid-base reaction. A species' mass and charge change, and its chemical properties are altered when it is either protonated or deprotonated. For example, water can be protonated by sulfuric acid: H2SO4 + H2O ⇌ H3O+ + HSO-4

Re: Protonation & Deprotonation
Protonation occurs when a hydrogen ion is added to a molecule, and deprotonation happens when a molecule loses a proton. Bases are often protonated and acids are usually deprotonated. You calculate % protonation by dividing the product species that has been protonated/deprotonated by its conjugate form on the reactant side, then multiply by 100 to get the percentage.

Re: Protonation & Deprotonation
protonation is the addition of a proton and deprotonation is the removal of a proton. Protonation refers to bases usually and deprotonation to acids.
Re: Protonation & Deprotonation
Protonation for bases mostly and deprotonation for acids. Refers to gaining, losing protons
