Reaction between potassiumhydrogensulfate & potassiumhydroxide

[mcfaker]

Hi,

Is the reaction between potassiumhydrogensulfate & potassiumhydroxide a proton-transfer reaction? If it is, it must also be an acid-base reaction. But the problem is that its not a reaction between an acid & base, but between a salt & a base!


Thanks!

Write formula of potassium hydrogen sulfate and dissociation reaction for the salt.

Just because it happens to be a "salt", it doesn't means it always loses its ability to react with other acid or base. And also, acid and base are relative terms, so don't worry about KHSO₄ being acidic or basic.

Thanks for the help Borek & Agnuke. :)

Yes, the reaction between potassiumhydrogensulfate and potassiumhydroxide can be considered a proton-transfer reaction. This is because potassiumhydrogensulfate can act as an acid, donating a proton to potassiumhydroxide which acts as a base. However, as you mentioned, it is also a reaction between a salt and a base. In this case, the potassiumhydrogensulfate acts as the salt and the potassiumhydroxide acts as the base. The resulting products of the reaction would be potassium sulfate and water. So, while it may not fit into the traditional definition of an acid-base reaction, it can still be classified as a proton-transfer reaction.
