Basic salts
« on: August 11, 2017, 03:11:45 PM »
Hi

I have a question regarding basic salts. I know they are made from a weak acid, but is it possible to make a stronger basic solution by changing the cation?

Would a solution with fx Sodiumacetate have the same pH as potassiumacetat?  :)

Do you know the Bronsted theory? If metal cation reacts with water, what are possible products? Is OH- between them?

Yes i know the Bronsted theory and that the metals in solution are hydrated/OH- in between them.

But what makes a sodium/potassium (or other) salt with samme conjugate base a stronger base that the other?

For the solution to be more basic (assuming the same hydrolyzing anion) you need something to produce more OH-.

Can the cation reacting with water produce any OH- and make the pH higher?
