If the reverse reaction is favoured and it includes a solid as a reactant, the solid concentration is not going to increase as solids and liquids stay constant right?

Question

To determine which solution is most basics given [OH-] / [H30+], you take the -log and you compare it on the pH scale?

a.[H30+] = 10^-2
b.[OH-] = 10^-4
c.[H30+] = 10^-11
d.[OH-] = 10^-13

C. would be the most basic as it gives you the pH of 11. Is this right?

-Also what is a good site for studying hydrolysis of salts deeming them as neutral, acidic or basic?

TIA!

Answer 1

a. Some solid must be present but the concn does not change.

b. yes. a has a pH of 2, b has a pH of 10, c has a pH of 11, and d has a pH of 1 so C is the most basic.

Here are a couple of sites for hydrolysis of salts.
