Homework Statement
State whether the following salts are acidic or basic in solution. Assume all salts given are soluble and 100% ionized in solution
a) KF
The Attempt at a Solution
I have one major question. How can you tell which ion is a spectator ion? because without knowing this both answers are true. The answer in the worksheet is basic. So what am I not understanding?
For example in a):
[tex] KF \rightarrow K^{+} + F^{-}[/tex]
[tex] K^{+} + H_{2}O \rightleftharpoons KOH + H^{+}[/tex](The solutions is acidic - Dissociation)
[tex]F^{-} + H_{2}O \rightleftharpoons HF + OH^{-}[/tex](The solution is basic - Hydrolysis)
If the answer is basic that would mean K+ is a spectator ion ... WHY? and HOW do you know that? How do you figure it out?
