Answer:
All three statements are true
Explanation:
Solubility equilibrium of silver acetate:
- If pH is increased then concentration of
increases in solution resulting removal of
by forming
. Hence, according to Le-chatelier principle, equilibrium will shift towards right. So more
will dissolve
- If
is added then concentration of
increases in solution resulting shifting of equilibrium towards left in accordance with Le-chatelier principle. So less
- Insoluble precipitate of AgOH is formed by adding NaOH in solution resulting removal of
Hence all three statements are true
