a. Write an equilibriu equation for a solution containing `CH_(3)COOH` and `CH_(3)COONa`. What effect does `CH_(3)COONa` have on a solution of `CH_(3)COOH`?
b. What reagents should be added to a solution to increase
i. `[CH_(3)COO^(Theta)]` ii. `[overset(o+)NH_(4)]`

Explanation

a. `CH_(3)COOH + H_(2)O hArr CH_(3)COO^(Theta) + H_(3)O^(o+)`.
According to Le Chatelier's principle, `Ch_(3)COONa` shifts the ionisation reaction to the left. `CH_(3)COONa` does not recat with `CH_(3)COOh` to produce other products.
b. i. `CH_(3)COONa` or any soluble acetate but not `CH_(3)COOH`.
ii. `NH_(4)C1` or any soluble ammonium salt but not `NH_(4)OH`.
