Solution

a)
sodium acetate is the salt formed from sodium hydroxide (a strong base) and acetic acid (a weak acid)
NaOH + CH3COOH ---------> CH3COONa + H2O
(base) (acid)

b)
when an aqueous solution of sodium hydroxide is saturated with carbon dioxide, sodium hydrogen carbonate, NaHCO₃, is formed in solution
CO₂ + 2 NaOH → Na₂CO₃ + H₂O
(base)
Na₂CO₃ + CO₂ + H₂O → 2 NaHCO_{3

c)
Aluminium chloride may be formed by the reaction of
aluminium and Hydrochloric acid
2Al + 6HCl ------>2AlCl3(aq) + 3H2(g)
(acid)}

d)
potasium chloride can be generated by treating potassium hydroxide (a base) with hydrochloric acid:
KOH + HCl → KCl + H₂O
(base) (acid)
