• B. (i) $C{H}_{3}COOH$ (ii) $CuS{O}_4$ (iii)$Ba(OH{)}_2$
• C. (i) $C{H}_{3}COOH$ (ii) $KOH$ (iii)$NaOH$
• D. None of these

Answer 1

Answer: (C)

1. Formic acid is produced by ants and acetic acid is used as anti-wasp agents.
2. In alkali batteries a base is used as an electrolyte which gives hydroxyl ions in solution.
