a Which of the following solutions are acidic? (Select all that apply.) 0.1 M NaCH3CO2 ✓ 0.1 M NaCl 0.1 M CH3CO2H 0.1 M NHÀ 0.1 M Na2CO3 ✓ 0.1 M NHACI b Which of the following solutions are basic? (Select all that apply.) 0.1 M NaCH3CO2 ✓ 0.1 M NaCl X 0.1 M CH3 CO2H ✓ 0.1 M NH3 0.1 M Na, CO, 0.1 M NHACI Which of the following solutions is most acidie? 0.1 M NHACI | 0.1 M CHCOH

Answer 1

Answer a):-

The solutions which are acidic are :-

0.1 M CH_{3​​​​​​​}CO​​​​​​​₂H

0.1 M NH₄Cl

Explanation :-

CH​​​​​​​​​​​​​_{3​​​​​​​}CO​​​​​​​₂H is an acid while , NH₄Cl is an acidic salt (salt derived from the reaction between the weak base, NH₄OH and and strong acid, HCl).

----------------------------------------

Answer b):-

The solutions which are basic are:-

0.1 M NaCH₃CO₂

0.1 M NH₃

0.1 M Na₂CO₃

Explanation:-

NH​​​​​​​₃ (ammonia) is a base. NaCH₃CO₂ and Na₂CO₃ are basic salts.

Answer c):-

The most acidic solution is :

0.1 M CH₃CO₂H
