A) weakly basic
B) strongly basic
C) weakly acidic
D) strongly acidic
Correct Answer: A
Solution :
\[N{{a}_{2}}C{{O}_{3}}\], on hydrolysis gives a strong base\[(NaOH)\] and a weak acid \[({{H}_{2}}C{{O}_{3}})\]. Hence, the resulting solution will be weakly basic. \[N{{a}_{2}}C{{O}_{3}}+2{{H}_{2}}O\underset{strong}{\mathop{2NaOH}}\,+\underset{weak}{\mathop{{{H}_{2}}C{{O}_{3}}}}\,\]
