Vedclass · Answer

(A) Sodium carbonate $(Na_2CO_3)$ is a salt of a strong base $(NaOH)$ and a weak acid $(H_2CO_3)$.On hydrolysis,it reacts with water as follows:$Na_2CO_3 + 2H_2O 	o 2NaOH + H_2CO_3$The $NaOH$ produced is a strong electrolyte and undergoes complete ionization:$2NaOH 	o 2Na^+ + 2OH^-$Thus,one molecule of $Na_2CO_3$ produces $2$ hydroxide ions $(OH^-)$ upon complete hydrolysis.

The number of hydroxide ions,produced by one molecule of sodium carbonate $(Na_2CO_3)$ on hydrolysis is
