Vedclass · Answer

(B) solution of $NaHCO_3$ in water is alkaline in nature due to the hydrolysis of the $HCO_3^-$ ion. The hydrolysis reaction is: $HCO_3^- + H_2O \rightleftharpoons H_2CO_3 + OH^-$. Due to the presence of $OH^-$ ions,the solution is basic. Methyl orange is a pH indicator that turns yellow in basic solutions (pH range $4.4 - 6.2$ is the transition range,but it appears yellow in alkaline media).

$A$ solution of sodium bicarbonate in water turns:
