Vedclass · Answer

(B) When $Borax$ $(Na_2B_4O_7 \cdot 10H_2O)$ is dissolved in water,it undergoes hydrolysis to form orthoboric acid $(H_3BO_3)$ and sodium hydroxide $(NaOH)$.$Na_2B_4O_7 + 7H_2O \rightarrow 2NaOH + 4H_3BO_3$.Since $NaOH$ is a strong base and $H_3BO_3$ is a weak acid,the resulting aqueous solution is alkaline (basic) in nature.This basic nature is responsible for the cleansing action of $Borax$.

Which of the following is responsible for the cleansing action of $Borax$?
