A) Alkaline solution
B) Acidic solution
C) Bleaching solution
D) Amphoteric solution
Correct Answer: A
Solution :
[a] Alkaline solution Borax \[N{{a}_{2}}\left[ {{B}_{4}}{{O}_{5}}{{(OH)}_{4}} \right]8{{H}_{2}}O\]or Aqueous solution of borax is alkaline due to hydrolysis. Therefore it is used as water softner and cleaning agent. \[N{{a}_{2}}{{B}_{4}}{{O}_{7}}+2{{H}_{2}}O\to \underset{Strong\text{ }alkali}{\mathop{2NaOH}}\,+\underset{weak\text{ }acid}{\mathop{{{H}_{2}}{{B}_{4}}{{O}_{7}}}}\,\]You need to login to perform this action.
