Question

Borax is used as a cleansing agent because when it is dissolved in water it gives a/an:

• A. Alkaline solution
• B. Acidic solution
• C. Bleaching solution
• D. Colloidal solution

Answer 1

The correct option is A Alkaline solution

Borax is $N{a}_2{B}_4{O}_7.10H_{2}O$
Borax when dissolved in water gives an alkaline solution as it a salt of weak acid and strong base.
$N{a}_2{B}_4{O}_7+7H_{2}O\to 2Na\left[B\right(OH{)}_4]+2H_{3}B{O}_3$
