Question

$P_4{O}_6$ reacts with water to give :

• A. $H_{3}P{O}_3$
• B. $H_4{P}_2{O}_7$
• C. $HP{O}_3$
• D. $H_{3}P{O}_4$

Answer 1

The correct option is A $H_{3}P{O}_3$

When $P_4{O}_6$ reacts with water it gives phosphoric acid.

$P_4{O}_6\left(s\right)+6H_{2}O\left(l\right)\to 4H_{3}P{O}_3\left(aq\right)$

Hence option A is correct.
