Question

PCL5 + H2O in excess reaction gives

Answer 1

H3PO4+HCL
Actually the equation is
PCl5+4H20--->H3PO4+5HCl
Hope this helped you

Answer 2

When $PCl_5$ is reacted with excess of $H_2O$, it gives phosphoric acid and hydrochloric acid as products.

Explanation:

• In the given reaction, the reactants are phosphorus pentachloride ($PCl_5$) and water ($H_2O$).

• Phosphorus pentachloride ($PCl_5$) is a yellowish white crystalline solid which reacts with water differently based upon the quantity of water.

• When it reacts with less amount of water, it yields phosphorus oxychloride and hydrochloric acid.

• On the other hand, reaction of phosphorus pentachloride ($PCl_5$) with an excess of water yields phosphoric acid and hydrochloric acid as products.
• The chemical equation involved in the reaction is as follows:

$P C l_{5}+4 H_{2} O \stackrel{E x c e s s o f \text { water }}{\longrightarrow} H_{3} P O_{4}+5 H C l$
