During the reaction of some metals with dilute hydrochloric acid, following observations were made.
(a) Silver metal does not show any change
(b) The temperature of the reaction mixture rises when aluminium (Al) is added
`(c)`The reaction of sodium metal is found to be highly explosive
(d) Some bubbles of a gas are seen when lead (Pb)is reacted with the acid Explain these observation giving suitable reasons.

Text Solution

Verified by Experts

Sodium is highly reactive/reaction is highly exothermic, evolving hydrogen gas, which catches fire.
Detailed Answer :
As sodium is highly reactive metal, it reacts with dilute hydrochloric acide vigorously with evolution of heat.
