Question

Explain the formation of hydrogen gas by action of dilute HCl on zinc and

testing of H2 gas?
write 8 points about it​

Answer 1

Answer:

We can use a gas syringe to measure the reaction of metals with dilute acid. When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas. We can measure the rate of the reaction by measuring how fast the reaction produces hydrogen. This requires a conical flask and gas syringe.

Answer 2

Answer:

In this Reaction, Zinc Sulphate is formed which is Chalky white in color due to the reaction of the Zinc with dilute sulphuric acid. Hydrogen gas is evolved with the Pop sound. This Reaction is also known as the Displacement Reaction. In this Reaction Hydrogen is Displaced by the Zinc.
