Question

Ravi conducted an experiment, he added dil.hydrochloric acid to zinc granules in a conical flask. Zinc chloride was formed and hydrogen was liberated. He represented the reaction in the following manner.

$\text{Zn}+\text{HCl}-{\text{H}}_2\to {\text{ZnCl}}_2$

Is the reaction represented properly?

• A. True
• B. False

Answer 1

The correct option is B

False

The representation is wrong. In the chemical reaction the reactants are written on left side of the reaction separated by (+) sign. Similarly, products are written on right side of the reaction separated by (+) sign. The arrowhead points towards products, and shows the direction of the reaction.

So the correct representation for the reaction would be:

$\text{Zn}+\text{HCl}\to {\text{ZnCl}}_2+{\text{H}}_2$
