Question

Consider the reaction below.

Zn(s) + 2HCl(aq) → H₂(g) + ZnCl₂(aq)
Which product is a substance that is dissolved in solution?
a) Zn
b) H2
c) HCl
d) ZnCl₂

Answer 1

The product dissolved in solution in the reaction Zn(s) + 2HCl(aq) → H₂(g) + ZnCl₂(aq) is d. ZnCl₂ (zinc chloride).

Step-by-step explanation:

In the reaction Zn(s) + 2HCl(aq) → ZnCl₂(aq) + H₂(g), the product that is dissolved in solution is ZnCl₂ (zinc chloride). This occurs because the reaction is a single replacement reaction where metallic zinc reacts with aqueous hydrochloric acid to form an aqueous solution of zinc chloride and hydrogen gas. The zinc metal replaces hydrogen in combination with chloride, resulting in zinc ions and chloride ions in solution, which constitutes the aqueous zinc chloride.
