Answer

Explanation:

Step1: Write the chemical reaction

Nickel (Ni) reacts with hydrochloric acid (HCl) according to the reaction: $Ni(s)+ 2HCl(aq)\rightarrow NiCl_{2}(aq)+H_{2}(g)$.

Step2: Analyze the product

The product of the reaction is nickel - chloride ($NiCl_{2}(aq)$). We are given that nickel - chloride solution is yellow.

Answer:

Yellow, because the reaction between nickel and hydrochloric acid forms nickel - chloride solution which is yellow.
