Answer

Answer:

C. It reacts with active metals to form a gas.

Explanation:

Step1: Recall acid - base properties

Acids taste sour, not bitter. So option A is incorrect.

Step2: Recall acid - metal reactions

Acids react with active metals (such as zinc, magnesium etc.) according to the general equation $M + nH^+ \rightarrow M^{n+}+\frac{n}{2}H_2(g)$ where $M$ is the metal. They do react with active metals to form hydrogen gas. So option B is incorrect and option C is correct.

Step3: Recall acid - litmus paper reaction

Acids turn blue litmus paper red. So option D is incorrect.
