Question

question 10 of 10
what does it mean if a substance is soluble?

a. it dissolves in water.

b. it is a liquid.

c. it is a solid.

d. it produces a gas.

Explanation:

To determine the meaning of a soluble substance, we analyze each option:

• Option A: Solubility generally refers to the ability of a substance to dissolve in a solvent, and water is a common solvent. A soluble substance dissolves in water (or other solvents).
• Option B: A substance being a liquid has no direct relation to its solubility. Many liquids are not soluble in each other, and solubility is not defined by the state of matter being liquid.
• Option C: Similarly, being a solid does not define solubility. Some solids are soluble, some are not, and solubility is about dissolving, not the state being solid.
• Option D: Producing a gas is a chemical reaction characteristic, not related to solubility which is about dissolving.

So the correct option is A as it aligns with the definition of solubility.

Answer:

A. It dissolves in water.
