In a chemical equation, which symbol should be used to indicate that a substance is in solution?

(s)

(g)

(l)

(aq)

The correct answer is (aq)

The explanation:

when the definition of the solution is a special type of homogeneous mixture composed of two or more substances. when a solute is a substance dissolved in another substance, known as a solvent Ex Na dissolved in water.

and the (aq) is the chemical symbol means aqueous , dissolved in water.

So the correct answer is (aq)

The correct answer is (aq).

Explanation:

In chemical equation, the substance is represented in the four states. These four states are solid, liquid, gas and aqueous.

When the substance is in solution then the state is represented by aqueous.

For example, the sodium chloride is dissolved in the water.  It forms electrolyte. Then the components of the sodium chloride are represented by sodium ion and chloride ion. These ions help in conducting electricity but in pure water, there are no ions.

In the aqueous state, the ions are present but in liquid state, there is no ions.

In a chemical equation, (aq) is used to indicate that a substance is in solution.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
