Which is a property of acids in aqueous solutions? they feel soapy. they taste bitter. they increase the concentration of h+ ions. they decrease the concentration of h+ ions.

They increase the concentration of H⁺ ions.

Explanation:

By the Arrhenius theory of acid-base, an acid is a substance that, in water, dissociates releasing H⁺ ions and an anion, and a base is a substance that, in water, dissociates releasing OH⁻ ions and a cation.

In aqueous solutions, the acids increase the concentration of H⁺ ions, and they generally have a sour taste. The bases decrease the concentration of H⁺ ions (because it reacts with OH⁻ ions to form water) and feel soapy.

Option (c) is the correct answer.

Explanation:

According to Bronsted-Lowry, acids are the species that dissociate to give hydrogen ion or ions.

For example, this shows that HCl is an acid as it gives hydrogen ions upon dissociation.

When dissolved in water HCl dissociates into ions as follows.

Thus, we can conclude that a property of acids in aqueous solutions is that they increase the concentration of ions.
