Question

A substance that gives up a proton during a chemical reaction, raising the hydrogen ion concentration of water, is most appropriately called _____. See section 2.2 (page 62) .

Answer 1

The answer is an acid.

That is a substance that gives up a proton during a chemical reaction, raising the hydrogen ion concentration of water, is most appropriately called an acid.

Acid is a substance that gives protons in its aqueous solution, and that the hydrogen ion concentration of that aqueous solution .

Answer 2

Explanation:

A substance that is able to increase hydrogen ion concentration in water or a solvent is known as an acid.

For example, when HCl is dissolved in water then it will lead to release of hydrogen ions ($[H^{+}]$) or hydronium ions ($[H_{3}O^{+}]$) into water.

The reaction will be as follows.

            $HCl + H_{2}O \rightarrow H_{3}O^{+} + Cl^{-}$

Thus, we can conclude that a substance that gives up a proton during a chemical reaction, raising the hydrogen ion concentration of water, is most appropriately called an acid.
