• D. decreases the concentration of

Answer 1

The correct option is C

Increases the concentration of ​

An Arrhenius acid is a compound that increases the concentration of ${\text{H}}^{+}$ ions that are present when added to water.
For example: $\text{HCl}$ (Arrhenius acid), when dissolved in water:

$HC{l}_{\left(aq\right)}\to H_{\left(aq\right)}^{+}+C{l}_{\left(aq\right)}^{-}$
