Question

When dissolved in water, Arrhenius base is a compound that:

• A. Increases the concentration of
• B. Increases the concentration of
• C. Decreases the concentration of
• D. does not change the concentration of

Answer 1

The correct option is B

Increases the concentration of

An Arrhenius base is a compound that increases the concentration of $O{H}^{-}$ ions that are present when added to water. For eg: when NaOH is dissolved in water, then it dissociates as shown below:

$NaOH\left(aq\right)\to$ $N{a}^{+}\left(aq\right)$ + $O{H}^{-}\left(aq\right)$
