The phrase that describes a characteristic of an Arrhenius base is that Arrhenius base add hydroxide ions to the solution ( answer C)
Explanation
Arrhenius base is a substance that increases the concentration of OH- in aqueous solution.
The Common Arrhenius base are group 1 and 2 hydroxide such as LiOH, NaOH , Ba(OH)2 among others.
for example NaOH dissociate as follows , NaOH → Na+(aq) + OH- (aq)
Answer: Option (C) is the correct answer.
Explanation:
According to Arrhenius, bases are the species which when dissolved in water will give hydroxide ions, that is, [tex]OH^{-}[/tex].
For example, [tex]NaOH \rightarrow Na^{+} + OH^{-}[/tex]
So, NaOH is a base.
On the other hand, species which tend to dissociate in water to given hydrogen ions, that is, [tex]H^{+}[/tex] ions are known as acids.
For example, [tex]HCl \rightarrow H^{+} + Cl^{-}[/tex]
So, HCl is an acid.
Thus, we can conclude that the phrase adds hydroxide ions to the solution best describes a characteristic of an Arrhenius base.
