Question

Which phrase describes a characteristic of an Arrhenius base?

A. adds hydronium ions to the solution
B. accepts hydronium ions
C. adds hydroxide ions to the solution
D. accepts hydroxide ions

Answer 1

Answer: Option (C) is the correct answer.

Step-by-step explanation:

According to Arrhenius, bases are the species which when dissolved in water will give hydroxide ions, that is,
`OH^(-)`.

For example,
`NaOH \rightarrow Na^(+) + OH^(-)`

So, NaOH is a base.

On the other hand, species which tend to dissociate in water to given hydrogen ions, that is,
`H^(+)` ions are known as acids.

For example,
`HCl \rightarrow H^(+) + Cl^(-)`

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.

Answer 2

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)
