Base Chemistry Example 5

Follow the full solution, then compare it with the other examples linked below.

A base is added to water. What happens to the hydrogen-ion concentration, and why?

1
A base removes $\text{H}^+$ ions or increases $\text{OH}^-$ ions in solution.
2
That lowers the hydrogen-ion concentration, so the solution becomes more basic.

Answer

The hydrogen-ion concentration decreases because a base accepts

\text{H}^+

or adds

\text{OH}^-

Bases oppose acids by reducing the effective concentration of hydrogen ions in solution. This pushes the solution toward higher pH values.

About Base

A substance that accepts $\text{H}^+$ ions (protons) or donates $\text{OH}^-$ ions when dissolved in solution, raising the pH above 7.

According to the Arrhenius definition, what makes a substance a base? Give two examples.

Ammonia ([formula]) is a base but does not contain [formula]. Using the Brønsted-Lowry definition, e

Identify whether NaOH is an acid or a base. Write the dissociation equation in water.

Is a solution with pH = 12 acidic, neutral, or basic?
