Front

What does a higher concentration of hydroxide ions indicate about a base?

Back

The higher the concentration of negative (hydroxide) ions in the solution, the stronger the base is.

Front

What happens to the pH when more water is added to a basic solution?

Back

The pH will increase and get closer to 7.
