How do you get low pH?

Answer 1

The scale of the pH ( power of Hydrogen or negative logerthermic of Hydrogen ion) is from 1 to 14. If is 1 to 7 the liquid said to acidic. If it is 7 to 14 it is said to basic in character.

When we go from pH 1 to 14 acidity reduces.

When we come from pH 14 to 1 acidity increases.

The same is vice-versa for basic character.

Now to for the question how to raise the pH is ?

From pH 1 to 14 it means increasing basic character or reducing acidic character.

This can by achieved by adding strong basic character chemical to the liquid where pH to be raised
