Add a base, such as NaOH, NH3, or LiOH
by mixing it with base

by the addition of base
any base
It will neutralise the alkali and then turn the liquid to an acid.
Yes. Ammonia is a base that will neutralize sulfuric acid.
pH = 7.00 at 25oC
by adding acid (vinegar works)
Adding an acid the pH decrease.
Powdered lime, to neutralise the acid.
They neutralise each other, assuming you neutralise a volume of acid with a base of the same molarity they completely cancel each other out leaving water and a salt. The salt differs depending on the acid and base used.
alkali bases pH greater than 7
