any base
Concentrated nitric acid can be neutralized by slowly adding a base, such as sodium hydroxide, calcium carbonate, or ammonia solution, while stirring continuously until the pH reaches around 7. It is important to handle the neutralization process carefully due to the exothermic nature of the reaction and the potential for splattering.
It will neutralise the alkali and then turn the liquid to an acid.
Yes. Ammonia is a base that will neutralize sulfuric acid.
by adding acid (vinegar works)
pH = 7.00 at 25oC
Add a base, such as NaOH, NH3, or LiOH
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.
