What happens to a substance when it changes from acid to neutral?
a substance which is classified as neutral has a ph of 7- using universal indicator this will result in green. an acid is anything from ph1 to ph6 depending on the concentration of the acid, to neutralise an acid from a ph of 6 or below an alkali is required, so when an acid turns neutral it has either reacted with an alkaline substance or has a higher ph
