All of the following happen when an acid reacts completely with a base EXCEPT: the pH moves to 0 on the pH scale the pH is equal to 7 the solution mixture is neutralized salt and water form

the pH moves to 0 on the pH scale

Explanation:

A base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydrogen ions in water.

Neutralisation reaction  is defined as the chemical reaction in which an acid reacts with a base to produce a salt and water molecule. The ions from acid are neutralised by ions from base.

Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH of 7.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
