Answer 1

Answer:

When NaOH is added to HCl neutralisation reaction takes place and a salt NaCl with some water is produced. The reason for this reaction is that when a base acts on an acid or an acid acts on a base they nullify each other and get neutralised. pH of a solution will be 7 when its neutral ,i.e. neither acidic nor basic.

Answer 2

Answer:

Hydrochloric acid reacts with sodium hydroxide to form sodium chloride (the salt) and water. Sodium chloride is made up of Na+ cations from the base (NaOH) and Cl- anions from the acid (HCl). HCl+NaOH→H2O+NaCl. Hydrogen bromide reacts with potassium hydroxide to form potassium bromide (the salt) and water.Nov 25, 2010
