neutral. dip ph paper

Neutralisation reactionA salt is the product of an acid-base reaction and is a much broader term then common table salt as shown in the first reaction.. For example, hydrochloric acid and sodium hydroxide solution react together to form water and sodium chloride solution. ... The H+ ions and OH– ions produce the water, and the Na+ ions and Cl– ions produce the sodium chloride, NaCl(aq).

Answer 2

2) Ammonia is basic in nature because it change red litmus blue.

3) Litmus is obtained from lichen.
It has mave colour in distilled water.
When added to an acidic solution, it turns red and when added Basic solution, it turns blue.

4) Distilled water is neither acidic or Basic.
Litmus paper, red and blue does not change colour indicating that distilled water is neutral in nature.

5) The reaction between and acid and a base is known as Neutralisation.
Salt and water are produced in this process with the evolution of heat.
For example:
HCL + NaOH = NaCL + H2O
