An acid reacts to with base to form salt and water. What type of reaction is this?
Right Answer is:
Those reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions.
The reactions between acids and bases to form salts and water are double displacement reactions. For example, sodium hydroxide and hydrochloric acid react to form sodium chloride and water:
NaOH + HCl → NaCl + H2O
In this double displacement reaction, two compounds, sodium hydroxide, and hydrochloric acid react by an exchange of ions to form two new compounds, sodium chloride, and water.
