Question

prepare aqueous solution of various solid salts available in laboratory observe what happen when aqueous solution of sodium hydroxide is added to these. prepare the chart of double displacement reaction based on displacement reaction based on these observation

Answer 1

Double displacement reactions are the reactions where one component of each of the molecule reacting exchanges to form a new product.

To form two new products, the cations and anions switch places and react. AB + CD -> AD+ CB.

In neutralization, HCl(aq) +NaOH(aq) -> NaCl(aq)+H20(l).In this an acid is reacting wth a base and forming salt and water.
