Question

the colour and the nature of the mixture resulting on mixing the two solution into each other.

Answer 1

A double displacement reaction should also occur if an insoluble gas is formed.  Gases such as HCl and NH3  are soluble in water, but some other gases, such as H2S,  are not soluble in water.

Precipitation is the formation of a solid in a solution or inside another solid during a chemical reaction. This process usually takes place when the concentration of dissolved ions in the solution exceeds the solubility product.
