The tingling in your mouth is caused by an acid-base reaction. The citric acid is the acid, while the bicarb soda is the base. When an acid and a base is mixed with the saliva in your mouth, a gas is created. It is the carbon dioxide bubbles that give the sherbet its fizz. The icing sugar is a sweetener and the jelly crystals add flavour and colour to the sherbet.
