What will happen if a solution of sodium hydrogen carbonate is heated? Give the equation of reaction involved.

When we heat sodium hydrogen carbonate ... The main thing to remember is carbondioxide will be evolved...why this is a main thing..? Becoz the co2 evolved helps in baking items like cakes etc to be fluffy... thats why sodium hydrogen carbonate is used in cooking items The reaction for this is 2 NaHCO3 (s)when heated above 80°C gives Na2CO3 (s) + H2O(g) + CO2 (g) I can give u some importance of co2 evolved: The higher the temperature of the mixture, the faster the reaction is. A toffee mixture of golden syrup and sugar will get very heated up,well over 100°C, when heated to boiling point and sodium hydrogen carbonate added to it will decompose very quickly. This causes the toffee to puff up from the gas bubbles formed. If it is cooled quickly by being poured into a cold tin then the toffee will have all these bubbles in it, giving a solid foam. It is known by various names including honeycomb, cinder toffee and hokey-pokey. read less
