What is backing powder |
|
Answer» Sodium bicarbonate undergoes *decomposition* reaction.By mistake I have typed displacement reaction. Please ignore it? It is *baking powder* not *backing powder.*Answer:-Baking powder is a mixture of baking soda(NaHCO3) along with an edible acid (i.e. either tartaric acid or citric acid).Baking powder is added to food make it soft and spongy (fluffy).When the food material is baked or heated, sodium bicarbonate(NaHCO3) undergoes displacement reaction and forms Sodium carbonate(Na2CO3) along with carbon dioxide gas(CO2) and water vapour(H2O).NaHCO3(s)+ heat----> Na2CO3(s)+H2O(g)+CO2(g)The carbon dioxide gas and water vapour leaves pores in the food material which makes it soft and spongy (fluffy).The tartaric/citric acid present in the baking powder neutralizes the base sodium carbonate and forms a neutral salt which provides flavour to the food material. Is it baking powder or backing powder |
