Question

How baking powder is formed?

Answer 1

Hint:As we know that baking powder is dry in nature, and solid powder. It is a mixture of weak acid and weak base. It is found that the reaction between both acid and base can be prevented by adding a buffer. We can see that baking powder is used in cooking.

Complete step-by-step answer:- Baking powder is a mixture that contains two chemicals. It is found that the two chemicals are sodium hydrogen carbonate and sodium bicarbonate. And the weak acid is tartaric acid.
- It is found that sodium bicarbonate is also called sodium hydrogen carbonate.
- We can see the reaction of sodium hydrogen carbonate with acid at high temperature as:
$NaHC{{O}_{3}}+{{H}^{+}}\to N{{a}^{+}}+C{{O}_{2}}+{{H}_{2}}O$
- As we know that when sodium hydrogen carbonate reacts with acid and there is formation of products that are carbon dioxide and water takes place. sodium hydrogen carbonate and tartaric acid
- It is found that in the above reaction carbon dioxide is liberated that makes bread and cake puffy.
 - Hence, we can conclude that Baking powder is a mixture of sodium hydrogen carbonate and tartaric acid

Note:- As we know that the molecular formula of sodium hydrogen carbonate is $NaHC{{O}_{3}}$ .
- It is found that tartaric acid is soluble in water and contains two alcohol functional groups and two carboxylic acids in its structure.
