A) \[NaHC{{O}_{3}}\]
B) \[N{{a}_{2}}C{{O}_{3}}\]
C) \[NaHC{{O}_{3}}.6{{H}_{2}}O\]
D) \[N{{a}_{2}}C{{O}_{3}}.10{{H}_{2}}O\]
Correct Answer: A
Solution :
Baking powder is chemically sodium bicarbonate\[(NaHC{{O}_{3}}).\]It also contains small amount of tartaric acid which neutralizes the bitter effect of \[N{{a}_{2}}C{{O}_{3}}\]which is formed due to decomposition of \[NaHC{{O}_{3}}\] Hence, the correct option is (a).
