Baking powder contains baking soda and: MCQ with Answer and Explanation

Baking powder contains baking soda and:
A. Magnesium sulfate
B. Calcium carbonate
C. Tartaric acid
D. Sodium chloride
Answer: Option C
Solution (By JKSSB Mock Tests)
Baking powder is a mixture of sodium bicarbonate (baking soda) and a mild edible acid, usually tartaric acid. When moistened and heated, they react to release CO₂, causing dough to rise. Baking soda alone requires an external acidic ingredient. The acid ensures complete reaction and avoids a bitter taste.

Question #1
Plaster of Paris is obtained by heating gypsum at:
A. 473 K
B. 673 K
C. 373 K
D. 573 K

Correct Answer: Option C


Explanation:
Plaster of Paris (CaSO₄·½H₂O) is formed by heating gypsum (CaSO₄·2H₂O) at 373 K (100°C). This causes it to lose 1.5 molecules of water per formula unit. If heated significantly above 473 K, it loses all water and forms dead burnt plaster (anhydrous CaSO₄), which cannot set with water.

Question #2
The property of carbon to form bonds with itself is called:
A. Isomerism
B. Tetravalency
C. Catenation
D. Polymerisation

Correct Answer: Option C


Explanation:
Catenation is the ability of carbon atoms to form long chains, rings, and networks via covalent bonds. This leads to a vast number of organic compounds. Silicon also catenates but to lesser extent.
