Baking powder contains baking soda and : 

chemistry substances in common use preparation, properties and uses of baking soda chemical from common salt compounds of carbon

  1. potassium hydrogen tartarate

  2. calcium bicarbonate

  3. sodium carbonate

  4. vinegar

Show answer
Correct Option: A
Explanation:

Baking powder is dry chemical leavening agent a mixture of carbonate or bicarbonate and a weak acid. A typical acid in such formulations is cream of tartar derivative of tartaric acid. Commercially it is sodium bicarbonate.

Sodium sesquicarbonate is 

chemistry substances in common use preparation, properties and uses of baking soda chemical from common salt compounds of carbon

  1. $\displaystyle Na _{2}CO _{3}NaHCO _{3}$

  2. a double salt

  3. trisodium hydrogen discrabonate

  4. water softner

Show answer
Correct Option: A,B,C,D
Explanation:
Sodium sesquicarbonate (Systematic name trisodium hydrogendicarbonate) $Na _3H(CO _3) _2$ is a double salt of sodium bicarbonate and sodium carbonate($\displaystyle Na _{2}CO _{3}NaHCO _{3}$), and has a needle-like crystal structure. However, the term is also applied to an equimolar mixture of those two salts, with whatever water of hydration the sodium carbonate includes, supplied as a powder.
odium sesquicarbonate is used in bath salts, swimming pools, as an alkalinity source for water treatment.
Hence options A,B,C & D are correct.

The element which is not common between the compounds called baking soda and soda ash is:

chemistry substances in common use preparation, properties and uses of baking soda chemical from common salt compounds of carbon

  1. nitrogen

  2. hydrogen

  3. oxygen

  4. sulphur

Show answer
Correct Option: B
Explanation:

Baking soda formula is $NaHCO _3$.

Soda ash formula is $Na _2CO _3$.
So, hydrogen atom $(H)$ is not common between the compounds of baking soda and soda ash.
So, the answer is $B$.

Baking soda is a/an:

chemistry substances in common use preparation, properties and uses of baking soda chemical from common salt compounds of carbon

  1. acidic substance

  2. basic substance

  3. neutral substance

  4. none of these

Show answer
Correct Option: B
Explanation:

Baking soda is sodium bicarbonate or sodium hydrogen carbonate. It has slightly salty, alkaline taste resembling that of washing soda. Its alkalinity in aqueous solution is because of formation of carbonic acid and hydroxide ion.
${ HCO } _{ 3 }^{ - }+{ H } _{ 2 }O\rightarrow { H } _{ 2 }{ CO } _{ 3 }+{ OH }^{ - }$

One of the constituents of baking powder is sodium hydrogen carbonate, the other constituent is:

chemistry substances in common use preparation, properties and uses of baking soda chemical from common salt compounds of carbon

  1. acetic acid

  2. oxalic acid

  3. carbonic acid

  4. tartaric acid

Show answer
Correct Option: D
Explanation:

Tartaric acid used in baking powder where it serves as the source of acid that reacts with baking soda. This reaction produces carbon dioxide gas and lets products rise using active yeast cultures as a source of carbon dioxide gas.

Baking powder contains Sodium Hydrogen Carbonate, and__________.

chemistry substances in common use preparation, properties and uses of baking soda chemical from common salt compounds of carbon

  1. tartaric acid

  2. sodium carbonate

  3. calcium chloride

  4. acetic acid

Show answer
Correct Option: A
Explanation:
Baking powder contains Sodium Hydrogen Carbonate $NaHCO _3$, and tartaric acid. It is used for increasing the volume and lightening the texture of baked goods. It releases carbon dioxide gas into a batter or dough through an acid-base reaction, causes bubbles in the wet mixture which expands and thereby  leavening the mixture.

Which of the following compounds is known as baking soda?

chemistry substances in common use preparation, properties and uses of baking soda chemical from common salt compounds of carbon

  1. Sodium carbonate

  2. Calcium carbonate

  3. Sodium bicarbonate

  4. Calcium bicarbonate

Show answer
Correct Option: C
Explanation:

Sodium Bicarbonate (NaHCO3) is called baking soda because when heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread.

Sodium bicarbonate is also known as:

chemistry substances in common use preparation, properties and uses of baking soda chemical from common salt compounds of carbon

  1. washing soda

  2. baking soda

  3. glauber's salt

  4. lime soda

Show answer
Correct Option: B
Explanation:

Sodium bicarbonate, also commonly known as baking soda, is commonly seen as a white, fine powder and has the chemical formula NaHCO3. It has one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms. It is a very useful chemical that is alkaline in nature.
