Question 1
1 / -0

In deodorant soaps, the additive added in deodorant is:

A
glycerol

B
stearic acid

C
potassium bicaronate

D
3, 4, 5-tribromosalicylaldehyde

Solution

Soaps are salts of fatty acids which additives are added for specific reasons. $$3,4,5- tribromo$$ $$salicylaldehyde$$ is used as a deodarant additive.
Question 2
1 / -0

Formula of soap is:

A
$$C_{16}H_{32}COO Na$$

B
$$C_{17}H_{35}COO Na$$

C
$$C_{17}H_{33}COO Na$$

D
$$C_{17}H_{36}COO Na$$

Solution

Solution:- (B) $${C}_{17}{H}_{35}COONa$$
Soaps are sodium or potassium salts of long-chain carboxylic acids.
The formula for soap is $${C}_{17}{H}_{35}COONa$$.
Question 3
1 / -0

The additive used in transparent soaps is:

A
glycol

B
pyrol

C
methanol

D
glycerol

Solution

Glycerol is used as an additive for transparent soaps.
Structure of Glycerol is shown above.
Question 4
1 / -0

Which of the following are used as an antacid to reduce acidity is stomach?

A
Sodium carbonate and magnesium hygroxide

B
Magnesium hydroxide and sodium hydroxide

C
Sodium bicarbonate and calcium hydroxide

D
Sodium bicarbonate and magnesium hydroxide

Solution

Acidity of stomach has to be neutralized by a base, without affecting the cells of the body. So, sodium bicarbonate and magnesium hydroxide are helpful for that.

$$NaHCO_3+HCl\rightarrow NaCl+H_2O+CO_2\uparrow$$
(Neutralized)
$$Mg(OH)_2+2HCl\rightarrow MgCl_2+2H_2O$$
Question 5
1 / -0

Salts of alkylbenzene sulphonates are called:

A
soaps

B
detergents

C
both $$(A)$$ and $$(B)$$

D
None of the above

Solution

Detergents is a mixture of surfacts with cleaning properties in dilute solution. These substances are usually Alkylbenzene -sulfonates, which are more soluble in hard water than soap, because the polar sulfonate is less likely than polar. Carboxylate (soap) to bind calcium and other ions in hard water.
Question 6
1 / -0

Soaps are salts of :

A
Fatty Acids

B
Proteins

C
Oils

D
None of these

Solution

Soap is term used for salt of fatty acids. Soaps acts as surfactants, emulsifying oils to enable them to be carried away by water. In industry soaps are used a thickness, Lubricants, catalysts, etc.
Question 7
1 / -0

Sodium chloride is used in soap industry for soap's __________ .

A
decomposition

B
removal of hardness

C
precipitation

D
None of the above

Solution

The addition of salt (sodium chloride) to the crude form of soap forms fatty-acid salts. The sodium ions from the sodium chloride bond with the fatty acid, forming a product that is less soluble in water. Because of this reduced solubility, the soap leaves the solution and forms a solid mass. This process of "dropping" out of the solution is called precipitation.
Therefore option C is correct.
Question 8
1 / -0

Which one of the following is employed as a tranquilizer drug?

A
Promethazine

B
Valium

C
Naproxen

D
Mifepristone

Solution

Valium is a tranquilizer drug. It is mainly used to treat anxiety, insomnia, and symptoms of acute alcohol withdrawal. It acts by enhancing the effects of gamma-aminobutyric acid (GABA) in the brain.
Question 9
1 / -0

Which of the following is used as a tranquilizer?

A
Seconal

B
Luminal

C
Barbituric acid derivatives

D
All of these

Solution

Seconal, luminal, barbituric acid derivatives are tranquilizers. They are used to treat mental illness, anxieties, tension and sleeplessness. They are often called depressants because they suppress the central nervous system and slow the body down.
Question 10
1 / -0

The class of drugs used for the treatment of stress is:

A
analgesics

B
antiseptic

C
antihistamine

D
tranquilizers

Solution
