Weekly Quiz Competition

Question 1
1 / -0

Which of the following is known as invert soap?

A
Pentaerythritol monostearate

B
Trimethyl stearyl ammonium bromide

C
Ethoxylated nonphenol

D
Sodium stearyl sulphate

Solution

Invert soap is a class of synthetic detergents in which the surface active part of the molecule is the cation.
It is an cationic detergent.
Trimethyl stearyl ammonium bromide is cationic detergent and also called invert soap.
Question 2
1 / -0

Histamine is an organic nitrogenous compound involved in local immune response as well as regulating physiological function in the gut and acting as neuro transmitter. The drug used as:

A
vasodilator

B
analgesics

C
antacid

D
antiseptic

Solution
Question 3
1 / -0

Which of the following substance is an antacid?

A
$$NaCl$$

B
$$Mg(OH)_2$$

C
$$HCl$$

D
$$H_2SO_4$$

Solution

Due to its mildly basic and non-toxic nature, magnesium hydroxide is widely used as an antacid to neutralize stomach acids and prevent indigestion and heartburn.

It is also used as a laxative, antiperspirant, underarm deodorant, to treat sores, in wastewater treatment, and as a fire retardant.

Therefore, the correct option is B.
Question 4
1 / -0

Which of the following is an anionic detergent?

A
Glyceryl oleate

B
Sodium stearate

C
Sodium lauryl sulphate

D
Cetyltrimethyl ammonium bromide

Solution

Anionic detergents are sodium salts of sulphonated long chain alcohols or hydrocarbons. In anionic detergents, the anionic part of the molecule is involved in the cleansing action. $${Sodium}^{+}{(lauryl sulphate)}^{-}$$ is an anionic detergent.
Cetyltrimethylammonium bromide is a popular cationic detergent and is used in hair conditioners. Non-ionic detergents do not contain any ion in their constitution. Glyceryl Oleate is the ester of glycerin and oleic acid. Sodium stearate is the sodium salt of stearic acid.
Option c is correct
Question 5
1 / -0

Which of the following is not used as an antacid ?

A
Magnesium hydroxide

B
Sodium carbonate

C
Sodium bicarbonate

D
Aluminium phosphate

Solution

An antacid is a substance which neutralizes stomach acidity and is used to relieve heartburn, indigestion or an upset stomach.
Example- $$Mg(OH)_2, Na_2CO_3, NaHCO_3$$.
Aluminum phosphate is not used as an antacid.
Hence, the correct option is D.
Question 6
1 / -0

Which of the following is used for preservation of biological substances and food materials?

A
Liquid ammonia

B
Liquid dinitrogen

C
Liquid sulphur dioxide

D
Carbon dioxide

Solution

Liquid nitrogen has many uses, mainly based on its cold temperature and low reactivity. Examples of common applications include:
1. The freezing and preservation of food products
2. The preservation of biological samples, such as sperm, eggs, and animal genetic sample.
3. Use as a coolant for superconductors, vacuum pumps, and other materials and equipment.
4. Use in cryotherapy to remove skin abnormalities.
5. The shielding of materials from the oxygen exposure
6. The quick freezing of water or pipe to allow work on them when valves aren't available
8. A source of extremely dry nitrogen gas.
Question 7
1 / -0

Terfenadine is commonly used as a/an ?

A
Tranquillizer

B
Antithistamine

C
Antimictobial

D
Antifortility drug

Solution

Terfenadine is an antihistamine formerly used for the treatment of allergic conditions. It was brought to market by Hoechst MArion Roussel(now Sanofi Aventis) and was marketed under various brand names including Seldane in United states, Triludan in United kingdom. It was superseded by fexofenadine in 1990s due to the risk of a particular type of disruption of the electrical rhythms of the heart and has been withdrawn from market.
Question 8
1 / -0

Which of the following is used as a preservative to protect processed food?

A
Sodium sulphate

B
Saccharin

C
Sucralose

D
Sodium metabisulphite

Solution

Sodium sulphate is used as wine making industry to prevent oxidation and it is used as antimicrobial agent as food preservative protects food coloring and browning.
Question 9
1 / -0

Milk can be preserved by adding a few drops of:

A
formic acid solution

B
formaldehyde solution

C
acetic acid solution

D
acetaldehyde solution

Solution

Formic acid $$\Rightarrow H - \overset{O}{\overset{||}{C}} - OH$$
Formic acid is used to preserve Milk.
Question 10
1 / -0

Identify the correct statement.

A
Soaps are better than detergents in hard water

B
Soaps are salts of alkyl benzene sulphonic acids

C
Detergents clean well even in acidic medium

D
The non ionic hydrocarbon end of soap has property to attract water

Solution

Detergents are sodium salts of long chain Alkyl sulphates or a long chain of Alkyl benzene sulphonates.
$$\bullet$$ They are non-biodegradable.
$$\bullet$$ They can be used in hard water and acidic medium.
