Question
Scouts spend the night camping beside the water. They are required to wash everything in seawater.
What kind of material would be best for successfully washing their clothes?
- Soaps
- Bleach
- Detergent
- Antiseptic
Hint:
The substance containing potassium salts works well.
The correct answer is: Soaps
Soaps would be best for successfully washing their clothes.
Brine soap is a potassium salt, not a sodium salt. Sodium and potassium are both alkali metals. Relatively high concentrations of salt (sodium chloride) in seawater reduce the solubility of soaps made with sodium hydroxide due to the salting-out effect. Potassium soap is more soluble in seawater than sodium soap, so it is more effective in seawater.

Which of the following are the allotropes of carbon?
The correct option is c) Both A and B.
When an element exists in multiple crystal forms, those forms are called allotropes. The two most common allotropes of carbon are diamond and graphite. The crystal structure of diamond is an infinite three-dimensional arrangement of carbon atoms, forming a structure in which each bond forms an equal angle with an adjacent bond. When the ends of the bond are joined, the structure becomes a tetrahedral, four-sided, three-sided pyramid structure.

Which is the 5th rare gas present in the atmosphere?
The correct option is d)Xe.
- Xenon gas is the rarest gas on earth. Air contains only 0.000009% xenon. Therefore, it is only used when no other alternative lighter gas is available.
- In addition to xenon, neon and krypton are present at 0.0018% and 0.00011%, respectively.
- Applications of xenon gas include the manufacture of automotive headlights, semiconductors, plasma display panels and flash cameras.
- In addition, xenon also has medical applications, including its anesthetic properties.
