Question

What is the molecular formula of common salt?
1. NaCl
2. HCL
3. H₂O
4. KCL

Answer 1

Correct Answer - Option 1 : NaCl

The correct answer is NaCl.

• Salts
  • Salts are the compounds obtained by the reaction of acids and base, such reactions are called neutralization reactions.
• Common Salt
  • Its chemical name is Sodium Chloride( NaCl).
  • NaOH + HCL = NaCl (Common Salt) + H₂O
  • Its crystals appear brown because of the presence of Impurities.
  • It is an important raw material for various materials of daily use, such as sodium hydroxide, baking soda.
  • It is used in various foodstuffs as a preservative.

• HCL
  • It is a molecular formula of Hydrochloric Acid.
  • It is hydra acids that contain hydrogen but oxygen is absent.
• H2O
  • It is a molecular formula of water.
  • Rainwater is the purest form of water.
  • At 4 degrees celsius, water has maximum density and minimum volume.
• KCL
  • It is the molecular formula of Potassium Chloride.
  • It is a kind of simple salt that is formed by the complete replacement of hydrogen atoms from acid by a metal.
