Question

NaCl, MgCl₂ and CaSO₄ are known as ______.

Options

• 1-1, 2-1, 2-2 types electrolyte respectively

• Strong, weak and strong electrolytes respectively

• Electrolytes with different value of A

• Electrolytes with same molar conductivity

Answer 1

NaCl, MgCl₂ and CaSO₄ are known as 1-1, 2-1, 2-2 types electrolyte respectively.

Explanation:

The types of electrolytes are referred to as 1 - 1, 2 -1, and 2 -2 electrolytes, respectively, depending on the charges on the cation and anion created on the dissociation of the electrolyte in solution.

\[\ce{NaCl -> Na+ + Cl-}\] (1 - 1)

\[\ce{MgCl2 -> Mg2+ + 2Cl-}\] (2 - 1)

\[\ce{CaSO4 -> Ca2+ + SO^{2-}_{4}}\] (2 - 2)
