Question

NaCl, $MgCl_{2}$ and $CaSO_{4}$ are known as

• A. 1 - 1, 2 - 1 and 2 - 2 type electrolytes respectively
• B. strong, weak and strong electrolytes respectively
• C. electrolytes with different value of A
• D. electrolytes with same molar conductivity

Answer 1

Answer: (A)

Depending on the charges on the cation and anion produced on dissociation of the electrolyte in the solution, the type of electrolytes are known as 1 - 1, 2 - 1 and 2 - 2 electrolytes respectively.

$NaCl \rightarrow Na^{+}+Cl^{-}\left(\right.1-1\left.\right)$

$MgCl_{2} \rightarrow Mg^{2 +}+2Cl^{-}\left(\right.2-1\left.\right)$

$CaSO_{4} \rightarrow Ca^{2 +}+SO_{4}^{2 -}\left(\right.2-2\left.\right)$
