Question

The variation in ${\Lambda }_m$ with concentration for a strong electrolyte can be represented by the equation,
${\Lambda }_m={\Lambda }_m^{\circ }-A{C}^{1/2}$
The value of constant $A$ for a given solvent and temperature depends upon the type of electrolyte i.e., cations and anions produced on dissociation of electrolyte in the solution.
$NaCl$, $MgC{l}_2$ and $CaS{O}_4$ 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)

Correct answer is (a) $1-1$, $2-1$, and $2-2$ type electrolytes respectively
