Current Question (ID: 18200)

Question:

$\text{Consider the following graph.}$ $\Lambda_m \,(\text{S cm}^2\text{mol}^{-1})$ $c^{1/2}\,\text{(mol/L)}^{1/2}$ $\text{The strong electrolyte in the above graph is represented by:}$

Options:

1. $\text{X}$
2. $\text{Y}$
3. $\text{Both X and Y}$
4. $\text{Data given is not sufficient to predict.}$

Solution:

$\text{HINT: Strong electrolyte dissociates fully.}$ $\text{The Y curve represents weak electrolytes and for weak electrolytes, the curve never touches the y axis. It always remains parallel to the y-axis. As the concentration of weak electrolytes decreases, the value of molar conductivity increases sharply.}$ $\text{The X curve represents strong electrolytes and for strong electrolytes, a straight line is obtained. As the concentration of strong electrolytes decreases, the value of molar conductivity also increases but not sharply.}$
