Q10 / 180 · KCET 2015 · Chemistry
\( 0.06 \%(\mathrm{w} / \mathrm{v}) \) aqueous solution of urea is isotonic with
- A\( 0.06 \% \) glucose solutio
- B\( 0.6 \% \) glucose solution
- Correct answerC\( 0.01 \mathrm{M} \) glucose solution
- D\( 0.1 \mathrm{M} \) glucose solution
Solution
Molarity of \( 0.06 \%\left(\frac{w}{v}\right) \) aqueous solution of urea
\[ \begin{array}{l} =\frac{0.06 \times 1000}{60 \times 100} \\ =0.01 M \end{array} \]
As osmotic pressure \( (\Pi)= \) CRT
Therefore, \( 0.01 \mathrm{M} \) solution of urea will be isotonic with \( 0.01 \mathrm{M} \) glucose solution
\[ \begin{array}{l} =\frac{0.06 \times 1000}{60 \times 100} \\ =0.01 M \end{array} \]
As osmotic pressure \( (\Pi)= \) CRT
Therefore, \( 0.01 \mathrm{M} \) solution of urea will be isotonic with \( 0.01 \mathrm{M} \) glucose solution
Hence, the correct answer is option: 'C'.
