QJEEM23Ch4428: JEE Main 2023 Chemistry - Class 12 JEEM23Ch4428 Solution: Coagulating value of the electrolytes and for are 0.09 and…

Coagulating value of the electrolytes AlCl3\mathrm{AlCl}_{3} and NaCl\mathrm{NaCl} for As2S3\mathrm{As}_{2} \mathrm{S}_{3} are 0.09 and 50.04 respectively. The coagulating power of AlCl3\mathrm{AlCl}_{3} is xx times the coagulating power of NaCl\mathrm{NaCl} . The value of x‾\underline{x} is ___________.

Step-by-Step Verified Solution

The coagulating power of an electrolyte is inversely proportional to its coagulating value. That is,

Coagulating power=1Coagulating value\text{Coagulating power} = \frac{1}{\text{Coagulating value}}

Therefore, the coagulating power of AlCl₃ is 10.09\frac{1}{0.09}

and the coagulating power of NaCl is 150.04\frac{1}{50.04}

We are asked to find the factor by which the coagulating power of AlCl₃ is greater than the coagulating power of NaCl. This factor is given by the ratio

x=Coagulating power of AlCl₃Coagulating power of NaCl=10.09150.04=50.040.09x = \frac{\text{Coagulating power of AlCl₃}}{\text{Coagulating power of NaCl}} = \frac{\frac{1}{0.09}}{\frac{1}{50.04}} = \frac{50.04}{0.09}

x=50.040.09≈556.22x = \frac{50.04}{0.09} \approx 556.22

So, the coagulating power of AlCl₃ is approximately 556 times the coagulating power of NaCl.

However, since the problem asks for the nearest integer, the answer would be 556.
