\(\mathrm{X}\) is an electrolyte with a concentration of \(0.04 \mathrm{M}\) whose formula is of the type \(\mathrm{X}_2 \mathrm{~A}\). \(\mathrm{Y}\) is a non-electrolyte solution with a concentration of \(0.2 \mathrm{M}\) and has an osmotic pressure equal to \(\mathrm{P}_2\) at room temperature. What is the relationship between the Osmotic pressure \(\pi\) of \(\mathrm{X}\) and \(\mathrm{P}_2\) ?
- A \(\pi=0.04 \mathrm{P}_2\)
- B \(\pi=0.8 P_2\)
- C \(\pi=0.6 P_2\)
- D \(\pi=0.12 \mathrm{P}_2\)
Answer & Solution
Correct Answer
(C) \(\pi=0.6 P_2\)
Step-by-step Solution
Detailed explanation
The osmotic pressure \(\pi\) of a solution is given by the formula \(\pi = iCRT\), where \(i\) is the van't Hoff factor, \(C\) is the molar concentration, \(R\) is the gas constant, and \(T\) is the temperature. For the electrolyte \(X_2A\), it dissociates as…

Assertion: 2-aminoethanoic acid and p-aminobenzene sulphonic acid can exist as Zwitter ions while p-aminobenzoic acid cannot.
Reason: When the acid group is a relatively strong proton donor and the \(-\mathrm{NH}_2\) group is sufficiently basic it can accept a \(\mathrm{H}^{+}\)ion from the acid group to form the dipolar ion.COMEDK 2025 Medium - The ratio of \(\mathrm{N}_2\) and \(\mathrm{O}_2\) gases in the atmosphere is \(4: 1\).
