Hgl2 is insoluble in water. This solute is added into Kl solution.Q.Pa...
The ratio of the concentration of particles formed when a substance is dissolved to the concentration of the substance by mass.
The extent to which a substance associates or dissociates in a solution is described by the Van’t Hoff factor. For example, when a non-electrolytic substance is dissolved in water, the value of i is generally 1.

Explanation:
When Hgl2 is added into KI solution, it undergoes a reaction with KI to form the insoluble compound Kgl and the soluble compound HI. The balanced chemical equation for this reaction is:
Hgl2 + 2KI -> 2Kgl + 2HI
Definition of vant Hoff factor:
The vant Hoff factor (i) is defined as the ratio of moles of particles in a solution to the moles of solute dissolved. It takes into account the dissociation or association of solute particles in the solution.
Initial vant Hoff factor of KI:
The initial vant Hoff factor of KI is 2, because KI dissociates into two ions in the solution: K+ and I-.
Change in vant Hoff factor:
When Hgl2 is added to the KI solution, it reacts to form Kgl and HI. Kgl is insoluble and does not dissociate further, so it does not contribute to the vant Hoff factor. On the other hand, HI is a strong acid and completely dissociates into H+ and I- ions in the solution.
Therefore, the total moles of solute particles in the solution increase due to the dissociation of HI. This increase in the moles of solute particles leads to a decrease in the vant Hoff factor.
Explanation of the correct answer:
In this case, the correct answer is option 'C', which states that the vant Hoff factor decreases by 1 unit.
This is because the initial vant Hoff factor of KI is 2, but after the addition of Hgl2 and the formation of HI, the vant Hoff factor decreases to 1. This is because the addition of Hgl2 does not contribute any additional moles of particles to the solution, while the dissociation of HI increases the moles of solute particles.
Therefore, the overall change in the vant Hoff factor is a decrease of 1 unit.
