Question

The van't Hoff factors for mercurous chloride and mercuric chloride are respectively unity
and greater than unity. Which of the following statements is true about two chlorides?​

Answer 1

Answer:

Shifting cultivation is defined by FAO (1982) as “a farming system in which relatively short periods of cultivation are followed by relatively long periods of fallow.”

Answer 2

Van't Hoff Value is greater than unity

Explanation:

• Van't Hoff Factor value is ratio of observed to calculated colligative property

• Van't Hoff Factor measure effect of solute on colligative property like elevation in BP, depression in FP

• Van't Hoff factor become 1 for non electrolyte solute

• Van't Hoff factor become greater than 1 if solute dissociate into particles

• It become lesser than 1 if the solute particle associate.

• $Hg_{2}Cl_{2} (aq)$ → $Hg^{2+}_{2} (aq) + 2Cl^{-} (aq)$

• Mercurous Chloride gets disscociated into Hg ion and chlorine ion
• So its value of Van't Hoff factor value greater than one
