Which of these solutions has the highest vapor pressure at 25°C? A. 0.10 Molar C6H1206
B. 0.10 Molar NaF
C. 0.10 Molar MgCl2
D. 0.10 Molar K3P04

Solution :

We know, In an electrolyte solution, the number of dissolved particles is larger because the solute breaks apart into ions. The greater the number of ions, the larger the impact on colligative properties will be.

So, the compound which will dissociate into more number of electrolyte has more vapour pressure.

Out of all given compound K₃PO₄ have highest number of particles after dissociation.

Hence, D) is the required solution.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
