Chapter 13, Problem 140E

Interpretation Introduction

Interpretation:

When salt is dissolved into water, it dissociates into ions forming cations and anions.

When salt is dissolved into water, it gets dissolved and dissociates into ion.

MF_x→M^x++xF ^-

In case of strong salt, it is completely dissociated into elemental ion.

Concept introduction:

∆T_b = i×m×K_b

Here,

∆T_b = Temperature different of solution,m= molality, K_b = boiling constsnt

$\text{Molality = }\frac{\text{No}\text{. of moles of solute}}{Kg\text{ of solvent}}$

To determine: The formula of the salt MF_X
