The image above represents boiling point elevation.

To compute for the boiling point elevation, three parameters are needed and these parameters are **Van’t Hoff’s Factor (i), ebullioscopic constant (K _{b}**) and

**Molality**.

The formula for calculating boiling point elevation:

δT_{b} = iK_{b} x Molality

Where;

δT_{b} = boiling point elevation

i = Van’t Hoff’s Factor

K_{b} = ebullioscopic constant

Molality

Let’s solve an example;

Find the boiling point elevation when the Van’t Hoff’s Factor is 42, ebullioscopic constant is 60 and molality of 180.

This implies that;

i = Van’t Hoff’s Factor = 42

K_{b} = ebullioscopic constant = 60

Molality = 180

δT_{b} = iK_{b} x Molality

δT_{b} = (42)(60) x 180

δT_{b} = (2520) x 180

δT_{b} = 453600

Therefore, the **boiling point elevation** is **453600 °C m-1.**

**Calculating the Molality using the Boiling Point Elevation, Van’t Hoff’s Factor and Ebullioscopic Constant.**

Molality = ^{δTb} / _{iKb}

Where;

Molality

δT_{b} = boiling point elevation

i = Van’t Hoff’s Factor

K_{b} = ebullioscopic constant

Let’s solve an example;

Find the molality with a boiling point elevation of 120 and a van’t hoff’s factor of 32 with a ebullioscopic constant of 12.

This implies that;

δT_{b} = boiling point elevation = 120

i = Van’t Hoff’s Factor = 32

K_{b} = ebullioscopic constant = 12

Molality = ^{δTb} / _{iKb}

Molality = ^{120} / _{384}

Molality = 0.3125

Therefore, the **molality **is **0.3125.**

**Calculating the Van’t Hoff’s Factor when the Boiling Point elevation, Ebullioscopic Constant and Molality is Given.**

i = ^{δTb} / _{Kb x molality}

Where;

i = Van’t Hoff’s Factor

δT_{b} = boiling point elevation

K_{b} = ebullioscopic constant

Molality

Let’s solve an example;

Find the van’t hoff’s factor when the boiling point elevation is 240 with a molality of 10 and an ebullioscopic constant of 15.

This implies that;

δT_{b} = boiling point elevation = 240

K_{b} = ebullioscopic constant = 15

Molality = 10

i = ^{δTb} / _{Kb x molality}

i = ^{240} / _{15 x 10}

i = ^{240} / _{150}

i = 1.6

Therefore, the **Van’t Hoff’s Factor **is **1.6.**

**Calculating the Ebullioscopic Constant when Boiling Point Elevation, Molality and Van’t Hoff’s Factor is Given.**

k_{b} = ^{δTb} / _{i x molality}

Where;

K_{b} = ebullioscopic constant

i = Van’t Hoff’s Factor

δT_{b} = boiling point elevation

Molality

Let’s solve an example;

Find the ebullioscopic constant when the boiling point elevation is 180 with a molality of 8 and a van’t hoff’s factor of 15.

This implies that;

δT_{b} = boiling point elevation = 180

i = Van’t Hoff’s Factor = 15

Molality = 8

k_{b} = ^{δTb} / _{i x molality}

k_{b} = ^{180} / _{15 x 8}

k_{b} = ^{180} / _{120}

k_{b} = 1.5

Therefore, the **ebullioscopic constant **is **1.5.**
