What is the formula for calculating the boiling point elevation?
ΔT_b = i * K_b * m
ΔT_b = K_b / m
ΔT_b = i * K_f * m
ΔT_b = K_f * m
Questions & Step-by-Step Solutions
What is the formula for calculating the boiling point elevation?
Step 1: Understand that boiling point elevation is how much the boiling point of a liquid increases when a solute is added.
Step 2: Learn the formula: ΔT_b = i * K_b * m.
Step 3: Identify each part of the formula: ΔT_b is the change in boiling point, i is the van 't Hoff factor (number of particles the solute breaks into), K_b is the ebullioscopic constant (a property of the solvent), and m is the molality (concentration of the solute).
Step 4: To use the formula, first determine the values for i, K_b, and m based on your solution.
Step 5: Multiply these values together to find ΔT_b, which tells you how much the boiling point will increase.
