1. What is Boiling Point Elevation?

Boiling point elevation is a colligative property that occurs when a non-volatile solute is added to a solvent, raising its boiling point. For aqueous solutions, the boiling point increases above 100°C.

2. How Does the Calculator Work?

The calculator uses the boiling point elevation formula:

\[ T_b = 100 + 0.512 \left( \frac{12 / 180}{W} \right) \]

Where:

\( T_b \) — Boiling point of the solution (°C)
12 — Mass of glucose (g)
180 — Molar mass of glucose (g/mol)
0.512 — Ebullioscopic constant for water (°C·kg/mol)
\( W \) — Mass of water (kg)

Explanation: The formula calculates how much the boiling point increases when 12g of glucose is dissolved in a given amount of water.

3. Importance of Boiling Point Calculation

Details: Understanding boiling point elevation is important in various applications including cooking, industrial processes, and pharmaceutical preparations where precise temperature control is necessary.

4. Using the Calculator

Tips: Enter the mass of water in kilograms. The calculator will determine the boiling point of a solution containing exactly 12g of glucose dissolved in that amount of water.

5. Frequently Asked Questions (FAQ)

Q1: Why is glucose used with i=1 in the formula?
A: Glucose is a non-electrolyte that doesn't dissociate in water, so its van't Hoff factor (i) is 1.

Q2: What is the ebullioscopic constant?
A: The ebullioscopic constant (0.512 °C·kg/mol for water) is a property that describes how much the boiling point elevates per molal concentration of solute.

Q3: Does this work for other solutes?
A: The formula can be adapted for other non-electrolytes by changing the mass and molar mass values accordingly.

Q4: What are practical applications of this calculation?
A: This calculation is useful in food science, chemical engineering, and any process where precise boiling temperatures are important for product quality.

Q5: How accurate is this calculation?
A: The calculation provides a theoretical estimate. Actual results may vary slightly due to impurities, atmospheric pressure variations, and other factors.
