Percentage Yield Formula:
From: | To: |
Definition: Percentage Yield of Halogen is a measure of the quantity of moles of halogen formed in relation to the reactant consumed in an organic compound.
Purpose: It helps chemists determine the halogen content in organic compounds through silver halide (AgX) formation.
The calculator uses the formula:
Where:
Explanation: The formula calculates the percentage of halogen in the organic compound based on the mass of silver halide formed.
Details: Accurate halogen yield determination is crucial for understanding organic compound composition, purity analysis, and reaction mechanisms.
Tips: Enter the atomic mass of the halogen (e.g., 35.5 for Cl, 79.9 for Br), mass of AgX formed, and mass of the organic compound. All values must be > 0.
Q1: Why is silver (Ag) part of the calculation?
A: The method involves converting halogen in the organic compound to silver halide (AgX) for measurement.
Q2: What are typical atomic masses for halogens?
A: Fluorine (19.0), Chlorine (35.5), Bromine (79.9), Iodine (126.9).
Q3: What if my compound contains multiple halogens?
A: This calculator assumes a single halogen type. For mixed halogens, use weighted average atomic mass.
Q4: How accurate is this method?
A: It provides good estimates but may have 1-3% error due to practical limitations in lab measurements.
Q5: Can I use this for fluorine compounds?
A: No, as silver fluoride (AgF) is soluble and doesn't precipitate like other silver halides.
