Definition: This calculator determines the percentage yield of sulphur in an organic compound based on the mass of barium sulfate formed during analysis.
Purpose: It helps chemists and researchers quantify the sulphur content in organic compounds through gravimetric analysis.
The calculator uses the formula:
Where:
Explanation: The formula calculates what percentage of the original compound's mass was sulphur by comparing the barium sulfate produced to the original sample mass.
Details: Accurate sulphur content measurement is crucial for understanding compound composition, purity analysis, and chemical process control.
Tips: Enter the mass of barium sulfate formed (in grams) and the original mass of the organic compound (in grams). Both values must be > 0.
Q1: Why do we use barium sulfate for sulphur analysis?
A: Barium sulfate is highly insoluble, allowing for complete precipitation and accurate gravimetric measurement of sulphur content.
Q2: What does the 32/233 ratio represent?
A: This is the mass ratio of sulphur (32 g/mol) to barium sulfate (233 g/mol), showing what fraction of BaSO4 mass comes from sulphur.
Q3: What are typical percentage yields for sulphur?
A: This varies widely depending on the compound, from near 0% in many hydrocarbons to 50%+ in some sulphur-rich compounds.
Q4: How accurate is this method?
A: Gravimetric analysis is very accurate (±0.2%) when performed carefully with pure samples and complete precipitation.
Q5: Can this be used for inorganic sulphur compounds?
A: Yes, the method works for any compound that can be completely converted to barium sulfate through appropriate reactions.
