Combustion Analysis Empirical Formula Calculator — Frequently Asked Questions
Q1 Why is oxygen determined by subtraction in combustion analysis? ▾
Because combustion occurs in a stream of excess atmospheric oxygen gas (O2), oxygen in the products comes from both the compound and the atmosphere. Oxygen in the original sample must therefore be calculated by subtracting C and H from total starting mass.
