Division 6 Calculation of results

United Kingdom

The content of carbonates, expressed as calcium carbonate, is calculated by using the formula:

X = \frac{V \times 100}{V_{1} \times 2m}

where:

% (w/w) of carbonates in the sample, expressed as calcium carbonate

ml of CO₂ released by the portion of the sample.

V₁

ml of CO₂ released by 0,5 g of CaCO₃.

weight, in grammes, of the portion of the sample.
