Summary
A method has been presented for the determination of bicarbonates in soap products based on the quantitative loss of CO2 which occurs when bicarbonates are heated to 260°C. for 30 minutes. The method is subject to errors arising from the solubility of sodium bicarbonate in alcohol and the use of a large mathematical factor in calculating the bicarbonate content. In the absence of a more exact method the procedure gives results which are of great interest and value in soap analysis.
