Summary
In the quantitative estimation of barium as barium sulphate it has been recommended that BaSO4 should be precipitated by adding sulphuric acid of N or 2 N strength, because the results are low in more diluted solutions of sulphuric acid. It has been observed that accurate results within the limits of experimental error can be obtained by precipitating barium sulphate in the presence of alcohol or acetone with dilute sulphuric acid up to 0.167 N strength. When barium sulphate is precipitated with dilute sulphuric acid of strength less than 0.5 N the results are low in the absence of alcohol or acetone.
