Estimating the % purity of marble by back titration method
The values for the % purity of marble that I have calculated lie in a close range, however there is a significant difference, of 4.74% in the purity estimated between the 2 individual values. Nonetheless, the deviation is covered by the uncertainty of ±4.84%. However, certain errors have occurred that have caused this deviation in the final results.
