| Abstract: | Total acid quantity in white vinegar was determined by micro titration and conventional titration. The results showed that two methods had no significant difference, and F examination and t examination were all in the appropriate scope. The accuracy and precision of determining total acid quantity by microscale experiment met with the chemical analysis requirements, experiment reagents were effectively saved, and experiment cost was reduced greatly. |
