Division 3.3.6 Control of the factor of the ‘carbate solution’

Determine the factor for the carbate solution on the day of use. To do this, titrate 10 ml of the copper sulphate solution (3.2.12) with ‘carbate solution’ after the addition of 100 ml water and 10 ml standard acetate buffer (3.2.10). If the amount used is a ml, the factor f is:

and all the results of the titration are multiplied by this factor.
