Procedure

The above-mentioned 1/10 N-KOH solution in THF is prepared as follows. First 1.5 g of KOH is dissolved in about 3 ml of water, and 200 ml of THF and 30 ml of water are added thereto, followed by stirring. After standing, a uniform clear solution is formed, if necessary, by adding a small amount of methanol if the solution is separated or by adding a small amount of water if the solution is turbid. Then, the factor of the 1/10 N-KOH-THF solution thus obtained is standardized by a 1/10 N-HCl standard solution.
