- the fresh bath prepared with the qua'ntitiesof acid zinc phosphate and boric acid mentioned above requires about 6.5 to 7 cubic centimetres of theasodium hydroxide soluti'om the increase ot'abdut'l to 1.5 cubic centimetres over the titration'fig ure obtained in the case ution alone being due to the presence of the boric acid.
- the first titration figure obtained aftermaking an allowance of aboutlto 1.5 cubic centimetres-forthe boricv acid present, measures approximately the amount of acid fzinc I and'the second figure obtained (13 cubic centimetres for the fresh bath) measures approximately the amount-of-borie acid pres--' .ent.
