| Abstract: | Through the comparison between the results of titration in standard substance and C-glass batch using bromocresol green -methyl red indicator and methyl orange indicator separately,it was demonstrated that the methyl orange indicator formerly used for determining soda ash in glass batch could be changed to bromocresol green-methyl red indicator,and this could increase the accuracy and precision of the test. |
