To prepare 250 ml of m/20 oxalic acid solution

Answered by admin @ 23/08/2021

Molecular formula of solid crystalline oxalic acid: H2C2O4, 2H2O. Its Molecular Wt. 126. Hence, to prepare 250 ml M/20 oxalic acid solution 126*250/(20*1000) = 1.575 gram of oxalic acid is to be dissolved in water in a 250 ml volumetric flask.

thanks for the great opportunity to answer friend....
