Question

what is the equivalent weight of citric acid

Answer 1

The equivalent weight of citric acid ($C_6H_8O_7$) is 64.4 g.

• Equivalent weight can be calculated by the formula,

        E = molecular weight/ basicity

• The molecular weight of citric acid ($C_6H_8O_7$) is 192.12 g/mol
• Also citric acid is a weak base and the basicity of citric acid is 3.
• So we can easily calculate the equivalent weight of citric acid by putting the following data in the known formula,

        E = 192.12/3

            = 64.4 g.

So, we can conclude that the equivalent weight of citric acid ($C_6H_8O_7$) is 64.4 g.
