Question

Can somebody calculate the weight of NaOH required to prepare 2000mL of a decinormal solution??? Thank youuuuuuu

Answer 1

ANSWER

For hydrated oxalic acid, (COOH)

2

.2H

2

O, molar mass is 126 g/mol.

Equivalent weight =

2

M

=63

Meq. of oxalic acid =500×0.1=50

E×1000

w

=50

w=

2

126

×50×1000=3.15 g

Hence, mass of oxalic acid required is 3.15 g
