Today we also discuss How to Check Normality of 0.1N NaOH?

The formula  is the weight of the substance in grams

The = Normality x Equivalent weight of the substance x given volume in liter

W= 0.1 x 40x 1

= 4.00gm (NaOH is to be dissolved in one liter of distilled water)

How to Check Normality of 0.1N NaOH

  • The equivalent weight of NaOH is 40.00gms

sum of atomic weight of Na (23gm) + oxygen(16gm) + Hydrogen (1.00gm)


Element                            Atomic mass                                Atoms


Sodium                                          22.989770                                          1

Hydrogen                                    1.00794                                               1

Oxygen                                         15.9994                                                1
