What is the n factor of SO2 molecule and equivalent weight of Sulphur in SO2

Answer :;

For acids, n-factor is defined as the number of H+ ions replaced by 1 mole of acid in a reaction. Note that the n-factor for acid is not equal to its basicity; i.e. the number of moles of replaceable H+ atoms present in one mole of acid.

S + O → SO2 [n-factor for SO2 = 4].

<sub>The Equivalent weight of Sulphur in SO2 is 8
