Expert Answer:

See

For a base,

equivalent mass = Molecular mass / acidity

For an acid,

equivalent mass = Molecular mass / acidity

 

Example: Equivalent mass of NaOH:

Its acidity is 1 since it has one OH- ions.

So, its equivalent mass = Molecular mass

 

Example: Equivalent mass of Ba(OH)2:

Its acidity is 2 since it has 2 OH- ions.

So, its equivalent mass = Molecular mass / 2

 

Example: Equivalent mass of HCl:

Its basicity is 1 since it has one H+ ions.

So, its equivalent mass = Molecular mass / 1

 

Example: Equivalent mass of H2SO4:

Its acidity is 2 since it has two H+ ions.

So, its equivalent mass = Molecular mass /2
