Solve this: tynsiciiy salt is Y (replaceable
is (total charge on cation)
Solution
: of on molecule is zero
A' and positive integers. Therefore,
then X-2
Y —3 then X
2
Y-2 and .V-2
Therefore basicity of salt is 2 and its acidity is 4.
(v) Equivalent mass of basic salt :
Molar nuss of basic salt
Eq, mass of basic salt
Replaceable OH gps in basic
...00)
A basic salt is one which has replaceable OH gpseg,
etc.
EXAMPLE 21 Calculate equivalent mass of (a) NaH2P04,
and (b) Na:HP04.
Solution ENaH
Na:HP04
(Two H are replaceable)
(One H is replaceable)
EXAMPLE 22 Calculate equivalent mass of
H2S04. NaH2P04 and in the reaction :
