Calculate the hydrolysis constant of the salt containing NO_(2)^(-) ions. (Given K_(a) for HNO_(2) = 4.5 xx 10^(-10)).

Calculate the hydrolysis constant of the salt containing NO_(2)^(-) io

1.	Calculate the hydrolysis constant of the salt containing NO_(2)^(-) ions. (Given K_(a) for HNO_(2) = 4.5 xx 10^(-10)).
Answer» Solution :For the SALT containing `NO_(2)^(-)`ION (i.e., salt of weak acid), `K_(b) = (K_(w))/(K_(a))=(10^(-4))/(4.5xx10^(-10))=2.2xx10^(-5)`.
