(a arrow p, t) only overset⊕NH4 will get hydrolysed (cation hydrolysis) pH <7 pH =(1/2)( p Kw- p Kb- log C) ( b arrow s , t ) It is a SA ⋅ pH =2, New conc =(10-2/10)= 10-3, pH =3 ( c arrow r ) It is a WB, so pH >7 ( d arrow p , q ) Salt of WA / WB both CH 3 COO ominus and overset⊕NH 4 will hydrolysed so both cationic and anionic hydrolysis
