In the problem below identify each substance as a weak acid,strong acid,weak base,strong base both weak acid and weak base or neither acid or base
a) NH3 : weak base
b) HCNO : weak acid
C) HClO :weak acid
d) Ba(OH)2 : strong base
explanation : There are six common stron acids HNO3,HClO4,H2SO4,HCL,HBr,HI and strong base are all the group Ist hydroxides and the Three of group 2 hydroxides Ca(OH)2, Sr(OH)2 and Ba(OH)2.
Now identify conjugate base or conjugate acid for the weak acid or base
a) NH3 : conjugate acid is NH4+
b) HCNO : conjugate base is CNO-
C) HClO : conjugate base is ClO-
a) NH3 is a base which means it has capacity to accept the hydogen ion so if it accepts a hydrgen ion it will become NH4+ ion which is an acid since it now can donate a hydrogen ion but it a conjugate acid to base NH3 since it is formed from NH3 after accepting a hydrogen ion.
b) HCNO is an acid so it will donate hydrogen ion and will form CNO- as CNO- can now accept a Hydrogen ion is a base but it is a conjugate base to HCNO since it is formed from HCNO by donating a hydrogen ion.
