4 :: What is the difference between an ion and a radical?
An ion is a specie that have no unpaired electron and is charged, either positively or negatively i.e. may be a cation or an anion. It is formed due to heterolysis of a molecule e.g HCl----> H+ + Cl-
A radical is a neutral specie having atleast one unpaired electron and is formed due to homolysis of a molecule e.g
H-H -------> H* + H*
The * shows an unpaired electron. Similarly CH3* is a radical.

15 :: Why are you using thioacetamide reagent in heavy metals test?
Thioacetamide is widely used in classical qualitative inorganic analysis as an in situ source for sulfide ions. Thus, treatment of aqueous solutions of many metal cations to a solution of thioacetamide affords the corresponding metal sulfide:
M2+ + CH3C(S)NH2 + H2O ? MS + CH3C(O)NH2 + 2 H+ (M = Ni, Pb, Cd, Hg)
Related precipitations occur for sources of soft trivalent cations (As3+, Sb3+, Bi3+) and monovalent cations (Ag+, Cu+).
