Find total number of reagents which can produce I2 from KI solution. Conc. H2SO4, Hg(NO3)2 solution, — Reaction Mechanism Chemistry Question
Question
Find total number of reagents which can produce I2 from KI solution. Conc. H2SO4, Hg(NO3)2 solution, CuSO4 solution, Conc. H3PO4, K2Cr2O7/H+, Cl2 water, Pb(CH3COO)2 solution, Ca(OCl)Cl/H+, NaNO2 + dil. HCl
Answer: **6** / CONC. H2SO4 + 2KI -> K2SO4 + HI + 1/2 I2↑. HG(NO3)2 + 2KI -> HGI2↓ + 2KNO3. CUSO4 + KI -> CU2I2↓ + K2SO4 + I2. CR2O7^2-/H+ + KI -> CR3+ + I2. PB(CH3COO)2 + KI -> PBI2↓ + CH3COOK. CA(OCL)CL + KI -> CACL2 + I2. NANO2 + DIL. HCL + KI -> KCL + NACL + NO + I2. (CONC. H3PO4 + KI -> NO OBS.)
