Which of the following combinations in an aqueous medium will give a red colour or precipitate? — AITS & Test Series Chemistry Question

💡 Solution & Explanation

                  2 1 1 2 2 2 2 4 P x x i x i x i x i x cx            Since the first four roots are all distinct, the term  2 4 x cx   must be a product of any combination of two (not necessarily distinct) factors from the set         1 , 1 x i x i         2 2 x i       2 2 x i   . The only combinations are                 1 & 2 2 1 & 2 2 x i x i or x i x i         3 10 c i c   
