(a) Following are the transition metal ions of 3d series: `Ti^(4+),V^(2+),Mn^(3+),Cr^(3+)` (Atomic numbers: `Ti=22,V=23,Mn=25,Cr=24`) Answer the following: (i) Which ion is most stable in an aqueous solution and why? (ii) Which ion is a strong oxidising agent and why? (iii) Which ion is colourless and why? (b) Complete the following equations: (i) `2MnO_(4)^(-)+16H^(+)+5S^(-)to` (ii) `KMnO_(4)overset(heat)to`
