Question

In an acidic solution, permanganate ion reacts with tin(II) ion to give manganese(II) lon and tin(IV) ion. (a) Enter a balanced net ionic equation for the reaction (include physical states in your answer). 2+ 2+ 4+ 2MnO& (aq) + 5Sn (aq)+16H (aq)-2Mn (aq) + 5Sn (ag)+8H O) Save & Close Undo Select Erase Help 7 8 (aq) (g) () (s) 4 5 6 e + E NONE 1 2 C F NR Na Mg Al Si P CI K Ca Ba Cr Mn Fe Cu Zn Br (b) How many milliliters of 0.294 M potassium permanganate solution are needed to react completely with 36.1 mL of 0.103 M tin(II) chloride solution? mL KMnO4 the tolerance is +/-2% O z 1 H\

Answer 1

Let lloleme of Potassicom Permanganate leequired is ome). Millionoles of K Monoy = Molarity x volceme of Solution (en med = (0.294)(0) Millimoles of tion (11) = 0.103)/36-1)= 3.72 from reaction, moles of Moroy leequires 5 moles of S.924. -0.294 (16) 294) () millimoles of Son $ (0.294)(v) = 3.72 v=5.06 me &
