Answer 2

Four moles of KMnO4 react with an excess of hypo solution to produce two moles of Na2SO4

Explanation:

$4 KMnO4+Na2S2O3. 5H2O ------- 2 Na2SO4+2 K2SO4+MnO2$

• When potassium permanganate reacts  with sodium thiosulfate, it gives sodium sulfate, potassium sulfate and insoluble manganese dioxide.
• This reaction is in strong acidic solution where permanganate is reduced to manganese ions and then thiosulfate gets oxidized to sulfate.
• This reaction is a redox reaction in which the  manganese in permanganate ion gets reduced to Mn2+
• Sulfur in thiosulfate will get oxidized to form the sulfate ion, SO4-
• Oxidation state of Manganese goes from +7 to +2,  whereas oxidation state of sulfur goes from +2 to +6.
