[QUOTE="mimi88, post: 6033418, member: 645207"] [h2]Homework Statement [/h2] The ratio of KMnO4 to I2 is given by 2 MnO4 - + 16 H+ + 10 I - ⇌ 2 Mn2+ + 5 I2 + 8 H2O the ratio is 2:5 - The ratio of I2 to S2O3 2- is given by 1 I2 + 2 S2O32- ⇌ 2 I-+ S4O5 2- the ratio is 1:2 therefore n(S2O3 2- ) = n(MnO4 - ) x 5 [h2]Homework Equations[/h2] Why the mole of (S2O3 2-) is equal to mol of ( MnO4-) times 5?? Where is the 5 come from? What is the relationship between (S2O3 2- ) and ( MnO4-)? Please help me, thanks. [/QUOTE]
