Title: Sodium iodide reaction
Post by: samrow on October 24, 2004, 04:08:39 PM

Can any one help me with the completition of this equation please?!?!

When sodium thiosulphate reacts with an iodide solution, i have calcualted the molarity ratio at 3:2

but how can i complete the formula with the products so it also balances out??

Thanks for looking!

2Na2S2O3 + I2 = Na2S4O6 + 2NaI
sodium thiosulfate reacts with IODINE solution in ratio 2:1
