Ionic Equation Problems, Please Help
« on: July 11, 2006, 02:31:34 AM »
Hello, at the moment I am having some serious problems with this net ionic eqation my prof gave us. I was wondering if anyone could help out with it? The problem is as follows;
50 Ml of 0.1M solution of NaNO2 is added to 50 Ml of 0.05M solution of K2Cr2O7
how many grams of KNO3 can be produced?
I only have a few hours to finish it, so even a brief reply would be greatly appreciated. Thank you

this is a redox problem.

work out the chemical equation based on this:
potassium dichromate oxidises sodium nitrite to sodium nitrate while itself is reduces to chromium(III)

Once you have reaction equation it is a simple limiting reagent question.
