KClO3 from NaClO and KCl

3NaClO + KCl = KClO3 + 3NaCl

The masses of the individual elements are:

Na = 23
K = 39.1
Cl = 35.5
O = 16

Total atomic mass of reactants = 298.1
Relative mass of NaClO = 74.5 * 3 = 223.5
Relative mass of KCl = 74.6

Total atomic mass of reactants = 298.1
Relative mass of KClO3 = 122.6
Relative mass of NaCl = 58.5 * 3 = 175.5

the ratio of NaClO to KCl required is 75% to 25% gives 41% KClO3 and 59% NaCl

1 liter Bleach = 30.00 gram NaClO and 10 gram KCl = 16.4 gram KClO3 and 23.6 gram NaCl

I think this would work better if you first preformed thermal decomposition on the NaClO. This would form 1 mole of NaClO<sub>3</sub> and 2 moles of NaCl. You then preform the double replacement to form KClO<sub>3</sub> and another mole of NaCl. You may end up with NaCl, KClO, KCl, and NaClO all in equilibrium if you just mixed them together.

I know for a fact this method works. I carried it out over the weekend. I did get most horrible yields though. Something like 52%. It also seems that you have fairly weak bleach. 30 grams per liter is something like 3%. Are the yields better with the lower concentration? 6% is commonly available here.

sorry, i have just one question , it doesn't heve nothing to with this topic but i didn't want to make a new one for some stupid thing . my question is what salt is used in dishwashers , i know it isn't NaCl but what is it than ???? thanks
