5 NaClO2 + 4 HCl = 5 NaCl + 4 ClO2 + 2 H2O
This is the equilibrium equation.
But lets say I don't have 4 moles of HCI say I have .1 /mole/g of HCI how much of NACLO2 do I need to produce 250 milligrams of CIO2.

I can not change the HCI has this is the amount of HCI found in the Stomach, so how NACIO2 is needed to produce 250 milligram of CIO2.

In essence what I am saying the Mole unit is to big what do I have to do milligrams of product ClO2 = 67.4518 g/mol the above equilibrium equation would produce 269.8072 g/mol I need 1000 times less product.

Your question doesn't make much sense...

You're looking for the amount of NaClO2 from the amount of ClO2?

Why are you looking for this particular amount of product if you have limiting reactant of HCl, since this is what seems to bother you?

The equilibrium equation tells you the relative amounts of the reactants and products, not the actual amounts. To solve this problem you only need to calculate the number of moles in 250 mg of ClO2 from its molecular weight (0.25/67.4518=0.0037). For every mole of ClO2 produced, you need 5/4 moles of NaClO2 from which you calculate how many mg are needed from its molecular weight. So you will need 1.25 x 0.0037 moles of NaClO2. You don't have to worry about HCl since the stomach has plenty of it and this will ensure that the reaction goes to completion.

5 NaClO2 + 4 HCl = 5 NaCl + 4 ClO2 + 2 H2O

What you really need is a correctly balanced equation.
This one isn't.

Really? How would you correct it?
 Unknown008 Posts: 8,147, Reputation: 3745 Uber Member #6 Aug 2, 2012, 09:41 PM
Huh?

On the left:
5 Na
5+4 Cl
10 O
4 H

On the right:
5 Na
5+4 Cl
8+2 O
4 H

It seems balanced enough for me...

I was mistaken. It is balanced correctly.

Bah well, the OP hasn't come back to clarify their question.

DrBob1,

I was curious about the implied internal use of NaClO2. It is the active ingredient of Miracle Mineral Solution which is used to purify water, and claimed to kill viruses and cure sundry diseases. Valid home remedy or snake oil?
