Chlorine Dioxide Generation from 3 solutions?

Using a 25% Sodium Chlorite solution with a 15% Sodium Hypochlorite solution and a 31% Muriatic Acid solution (HCL) to generate Chlorine Dioxide. I have 3 different strengths of solutions to produce chlorine dioxide. Do I have to account for the 3 different strengths when I write out my chemical eqaution?

Reaction:

2NaClO2 + NaOCl + 2HCL yields 2ClO2 + 3NaCl + H20 (correct??)

181 mw + 74.5mw + 73 mw yields 125 mw + 175.5 mw

328.5 = 328.5

55% Sodium Chlorite, 23% Chlorine, 22% Muriatic Acid yields 41% C Dioxide, 53% NaCl, 6% H20 (correct)

50 gals of Sodium Chlorite, plus (50x0.23) to get 11.5 gals of Hypo plus(50x0.22) to get 11 gals of HCL to yield 41% of the Chlorine Dioxide gas from the total reaction? Do I have to take in to account the % of each solution? Do I have to adjust the stochiometric equation ?

25% Sodium Chlorite = 10.59 lbs/gal

15% Hypo = 10.42 lbs gal

HCL (muriatic acid) = 9.67 lbs/gal

Answer 1

2NaClO2 + NaOCl + 2HCL -->>2ClO2 + 3NaCl + H20

Solutions of known concentration can be prepared either by dissolving a known mass of solute in a solvent and diluting to a desired final volume or by diluting the appropriate volume of a more concentrated solution (a stock solution) to the desired final volume.
