Swim has a solution containing only h3po3 and water. The label indicates: "Available phosphate(p2o5) 35%, Derived from: Phosphorous Acid", also says "This product contains no less than 5.1 lbs of h3po3 per gallon" It is a one gallon bottle with a net weight of 12.58 lbs.
I have done extensive reading and searching on h3po3 + I2 reduction but swims left with the following questions:
What is the preferred solution percentage used in this reduction? I have read that beez are using h3po3 = to h20. I assume that is in pure form so is this a 50% mixture solution?
Swim believes he has a 35% solution, what would be the recomended way to concentrate this solution without oxidizing it into h3po4?
Will the reduction work with current 35% solution if I compensate by increasing the ratios of h3po2/I2?
Swim is ready to dream about this very soon and was going to use 10g E(hcl) + 10g I2 + 25-30 mls of h3po3 solution (35%), relux for approx 4 hrs @ 120-130 degrees C. Does anyone forsee a problem with this? Should I concentrate the solution first?
Thanks for your assistance in keeping my dream from becoming a nightmare.
