When nitric acid HNO3 is neutralized by sodium hydroxide NaOH the byproduct is H2O and NaHO3. Lets say you mix one pound of each what would be the amount in weight of the H2O and the NaHO3?
Our company uses an in-house mixed Non-chromated De-oxidizer. The percentages are fairly simple but duplicating the formula for the initial charge is posing a problem. The person who created the mix in the first place has retired and left for places unknown.
It is:
H2SO4 5-10%
HNO3 5-10%...

What are the requirements for salt used in salt fog testing (such as sodium chloride purity and trace elements in the salt?)?
What are the requirements for the water used (is RO water good enough or is DI water required?)?
I need some advice. We are trying to Bright Dip and Clear Anodize 2011 aluminum and get consistent brightness and color. Our Bright Dip solution is at optimum pH, specific gravity, and temperature but it is still hit and miss. Some time it is bright and some time it is very frosted. I think...
The question has come up at what side on a chromate conversion coated panel should be evaluated after ASTM B-117-3 salt fog testing. The panels are required to tilt at a 6 degree angle. The front side is exposed to precipitating salt fog that runs down the face where as the back side is only...
