    I agree with you ChrisJ. Chloramine is different chemical comp than chloride and this is what the municipality is using to treat the water in the town where my one pipe steam system lives.

    I confess to knowing very little on water chemistry, in fact I flunked chem. in college and had to go to summer school. You guys know your stuff very impressive.

    I just drained my Smith G8-3 boiler today after having added one steam master tablet two years ago. The water was a bit cloudy with the violet hue; i saw no evidence of rust in the water so i would say they are doing the job.

    I refilled the boiler and added one steam master tablet, I'm bringing the system up to steam as I type. I have no idea about what the nitrate levels in the water are but with no visible signs of corrosion I would say the boiler is protected.

    If you mix a tiny amount of a base, such as sodium hydroxide, in a cup of water, it will probably ionize completely and give you a very basic solution. Similarly, if you put a tiny amount of acid in a cup of water. Impractical to measure such small amounts.

    What photographers who mix their own stuff do in such cases is to mix up a percentage solution. Put one gram (about the smallest amount you can measure with any accuracy) of the stuff in 100 grams of water and you have a percentage solution. Then 1 gram of the solution is 1/100 of a gram of the original substance, and you can measure that pretty well.
