R-0870

[Stargate_to_earth]

So I have some r 0871 some r 0001 and some r 0002.

I've been told that r 0001 + r 0002 = r 0870...

Any truth to this?

 

[jblizzle]

I have never heard that and doubt it very much.

Um, R-0870 is a powder. 0001 and 0002 are liquids.

Liquid + Liquid = Powder?

Went pink after 5 drops of each of reagent 1 and 2 went back clear after 24 drops of 871 in 10 ml sample

R-0001 plus R-0002 should be roughly equivalent to R-0870. They are both dpd reagent that creates the colored sample.

The difference is how the concentration of chlorine is determined. One uses a color match while the other titrates the chlorine with a reducing agent.

Using powder dpd for color matching probably wouldn't give good results due to needing exact dpd amounts for good color results.

I think that using the liquid reagents with a titration should be reasonably accurate.

In any case, I would use the correct reagents for the tests.

I've got the powder coming in the mail, was a stopgap measure

got the powder now, may do an experiment to see how closely it matches...
