Parson's brand Household
ammonia is 3% ammonium hydroxide.
1
This means that a w/w solution is ~ 3 gms per
100 ml solution.
This also means that 10ml (2 teaspoonsful) has 0.3 gm ammonia.
If we dilute the two teaspoonsful of household ammonia in one quart (~1000ml) of RO water and mix it well with a plastic spoon, it will have a strength of 0.003 gms per
10ml (2 teaspoonsful, close enough for home measurements).
If we take ten (10 ML= 2 teaspoonsful) OF THIS FIRST DILUTION and dilute it again to 1000ml, our final dilution would be
3 PPM. Mix well with a plastic spoon, then test the final solution to see what value you get for the result. If your test kit is good, and yur technique is correct, then you shuld get a value in the vicinity of 3PPM.
If you can google the mnufacturer of your particular brand, you can probably find out exactly what the strength of the ammonia actually is, most test kits will measure a minimum of 0.5 PPM and range up to 8 to 10 PPM. Most Household ammonia is 5% or so, but may be as high as 10% w/w. !0% is usually called janitorial stremgth, and will take your breath away from 3 feet. Properly dispose of the solutions by flushing them down the commode, being careful nt to splash the soutin ut n the floor or in yur eyes. (see the MSDS below in the footnotes). Make sure to wash and rinse your hands with plenty of water when finished.
