What is the solubility of #NH_3# in 100 g of water at a temperature of 20°C?
The commercial product ammonium hydroxide (or more correctly saturated aqueous ammonia), is approx,
If you have the density available, you can solve for the aqueous concentration, and you get approx.
Look at videos of the ammonia fountain on the web; there should be some good ones. I would post one here, but my google fu is weak, and I would not attribute it correctly.
