Ammonia, NH 3, is an alkaline gas and so turns damp red litmus paper blue. Ammonium ions (NH 4 +) – found in ammonium compounds such as ammonium chloride, ammonium nitrate and ammonium sulfate ...
"You won't just find ammonium nitrate in the ground," explains Andrea Sella, professor of chemistry at University College London. That's because it's synthetic, made by reacting ammonia with ...
This material appears to be rich in ammonium, a type of ammonia with an extra hydrogen ion. Scientists had previously figured ...
The addition of NH4Cl to a solution of ammonia shows the effect of adding a common ion to a system at equilibrium. Add water to each of two beakers. Add 2 drops of phenolphthalein to each. Add a few ...
Complexes and preipitates of nickel (II) are formed by adding ammonium hydroxide, ethylenediamine ... Nickel salts are poisonous if ingested. Ammonia and ethylenediamine are caustic and irritating to ...
The equation shows that ammonium chloride (a white solid) can break down to form ammonia and hydrogen chloride. It also shows that ammonia and hydrogen chloride (colourless gases) can react to ...
