Rates of Ammonia Absorption and Release in Calcium

After synthesis, ammonia can be selectively absorbed by calcium chloride; nitrogen and hydrogen are not absorbed. The kinetics of release seem to be diffusion controlled. The kinetics of absorption are consistent with a first-order reaction after an initial period of a higher-order reaction, which may indie a nucleation event. At 225 °C, both absorption and release show half-lives of

Calcium - Infogalactic: the planetary knowledge core

In chemical terms, calcium is reactive and soft for a metal; though harder than lead, it can be cut with a knife with difficulty.It is a silvery metallic element that must be extracted by electrolysis from a fused salt like calcium chloride. Once produced, it rapidly forms a gray-white coating of calcium oxide and calcium nitride for reacting with the oxygen and nitrogen in the air when

Polyphosphates are used in the drinking water to prevent the precipitation of ions such as calcium and iron. The possible negative impact of using polyphosphates is the undesirable complexation of lead which could result in elevated lead levels in consumer’s tap water. Although the water industry has focused on complexation, lead polyphosphate solids such as lead pyrophosphate, Pb2P2O7
