The explosion resulted from the detonation of tonnes of ammonium nitrate, a combustible chemical compound commonly used in agriculture as a high nitrate fertilizer, but which can also be used to manufacture explosives. Why did the ammonium nitrate explode in Beirut? Q: What likely happened in Beirut? A: According toRead More →
Quats (quaternary ammonium compounds) are potent disinfectant chemicals commonly found in disinfectant wipes, sprays and other household cleaners that are designed to kill germs. It is often the stuff that allows a product to claim to be antibacterial, as they are certified by the EPA as pesticides. Is quaternary ammoniumRead More →
Ammonium nitrate is a popular fertilizer since it provides half of the N in the nitrate form and half in the ammonium form. The nitrate form moves readily with soil water to the roots, where it’s immediately available for plant uptake. Does fertilizer contain ammonium? Ammonia has the highest NRead More →
The term sublimation refers to a physical change of state and is not used to describe the transformation of a solid to a gas in a chemical reaction. For example, the dissociation on heating of solid ammonium chloride into hydrogen chloride and ammonia is not sublimation but a chemical reaction.Read More →
For many years I’ve used ammonium sulphamate as a weedkiller. It’s a very simple chemical, basically the same as sulphate of ammonia the nitrogen fertiliser but made crooked. Because it is a simple chemical the environmental effects are easy to judge. … Will ammonium sulphamate kill trees? Ammonium sulphamate (AMS)Read More →
Ammonia volatilisation: a chemical process that occurs at the soil surface when ammonium from urea or ammonium-containing fertilisers (e.g. urea) is converted to ammonia gas at high pH. Losses are minimal when fertiliser is incorporated, but can be high when fertiliser is surface-applied. What causes volatilization in soil? What causesRead More →
Ammonium heptamolybdate, (NH4)6Mo7O24, usually encountered as the tetrahydrate. Ammonium phosphomolybdate, (NH4)3PMo12O. 40. Ammonium tetrathiomolybdate, (NH4)2MoS4this chemical is used for analysis of chloride in a solution. What is the molybdate test? The molybdate water treatment test kit employs the catechol chemistry. In a mildly reducing alkaline solution, catechol reacts with hexavalentRead More →
Ammonium nitrate is used commonly in fertilizers; in pyrotechniques, herbicides, and insecticides; and in the manufacture of nitrous oxide. It is used as an absorbent for nitrogen oxides, an ingredient of freezing mixtures, an oxidizer in rocket propellants, and a nutrient for yeast and antibiotics. Why is ammonium nitrate banned?Read More →
The key difference between calcium ammonium nitrate and ammonium nitrate is that calcium ammonium nitrate contains some amount of calcium along with ammonium nitrate whereas ammonium nitrate is the nitrate salt of ammonium cation which has no calcium in it. What is ammonium nitrate fertilizer for? Ammonium nitrate is usedRead More →
