Tricalcium Phosphate (TCP)
Tricalcium phosphate, TCP (CAS 7758-87-4), is a very fine insoluble powder with a high specific surface area. That surface area is what makes it one of the most effective anticaking agents available for hygroscopic powders.
Manganese Sulfate
Manganese sulfate (CAS 7785-87-7) supplies manganese, an essential micronutrient required in the photosynthetic complex that splits water. Deficiency shows as interveinal chlorosis on young leaves, unlike magnesium deficiency.
Magnesium Sulfate
Magnesium sulfate, Epsom salt as the heptahydrate (CAS 10034-99-8), is the cheapest soluble magnesium source. Grade is selected by hydration state, since the heptahydrate and the monohydrate differ substantially in magnesium content.
Zinc Sulfate
Zinc sulfate (CAS 7733-02-0) supplies zinc, the micronutrient most often deficient in cereals worldwide. Zinc availability collapses on alkaline and high-phosphate soils, which is where correction is usually needed.
Ammonium Sulfate
Ammonium sulfate (CAS 7783-20-2) is a 21-0-0 fertiliser that supplies sulphur alongside nitrogen. Its acidifying reaction in soil is a genuine agronomic tool on alkaline ground and a drawback on already acid soils.
Copper Sulfate
Copper sulfate pentahydrate (CAS 7758-99-8) is the bright blue crystalline copper salt. It is an algaecide, a fungicide and the copper source in Bordeaux mixture, and it is highly toxic to fish and aquatic invertebrates.
Sodium Sulfate Anhydrous
Sodium sulfate anhydrous (CAS 7757-82-6) is a chemically inert, non-hygroscopic white powder. It is used in enormous volume as a detergent filler and, in textile dyeing, to drive dye onto the fibre rather than leave it in the bath.
Sodium Bisulfate
Sodium bisulfate (CAS 7681-38-1) is a dry acid: a solid salt that dissolves to give a strongly acidic solution near pH 1. It replaces liquid mineral acid wherever handling concentrated acid is the thing to avoid.
Alum
Alum, aluminium sulfate (CAS 10043-01-3), is the classic coagulant of municipal water treatment. Dosed into raw water it hydrolyses to aluminium hydroxide floc, which sweeps suspended solids and colour out of suspension.
Ferrous Sulfate
Ferrous sulfate (CAS 7720-78-7) is iron in the reduced divalent state, which is what makes it useful. It reduces hexavalent chromium in cement to the harmless trivalent form, preventing chromate contact dermatitis in workers.
Sodium Metabisulfite
Sodium metabisulfite (CAS 7681-57-4) is the solid, more stable and more concentrated form of the bisulfite chemistry. It is preferred where a dry material is easier to ship and store than a bulk sulfite solution.
Sodium Thiosulfate
Sodium thiosulfate (CAS 7772-98-7) is the classic photographic fixer, hypo, and a fast dechlorinating agent. It also reacts with cyanide to form far less toxic thiocyanate, which is the basis of its medical use as an antidote.
Sodium Sulfite Anhydrous
Sodium sulfite anhydrous (CAS 7757-83-7) is the neutral-to-alkaline member of the sulfite family. It scavenges oxygen without driving pH down, which is why it is the boiler feedwater choice where acidity would corrode.
Sodium Bisulfite
Sodium bisulfite (CAS 7631-90-5) is a reducing agent and oxygen scavenger, supplied as a solution or solid. Its largest single use is dechlorinating water ahead of reverse osmosis membranes, which chlorine destroys.
Potassium Nitrate
Potassium nitrate (CAS 7757-79-1), traditionally saltpetre, is a 13-0-46 fertiliser carrying potassium with no chloride. That matters for chloride-sensitive crops such as tobacco, grapes, potatoes and most fruit.
Ammonium Nitrate
Ammonium nitrate (CAS 6484-52-2) is a 34-0-0 nitrogen fertiliser supplying nitrate and ammonium nitrogen together. It is a strong oxidiser and a security-controlled substance in most jurisdictions, so supply is regulated.
Sodium Nitrate
Sodium nitrate (CAS 7631-99-4), historically Chile saltpetre, was the world's original nitrogen fertiliser before synthetic ammonia. It remains in use as a fast-acting nitrate source and as a component of molten heat-transfer salts.
Calcium Nitrate
Calcium nitrate (CAS 10124-37-5) is the only common fertiliser supplying calcium in fully water-soluble form. It is the standard remedy for blossom end rot and tip burn, which are calcium-transport rather than calcium-supply failures.
Magnesium Nitrate
Magnesium nitrate (CAS 10377-60-3) supplies magnesium in fully soluble nitrate form. Magnesium sits at the centre of the chlorophyll molecule, so a deficiency shows directly as interveinal yellowing on older leaves.
Sodium Nitrite
Sodium nitrite (CAS 7632-00-0) is the nitrite rather than nitrate salt, and the difference is chemically large. It is a reducing and diazotising agent, a potent corrosion inhibitor, and acutely toxic at low doses.
