WebApr 12, 2024 · phosphoric acid, also called orthophosphoric acid, (H3PO4), the most important oxygen acid of phosphorus, used to make phosphate salts for fertilizers. It is also used in dental cements, in the preparation of albumin derivatives, and in the sugar and textile industries. It serves as an acidic, fruitlike flavouring in food products. Pure phosphoric … WebLpH50 (median lethal pH) (96h) phosphoric acid (bluegill sunfish): 3-3.25 Adult brook trout survived 5 months exposure to pH levels of 5.0 and above. Total egg production was not affected, but viability was significantly less at pH 5.0. Hatchability was significantly less at levels below pH 6.5.
