text: By concentrated phosphoric acid is meant an acid whose concentration, expressed as P 2 ° 5 (weight) depending on the use of phosphaters, is between about 50 and about 60% (except when otherwise specified, the zeros are not considered significant figures).
text: When switching to a commercial acid, that is to say having from 50 to 54% in P-, 0 -, the solubility in calcium sulphate expressed in the same way goes to a value between 0.4 and 0.9%, which means that a significant part of the calcium sulphate present in phosphoric acid at 30% will be precipitated after its production, ie approximately 25 to 50 kg of solid per tonne of P 2 ° 5 '
