Polyphosphoric acid 86%

Jan 21, 2020Polyphosphoric acids are odourless, high viscousity liquids with strong hygroscopic properties. Phosphoric acids with 95% H3PO4 (68% P2O5) contain the simple orthophosphoric acid. At higher concentrations the acid consists of a mixture of ortho, pyro, tri, tetra and highly condensed phosphoric acids. For this reason acids with a concentration gt; 68% P2O5nbsp;are commonly Get price

Molarity

Dilution of Solutions. Dilution is the process whereby the concentration of a solution is lessened by the addition of solvent. For example, we might say that a glass of iced tea becomes increasingly diluted as the ice melts. The water from the melting ice increases the volume of the solvent (water) and the overall volume of the solution (iced tea), thereby reducing the relative concentrations Get price

The Principles of pH

To lower pH, brewers often add calcium ions, from gypsum (calcium sulfate) or calcium chloride. In a 5-gallon (19-L) batch, one or two teaspoons of either of these will often solve the problem. Likewise, organic acids — such as lactic acid or phosphoric acid — can be added to directly lower mash pH. Get price
