The only place that I can find that sells food grade lactic acid is Grain & Grape @ 88% in 250ml lots.
Using the 250ml as an example how much distilled water needs to be added to dilute from an 88% to 80% solution (80% seems to be what some brewers are using as a pH additive).
Perhaps you would be able to give me the formula with the 250ml example.
Apparently 88% lactic acid, means that 88g of 100g solution is lactic acid & is known as weight / weight (w/w) percentage. Because the density of lactic acid is higher than water, 100 ml weighs 120g.
Thank you for your help.
