Phosphoric Acid 75% Dosage Rate Help Needed?

[Saisonator]

Hi, I wondered if anybody has the dosage rates for removing alkalinity CaCO3, using 75% Phosphoric Acid.
Thanks

I think from Bru'n Water 0.1ml/L removes about 60ppm alkalinity.

If you have the KH test kit it might be worth testing that to confirm.

Thanks Steve, I will try reducing my 170 ppm water with 0.2ml/L phosphoric acid. Will do a 5 Litre sample with 1 ml of phosphoric acid and see what I get.

I will be using Brewers Friend water calculator so this is really just to test my acid and confirm it is of an accurate concentration.

I don't know if this will be of any help here, but at somewhere right near 73.5% concentration, Phosphoric Acid can quite effectively use data commonly seen for 88% Lactic Acid. At 75% you are not far off from this.

Likewise, Phosphoric Acid at 68% can utilize data seen for 80% Lactic Acid.

Thanks that roughly tallies up with Steves 0.1ml/L removing 60ppm.
