5.2 Chemical composition

**GilaMinumBeer** · 10-31-2008, 12:10 AM

As per Five Star;

"... The 5.2 stabilizer is a blend of two salts. They are neutralized versions of phosphoric acid. They are monosodium phosphate (Na H2 PO4) and disodium phosphate (Na2HPO4) in the right ratio they will form a buffer that locks the pH at 5.2..."

For anyone here that doesn't know and wants to.

He calls em brew salts tho instead of 5.2

So are you sure it is really 5.2 and not really brewing salts like gypsum
etc. ?
