Under no circumstances should you use 5.2. Not in you mash, not in your sparge, not in your beer, period.

5.2 is a mixture of monobasic (mostly) and a bit of dibasic sodium phosphate. It forms a buffer, but not a good one, at pH close to 6 (I think I got 5.8 or so in DI water) but the buffering capacity is poor. So yes, the acidic phosphate salts will pull the pH down a bit but why not just use phosphoric acid and save yourself having to live with the sodium?
