pKa measurement

Hi everyone,
we are formulating some chemical peels using salicylic acid and lactic acid . These are only sold in professional clinics.
One of our clinics asked to know the pKa of our peels.
We have the pH set at 2.00 - 3.00.
Can someone please help out how to measure the pka from pH?

TIA

  • pKa is mathematically derived from the Ka, or the acid dissociation constant. It doesn't make any sense for your overall formulation to have a pKa, since that is used to describe the strength of a single acid in solution. There may be a miscommunication as to what information they want about your formula.
