Can phosphate affect pH?

Phosphate (PO4) is actually a salt derived from the weak acid H3PO4 this negative ion (PO4_) will bond with pos ions and this process will not influence the PH! That is basicly the answer to your question And how to determin this phosphate concentration will interact with the pos ions is dependent of the Ph
