Dear All,

Kindly tell me if QAC's eg, Benzalkonium chlorides
(cations) can be stable in acidic conditions of pH
about 3-5 and if they would react with sodium
pyrophosphate NaP2O7 or sodium acid pyrophosphate
Na2H2P2O7 ?
Can free Dil HCl be used to regulate the pH to 3-4 ?
Thanks in advance,
jmarjorie
