Assuming equal concentrations, rank these solutions by ph.? assuming equal concentrations, rank these solutions by ph. koh (aq hcn (aq

I remember coming across this question and the options were:

KOH, HCN, NH₃, HI, Sr (OH) ₂

Now, a substance with a low pH is one that dissociates completely in water to release hydrogen ions, while basic substances dissociate completely to release hydroxide ions. Therefore, in the order of increasing pH:

HI, HCN, NH₃, Sr (OH) ₂, KOH
