Arrange the following aqueous solutions, all at 25 C, in order of decreasing acidity.
Rank from most acidic to most basic. To rank items as equivalent, overlap them
pH=5.45, pOH=8.55, 0.0023 M HCl, 0.0018 M KOH
Homework Answers
pH of 0.0018M KOH : 14-2.74 =11.25
so, most acidic is 0.0023M hcl as pH is less than others
the order is
0.0023M hcl , pH = pOH , 0.0018 M KOH
