The pH of an aqueous solution is 4. a)The pOH of this solution ___. b)[H^+] is ___(scientific notation)=___(demical notation) c)[OH^-] is ___ (scientific notation) d) Is this solution acidic or basic?
pH and pOH are values derived from the concentration of either [H+] or [OH-] which generally describe the acidity or basicity of the solution. It is the -log of the concentration of H+ and OH- present in the solution. The sum of pH and pOH is equivalent to 14.
We can summarize the relationship as follows:
pH > 7 basic
