Answer:
[OH-] = 4 x 10^-2 M is basic.
Explanation:
* pH is a measure of hydrogen ion concentration ([H+]) in a solution.
* pOH is a measure of hydroxide ion concentration ([OH-]) in a solution.
* Neutral solutions have equal concentrations of H+ and OH-.
* Acidic solutions have a higher concentration of H+ ions than OH- ions.
* Basic solutions have a higher concentration of OH- ions than H+ ions.
Since [OH-] is 4 x 10^-2 M, which is significantly greater than the concentration of OH- in a neutral solution (1 x 10^-7 M), the solution is basic.
