What is the pH of a solution containing 3.0*10-4 mg/L of OH- at 25oC?


Expert Answer

Step 1

We have to calculate the pH of the solution whose OH- concentration is given as 3.0×10-4 mg/L at 25oC.

Step 2

pH measures the acidity of the solution whereas pOH measures the basicity of the solution.

pH log H РОН 3-1og [OH ] And the relation between the pH and pOH is рH +рОН %3D 14

Step 3

Using the concentration of hydroxide ion, cal...
