<h3>What is pH of a Solution?</h3>
pH is the measurement of how acidic or basic a solution is. The range of pH values is from 0 to 14. Lower pH values mean higher acidity, while higher pH means higher basicity. If the pH value is equal to 7, then the solution is neutral.
To calculate the pH of the solution, a few approaches are possible. Here, the pOH of the solution is calculated first using the molar concentration of ions. Because pH + pOH = 14, the pH of the solution can then be calculated by subtracting pOH from 14.
Because 2 moles of ions are formed per mole of
dissolved, the pOH of a saturated
solution at
is,
Concentration () of
ions,
= 0.02335 mol
/L X 2 mol
/1 mol
= 0.0467 mol
/L
*pOH of saturated solution,
pOH = -log []
pOH = -log [0.0467 mol /L ]
pOH = 1.33
*pH of saturated solution,
pH = 14 - 1.33
pH = 12.67
Hence, the pH of the solutions is 12.67.
