The acidity of a solution is measured by its pH. If (T*] represents the concentration of hydrogen ions (in moles/liter) in the solution, the pH is defined by pH = – log Ht || Suppose a solution has pH = 1.98.

. So, we need 5.00 mmol of base (titrant) to be delivered to the analyte. Since we know the molarity of the base and moles of base, we just need to solve for the volume of base (titrant) to be added. molpase Mpase = Voladded Molarity base =. 0.150 (M) Moles of base = _5.00 (mmol) Volume of base needed to reach equivalence point _ (mL)
