17.4: Titrations and pH Curves - Chemistry LibreTexts

WebA titration curve is a plot of some solution property versus the amount of added titrant. For acid-base titrations, solution pH is a useful property to monitor because it varies predictably with the solution composition and, therefore, may be used to monitor the titration’s progress and detect its end point. WebFor titration of strong acid with base--the same exact approach is taken to find the pH at various points along the titration curve! Sample problem: Find the pH when 12.75 mL of 0.0501 M NaOH have been added to 25.00 mL of 0.0506 M HClO 4 ! • how many moles of HClO 4 originally present? 25 mL x 0.0506 M = 1.265 mmoles
