6-8: Acid-Base Titration: Practice Titrations provide a method of quantitatively measuring the concentration of an unknown solution. In an acid-base titration, this is done by delivering a titrant of known concentration into an analyte of known Although in this case you know the concentration of both NaOH and HCI, this will give you practice in performing a titration and calculating the concentration of the analyte, which in this case is HCI. 1.
