To calculate the concentration of a solution using acid–base titration data. In an acid–base titration, an acid (or base) of known concentration is added to a base (or acid) of unknown concentration until the number of moles of H+ and OH- are equal, a condition called the equivalence point. Since you know the number of moles of H+ (or OH- ) that you added, you can determine the number of moles of OH- (or H+) in the unknown solution. For...

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. Start Virtual...
