Section D: Standardization of a Solution of NaOH Watch the demonstration video to collect data and observe the titration of NaOH. In the space below, summarize the experiment. (2 points) In a 24 well tray, two drops of approximately 1 M NaOH was added to one well. One drop of the BTB indicator was added to the same well. The solution in the well turned blue. This solution was titrated with 0.1 M HCI. The solution turned yellow...

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...
