Titration is a laboratory technique used to determine the concentration of a substance in a solution. We use a concentration of a known solution to determine the concentration of the unknown solution.

We titrate the hydrochloric acid solution with unknown concentration, with sodium hydroxide.

The endpoint is when the solution has a light pink color. This indicates the acidity level has reached it’s endpoint and the titration reaction is completed.

Our result was that it took an average of 10.85ml +-2.8% of NaOH to completely titrate 10.00ml of HCl. The moles of NaOH were 1.09×10^-3 mol +-2.8%. Which gave us a concentration of HCl of 0.109M +-2.8%.

Me and my partner communicated well and helped each other when one did not understand something. We helped each other to make sure we have the correct equipment, solutions, material and calculations. We were not entirely sure of what to do but were always willing to help one another. The overall lab took a long time but was enjoyable. Me and my partner supported each other well and completed the lab efficiently.

Initial volume reading: 0.01mL +-0.05mL

Final volume reading: 14.70mL +- 0.05mL
