Chem Final Write Up- Kool Aid Lab
Total Acid
This part of the lab requires titration of Kool Aid with an NaOH solution. The reason titrations are used is to determine the concentration of an unknown solution by reacting a strong acid with a strong base. Titrations are hard to accomplish, though, due to the fact that indicators used to show the endpoints are very sensitive and one drop could make the solution titrate past its endpoint.
Blue stock solution: 3 mg/L
Yellow stock solution: 35 mg/L
Phenolphthalein is the indicator used (6 drops per titration)
Molarity of NaOH used: .05056 M
Dillution factor: 100mL/25mL green Kool Aid= 4
Titration 1: Start= 0.00 mL End= 14.75 mL  14.75 mL
Error
((14.80 mL-14.55 mL)/(14.7 mL)) x100 = 1.701%
Hydrogen Ion: (Molarity NaOH) x (Volume NaOH) = mol NaOH [1:1 ratio between NaOH & H+]= mol H+
Titration 1: (.05056 mol/L) x (.01475 L)= .00074576 mol NaOH = .00074576 mol H+
Titration 2: (.05056 mol/L) x (.01455 L)= .00073565 mol NaOH = .00073565 mol H+
Titration 3: (.05056 mol/L) x (.01480 L)= .00074829 mol NaOH = .00074829 mol H+
Hydrogen Ion Per Liter: (Mols/L of H+  25 mL = .025 L x 40 = 1L)
Titration 1: (.00074576 mol H+/ .025 L) x 40 = .0298304 mol H+/L
Titration 2: (.00073565 mol H+/ .025 L) x 40 = .029426 mol

The aim of this lab was to determine the volume of one mole of hydrogen gas at STP (standard temperature and pressure). In the experiment, a magnesium ribbon was placed at the bottom of an eudiometer tube and allowed to react with 2M hydrochloric acid. The volume of hydrochloric displacement was measured and calculations determined the molar volume of hydrogen gas produced inside the eudiometer tube. After performing and taking the average data of two trials, it was concluded that the calculated value of one mole of hydrogen gas at STP was about 22.35 L/mol. Rounding up, it can be concluded that one mole equals 22.4 L/mol, which is the accepted value of the volume one mole of an ideal gas takes up. However, there was a…

After doing this lab it was found that the concentrations of the vinegar were close to the claimed value by the manufacturers. The great value brand had the exact concentration that was claimed. The concentration was 0.87 mol/L. The no name brand had a lower concentration of vinegar. Its concentration was 0.85mol/L. This was because the bottle had been left open for a long time, and it’s ions were lost in the air. This has been further discussed in our sources of error. The final Brand was Heinz. The concentration for this brand was very close. Its concentration was 0.86mol/L. Overall we can say that Great value had the claimed concentration and other were also very…
