Question

Part 1:

What is the concentration of your NaOH(aq) solution?

1.00×10^-1 M NaOH

Ok.

Part 2:

You will then make a Kool-Aid solution by dissolving the powder in an entire packet of lemon-lime Kool-Aid in 250.00 mL solution.  You find the powder in a packet of lemon-lime Kool-Aid has a mass of 3.654 g.

In Part 2 of the lab you titrate 5.00 mL of the lemon-lime Kool-Aid (with 5 drops of thymol blue indicator) with your NaOH(aq) solution. The titration requires 10.62 mL of NaOH(aq).

Determine the number of moles of NaOH(aq) required to titrate 5.00 mL of your Kool-Aid solution.

1.05×10^-3 mol NaOH

Ok.

Part 3:

Determine the number of moles of NaOH(aq) that would be required to titrate 250.00 mL of your Kool-Aid solution (the entire packet).

5.25×10^-2 mol total acid

Ok.

Part 4:

In Part 3 of the lab you titrate 25.00 mL of the lemon-lime Kool-Aid (with KI, HCl, and starch) with 0.001000 M KIO₃(aq) solution. The titration requires 10.33 mL of KIO₃(aq).

Determine the number of moles of ascorbic acid in 25.00 mL of your Kool-Aid solution.

3.099×10^-5 mol ascorbic acid

Ok.

Part 5:

Determine the number of moles of ascorbic acid in 250.00 mL of your Kool-Aid solution (the entire packet).

3.099×10^-4 mol ascorbic acid

Ok.

Part 6:

If you titrated the entire packet of Kool-Aid, how many moles of NaOH(aq) would be neutralized in the titration due to the ascorbic acid?

mol NaOH

Please enter your results to the correct precision.

Part 7:

To titrate the entire packet of Kool-Aid, how many moles of NaOH(aq) would be neutralized in the titration due to the citric acid?

mol NaOH

Part 8:

Determine the number of moles of citric acid in the packet of Kool-Aid solution.

mol citric acid

Answer 1

Part 6:

The number of moles of ascorbic acid in 250.00 mL of your Kool-Aid solution (the entire packet).

mol .

If you titrated the entire packet of Kool-Aid, moles of NaOH(aq) would be neutralized in the titration due to the ascorbic acid.

Note: 1 mole of ascorbic acid will neutralsie 1 mole of NaOH.

Part 7:

Total number of moles of NaOH required to titrate 250.00 mL of your Kool-Aid solution (the entire packet).

If you titrated the entire packet of Kool-Aid, moles of NaOH(aq) would be neutralized in the titration due to the ascorbic acid.

The number of moles of NaOH required to titrate citirc acid present 250.00 mL of your Kool-Aid solution (the entire packet).

mol .

Part 8:

The number of moles of citric acid in the packet of Kool-Aid solution

Note: 1 mole of citric acid will neutralsie 3 moles of NaOH.
