- Calculate the average concentration of Vitamin C in each sampleFor the CO2 impact experiment station: 1) Obtain two plastic cups, red cabbage indicator, a straw, and plastic wrap. 2) Fill each cup approximately one-quarter to one-third full of tap water and add ~10 mL of the red cabbage indicator. 3) Place the two cups side by side on a sheet of white paper. 4) Place the straw into one of the beakers and cover that beaker with the plastic wrap. 5) Carefully blow bubbles into the test cup for 3 min. and observe both cups. 6) Compare the color to the control cup and record any differences. This the Question: Did the beaker with the solution into which CO2 was bubbled change pH/color? By how much? Is this what, you would predict, based on your knowledge of the chemistry of CO2?Pls help ASAP. Pls show all work and calculations.
- Thank you! Data included in picture! No hand drawn graphs!! Determine the equivalence point of sudsy ammonia/citric acid reaction by graphing the titration data (pH vs volume citric acid) from Table 1: No Indicator Data Table. Draw a green arrow (use ‘Insert Shape’ feature to do this once you have copied your graph from Excel) on your graph indicating the data point that represents your equivalence point. Use a graphing software to create the x-y scatter plot showing the pH of the experimental solution as a function of the volume of citric acid (the titrant) added for the titration in Part 4. On your graph, the x-axis should be the volume of citric acid added (mL), and the y-axis should be the pH of the experimental solution at that volume. Do NOT connect your points; no trend line needed and make sure to: · Label the axes including the units in parentheses. · Include a figure legend (text below the graph) explaining the data in your graph that includes the arrow…1)What is the value of the Langmuir constant "a"? 2)What is the value of the Langmuir constant "b"?Please send me the question in 20 minutes it's very urgent plz
