Assigned Acid: Pyruvic Acid – Electrostatic Potential is 331.4 kJ/mol Ka = 4.1 x 10^-3 I believe the pKa is 2.4? Data for graphing pKa with Assigned Acid 1. Calculate the pka for your assigned acid using the given Ka. Show all your work for credit. 2. Graph the maximum electrostatic potential given for each molecule vs strength of the acid as represented by its pKa value using XY scatter plot (Table 1). Make sure to label your acid. Electrostatic...
please show all work thank you im advance Experiment #5-Acidity and Electrostatic Potential Experiment #5: Correlation of Acidity with Electrostatic Potential This Experiment is Done in Groups of 2 Background: his laboratory experiment is focused on theoretically predicting the acidity of several molecules. A software package called "Spartan" was used to predict the structure electrostatic potential of each molecule. The electrostatic potential at a point P is defined as the Coulomb energy of interaction between the electron-charge cloud of the...
5. In 3 to 4 sentences, define electrostatic potential and acid strength and explain why there exists a correlation between the two? Does your assigned acid follow this trend or does it appear to be an outliers? Explain. H4 Pyruvic Acid - Electrostatic Potential is 331.4 kJ/mol Ka 4.1 x 10-3 the Electrostatic Potential Map word document posted on y the region(s) with the most positive electrostatic potentia ed acid and explain why that region is the most positive. Y...
In 3-4 sentences, explain why there exists a correlation between electrostatic potential and acid strength? Does your assigned acid follow this trend or does it appear to be an outlier? Explain. Our assigned acid is Benzoic Acid. The pKa is 4.2 (Ka was 6.5 x10^-5) and electrostatic potential was 279.3. Heres what the graph looked like PLEASE HELP

Answer the following parts Part A. Once you have obtained the electrostatic potential value for your unknown acid, use the plot you obtained for the known carboxylic acids to obtain the pK, value for your unknown acid. Do not "eyeball" the pK, value on the graph. Rather, using your trendline to calculate the value will be a more accurate determination. Show your calculation in the space below Part B. (4) Using a reputable source, report the pKa literature value for...
