Q4. Part 1 Predict which side of the equilibria, for the following two reactions, lies towards the left or towards the right and briefly explain why. (Note: You will need to find the pKa values in water of the acid and the conjugate acid to begin to solve the problem). Part 2 Also, show the movement of electrons using curly arrows between the two reactants of each of the reactions. H;NEt Reaction 1 H,NEt Ethylamine H3C H3C : OH :0: Reaction 2 H CH3 ICH3 CH3 H3C H3C CH3 Acetone

A solution has 5.25 mmol L-1 total phosphate (pKa = 2.1, 6.8, 12.4). If the pH of the solution is 7.4 at equilibrium, calculate the concentration of H2PO4- (in mmol L-1).
Need this answered pretty quick do not need it super detailed just want to make sure i did it correct this is non graded. Please do not accept this problem if it will take you more than 20 minutes to solve
4. Which molecule has the lowest pKa for the H proton at the very bottom (the H that's in the same spot for all the molecules)? Please explain your reasoning.
Figure 2: Re-arranging the expressions below, make a separate plot showing the concentration of the protontated form and the de-protonated form (both on the y-axis) for a total acid concentration of 0.01M for the same pH values you used above (x-axis). αHA [HA] [A] TOT [A-] αA- = [A] TOT
8.) You are working in lab and you see your manager plans to set up the three following acid base reactions as drawn. Given your experience in predicting acid base reaction outcomes, tell him which reactions will work by writing YES (if the reaction will go as written) or NO (if the reaction is doomed and will not go as written, meaning the starting materials are favored) below the reaction arrow (under the question marks).
