please I need help with this question; 7. Titration of Acetic Acid: using the equation [H^+] = (ka [HA])^1/2 for weak acids, calculate the theoretical starting pH of the titration based on the concentration of acetic acid notated on the bottle and the final concentration of the solution after preparing it for the reaction. calculate the percent error relative to the pH that was recorded in the lab. (the concentration of the acetic acid is 0.10M and the pH recorded...

I'm having trouble with these questions from the lab: polyprotic acids: titration of phosphoric acid and determination of the molar concentration of phosphoric acid in cola. 3.A student titrated 25.00 mL of cola and it required 18.27 mL of 0.0100 M NaOH to reach the 1st equivalence point. Calculate the molar concentration of phosphoric acid in this brand of cola. 4. If the density of the "Cola" drink is 1.00 g/mL. What is the mass percent of phosphoric acid in...

Please help!! Histidine is a polyprotic acid. 1. Draw a complete titration curve assuming 10.0 mL 0.10 M acid is titrated with 0.10 M NaOH. Calculate the pH at 0.10 mL intervals of base added until you have titrated all the acidic groups and added 2.0 mL of excess base. Plot the titration curve. Use the equations explained in the handout. 2. Plot the buffer capacity as explained in the handout. Explain which pH regions have the highest buffer capacity...
