Question
Complete the following table using the molarities you calculated for each buffer in Part 1. Using a 10 mL aliquot of the buffer, show the change in mmoles when 0.01 mL of 2.0M HCl is added to the buffer. Predict the change in pH after the addition.
Complete the following table using the molarities you calculated for each buffer in Part 1. Using a 10 mL aliquot of the buffer, show the change in mmoles when 0.01 mL of 2.0M NaOH is added to the buffer. Predict the change in pH after the addition.
