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.

Buffer # Initial moles of Tris-HCL Initial moles of Tris Post Addition of HCL
mmol of Tris-HCl Post Addition of HCL
mmol of Tris Predicted pH Buffer 1 8.75e-05 0.0001625


Buffer 2 0.0001125 0.0001375


Buffer 3 0.0001 0.00015


Explanation / Answer

Need to know the molarities of the buffers from 'Part1'.
