The higher the concentration acid and conjugatebase in a buffer, the smaller the pH change when acid or base isadded. Determine whether the above statement is true or false byperforming the following calculations:

1. compute the pH change in the following twobuffers when 1 g of KOH is added:
ka = 5.71 x 10^-10
a. 500ml of a 0.10m nh4cl and 0.10m nh3buffer
b. and when it is added to 500ml of a 1.00m NH4Cland 1.00m NH3 buffer...

In which buffer does the largest pH changeoccur??? Does concentration of the buffer solution effect it'sbuffering capacity??

1. Calculate the pH of a buffer solution made by adding 5.0g ofanhydrous sodium acetate (NaC2H3O2) to 50mL of 0.100 M acedticacid. Assume there is no change in volume on adding the salt to theacid. pKa for acetic acid is 4.7.

Buffer capacity refers to the amount of acid or base a buffer canabsorb without a significant pH change. A 0.5M buffer can absorb 5xas much acid or base as a 0.1M buffer for a given pH chnage.

You are given 60mL of 0.50M phosphate buffer, pH= 6.83. Thestarting composition of the buffer, both in terms of concentrationand molar quantity of two major phosphate species is:
Concentration of HPO4^2-= 0.304M
Concentration of H2PO4-= 0.196M
Molar quantity of HPO4^2-= 18.2 mmol
Molar quantity of H2PO4-= 11.8 mmol

a) You add 1.7 mL of 1.00 M HCL to the buffer. Calculate the molarquantity of H30+ added as HCL and the final molar quantity ofHPO4^2- and H2PO4- at equilibrium?

b) What is the new HPO4^2-/H2PO4- ratio and new pH of solution? ThepKa of H2PO4- is 6.64. Use henderson-hasselbach.

C) Now take a fresh 60mL of the 0.50M pH of 6.83 buffer and add3.7mL of 1.00M NaOH. Caclulate the new pH of the solution.

Using the equations (discussed above) showing the relationship between [acid], [conjugate base] and [buffer concentration], mathematically show the negligible change in pH even when 2ÂµL of 10M HCl is added to 100 ml of 50 mM Phosphate buffer at pH 6.9. To address this problem, the following steps will be needed: (i) You will have to calculate the pH of the buffer after adding the 2ÂµL of 10M HCl (ii) To do this, calculate the new concentration of [acid] and [conjugate base] after the addition of 2ÂµL of 10M HCl, and (iii) to appreciate the effect of buffers, show the pH change in 100 ml of water after upon adding 2ÂµL of 10M HCl that does not contain the phosphate buffer ions.
