Describe the preparation of 3.00 L of 0.150 M glycine buffer, pH
8.1, from glycine and 1.00 M NaOH. What mass of glycine is
required? The appropriate pKapKa of glycine is 9.6. Apply
appropriate significant figures.
Describe the preparation of 40 liters of 0.02 M phosphate
buffer, pH 6.9, starting from solid Na3PO4 and 1M HCl. The answer
is 131.2 g of Na3PO4 + 1330 mL 1M HCl. Please explain in detail how
to get this answer.
a. Describe the preparation of 2 liters of 0.1 M
Glutamate buffer, pH 10.0. You have available monosodium glutamate
(MW=169), 0.5M NaOH and distilled water. Use pka of glutamate
9.67.
b. Momentarily distracted by having a piece of old
light fixture fall on your head, you add 10ml of the 0.5 HCL to the
2L of buffer. What would be the pH now

You are asked to prepare 500. mL of a 0.150 M acetate buffer at
pH 4.90 using only pure acetic acid (MW=60.05 g/mol, pKa=4.76),
3.00 M NaOH, and water. Answer the following questions regarding
the preparation of the buffer.
2. What volume of 3.00 M NaOH must you add to the acetic acid to
achieve a buffer with a pH of 4.90 at a final volume of 500 mL?
(Ignore activity coefficients.) Answer is not 14.5
calculate the ph of 1.0 l of a buffer that is .01 m of HNO2 and
.15 m NaO2. what is the ph of the same buffer and after the additon
of 1.0 l of 12m hcl (pka of HNO2 is 3.4)
