Suppose you wanted to make a buffer of exactly pH 7.00 using KH2PO4 and Na2HPO4. If the final solution was 0.18 M in KH2PO4, you would need 0.25 M Na2HPO4. Now assume you wish to make a buffer at the same pH, using the same substances, but want the total phosphate molarity ([HPO42−]+[H2PO−4]) to equal 0.20 M. What concentration of the Na2HPO4 would be required?

Their hypothesis was that phosphocholine joined with some cellular component to yield lecithin. In an earlier experiment, incubating 32 P-labeled phosphocholine at physiological temperature (37 °C) with broken cells from rat liver yielded labeled lecithin. This became their assay for the enzymes involved in lecithin synthesis. Determine the optimal pH for this enzyme and characterize the enzyme activity at different pH values. -O-P-O-CH2-CH₁₂-N(CH3)3 Phosphocholine H₂C-O-C-R HC-O-C-R2 + + + Cell fraction + ?
