Question

Question 1 a) Find the pH of a solution prepared by dissolving 1.00 g of glycine amide hydrochloride (BH+); [Mwt = 110.54] plus 1.00 g of glycine amide (B); [Mwt = 74.08] in 0.10 L. pKa = 8.04

b) How many grams of glycine amide should be added to 1.00 g of glycine amide hydrochloride (BH+) to give 100 mL of solution with pH 8.00?

c) What would be the pH if the solution in part (a) were mixed with 5.00 mL of 0.1 M HCl?

d) What would be the pH if the solution in part (c) were mixed with 10.00 mL of 0.100 M NaOH?

e) What would be the pH if the solution in part (a) were mixed with90.46 mL of 0.1 M NaOH? (This is exactly the quantity of NaOH required to neutralize the glycine amide hydrochloride (BH+).)
