HELP! I just need the steps to figured out these 3 problem. I have the answes but I can't seem to figure out how to do it and my notes aren't helping. thanks!
Determine the pH of a solution obtained by titrating 25.00 mL of a 0.107 M solution of a weak base using 75.25 mL of 0.100 M HCl( aq) as a titrant. (hint: this involves a dilution problem.)
answer is 1.32
65.5 mL of a 0.0670 M HCl( aq) solution were required to titrate a 25.00 mL sample of a weak base to its equivalence point. The pH at the equivalence point was 4.668. What is the pK b of the weak base? (assume pK w = 14.00) (Remember, pH at the equivalence point is based on total volume.)
answer is 5.98
Determine the pH of a solution obtained by titrating 25.00 mL of a 0.121 M solution of a weak monoprotic acid using 60.25 mL of 0.125 M NaOH( aq) as a titrant. (assume pK w = 14.00) (hint: this involves a dilution problem.)
