Question
Data collected for a particular subject during the acid baseexperiment were
- time between urine collections = 30 min
- urine volume collected = 73 mL
- pH of urine = 7.12
- Buffer-bound H+ concentration = 4.5 µmol/mL
Calculate the:
- urinary minute volume (urine flow rate)
- excretion rate of free H+ ions
- excretion rate of total H+ (free and bound)Â Â
Then compare the excretionrate of free H+ ions and that for buffer-boundH+ and explain why the H+ excretion ratecalculated from urine pH underestimates total H+excretion.
Please provide a clear and detailedanswer to help me understand. Thank you!
