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)  

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!
