2. -12 points GVSUBiochem1 1.4.P.002 My Notes The hydronium ion concentration, [H3 or more simply the hydrogen ion concentration, [H+]), for venous blood is 4.17 x 10-8 NM a. What is the pH of this fluid? b. Is this pH within the normal range? (Use table at right) Approximate Normal pH Ranges for a Variety of Body Fluids Body Fluid Bile Arterial Blood Venous Blood Cerebrospinal Fluid Urine Lower limit 7.5 7.34 7.31 7.30 4.5 Upper limit 8.8 7.44 7.41 7.36 8.0 The pH is within the normal range The pH is outside the normal rangeExplanation / Answer
a.
pH = -log[H3O+]
pH of venous blood = -log(4.17 X 10-8)
= 7.38
pH of venous blood = 7.38
b.
According to given table range of pH of venous blood = 7.31 to 7.41 and our calculated pH = 7.38 therefore pH is with in normal range.
The pH within the normal range
