Question
Chapter 14, Problem 14.81FU
Interpretation Introduction

Interpretation: The pH of the stomach fluid should be determined.

Concept Introduction:

  • pH stands for "potential of hydrogen", it is a measure of alkalinity or acidity of water-soluble substances. pH number ranges from 0 to 14.
  • pH is a logarithmic scale which specify the acidity or basicity of the solution.
  •   pH=log[H+]

      pOH = -log [OH]-

      pH + pOH = 14

  • Neutral solution- A solution is neutral if pH=7
  • Acidic solution- A solution is acidic if pH<7
  • Basic solution- A solution is basic if pH>7

Expert Solution & Answer
Check Mark

Answer to Problem 14.81FU

The pH of the stomach fluid is 3.7.

Explanation of Solution

Given:

[H3O+] = 2.0 × 10-4 M

pH is a logarithmic scale which specify the acidity or basicity of the solution. The mathematical formula to determine pH is:

  pH=log[H3O+]

Substituting the values:

  pH = -log(2×10-4M)pH=-log2-log10-4pH=0.30+4pH= 3.7

Conclusion

The pH of the stomach fluid is 3.7.
