One function of our blood is to carry CO2CO2 from our tissues to our lungs. It is critical that the pH of our blood remains within the normal pH range. Our blood is buffered to maintain that normal pH range and the primary buffer system is composed of HCO−3/H2CO3HCO3−/H2CO3. Assuming that the concentrations of HCO−3HCO3− is 0.014M and H2CO3H2CO3 is 0.0012M, what is the pH value of the blood? Ka =4.2x10-7 for H2CO3

Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.
