Describe the blood hydrogen carbonate buffer system. What happens when blood acidity rises? Show the equation.
What happens when the blood becomes more alkaline? Show the equation.
Distinguish between strong and weak acid. List some clinical uses of these acids and write equations for their dissociation in water.
The human body needs a blood pH between 7.35-7.45 and uses the behavior of H2CO3 to resist any pH changes caused by outside influence such as O2 intake or CO2 removal.
As shown in the image below whether an acid is added or a base is added the system will respond by forming the opposite molecule. Since overall the amount of base and acid has not changes the pH will not change either.
There is a limit to how much the buffer can prevent the pH change however.
This is for a buffer solution of sodium acetate.
