Carbon dioxide-and your body pH

Carbon dioxide-and your body pH

• Normal body pH is about 7.35 - 7.45.

• In your body when you are low on CO2 you can get the hic ups . The lack of CO2 affects the diaphragm and forces air out the glottis and epiglottis.

• pH too high

• Normal body pH is about 7.35 - 7.45.

• Hyperventilation can occur when rapid and deep breathing causes a deficiency of CO2 in the blood. The pH level is too high.

• Yawning is a mechanism that your body uses to get rid of extra CO2.

• Note: if pH goes above 7.8 or below 6.8 death can occur.

• The hydrogens from a strong acid plus ammonia will form an ammonium ion formed salt.

• These salts are usually aqueous and no water is produced.
