Based on this information, which statement best summarizes the blood condition that might result when an individual has a respiratory condition that causes the blood to contain too much CO2?

The pH of a liquid is a measure of its acidity or its alkalinity. Even small changes in pH of human blood can cause very serious health problems.

Carbon dioxide (CO2), is one of the dissolved gases present in healthy blood. CO2 normally mixes with the water in blood to form a mild acid, carbonic acid, which lowers the blood pH.If a health problem causes the dissolved carbon dioxide to increase or decrease, the blood’s pH would change and could produce an unhealthy pH level.

Based on this information, which statement best summarizes the blood condition that might result when an individual has a respiratory condition that causes the blood to contain too much CO2?
A . The blood pH will remain the same.
B . The blood pH will be lowered.
C . The blood will be less acidic.
D . The blood’s white cell count will be greatly decreased.
