Explanation:
Detailed explanation-1: -Acidosis is caused by an overproduction of acid that builds up in the blood or an excessive loss of bicarbonate from the blood (metabolic acidosis) or by a buildup of carbon dioxide in the blood that results from poor lung function or depressed breathing (respiratory acidosis).
Detailed explanation-2: -The increased CO2 is what leads to an increase in hydrogen ions and a slight increase in bicarbonate, as seen by a right shift in the following equilibrium reaction of carbon dioxide: CO2 + H2O-> H2CO3–> HCO3-+ H+
