Detailed explanation-1: -Answer and Explanation: The normal pH range of blood is 7.34-7.45, which is slightly alkaline.
Detailed explanation-2: -Blood is normally slightly basic, with a normal pH range of about 7.35 to 7.45. Usually the body maintains the pH of blood close to 7.40. A doctor evaluates a person’s acid-base balance by measuring the pH and levels of carbon dioxide (an acid) and bicarbonate (a base) in the blood.
Detailed explanation-3: -Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.
Detailed explanation-4: -pH above 7 is alkaline and below 7 acidic. Thus the pH of blood (7.35-7.45) is slightly alkaline although in clinical medicine the term alkalosis is, perhaps confusingly, reserved for blood pH greater than 7.45 and the term acidosis is reserved for blood pH less than 7.35.
Detailed explanation-5: -As this diagram shows, pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
