Detailed explanation-1: -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-2: -What is its pH? Human blood has a pH between 7.35 and 7.45. Which of the following best describes human blood? strong acid.
Detailed explanation-3: -Blood is an alkaline buffer of weak acid and weak base. Thus, blood pH is slightly basic due to presence of bicarbonate (weak base) in it. The blood pH in our bodies lies between 7.35 to 7.45, which means blood is slightly alkaline in nature.
Detailed explanation-4: -The pH of human blood is between 7.35-7.45. The pH scale, or the acid-base scale, runs from 0 to 14.
Detailed explanation-5: -So, the correct answer is ‘7.4’.
