Acid-Base Balance in Biological Systems starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Acid-Base Balance in Biological Systems.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

A buffer solution contains 0.3 M HA and 0.3 M A⁻. If the pKa is 7.0, what is the pH of the solution?
A patient has a blood pH of 7.50. Is this condition called acidosis or alkalosis?
A patient with uncontrolled diabetes develops rapid, deep breathing (Kussmaul respiration). Explain the physiological reason for this response.
Calculate the pH of a buffer solution where the concentration of the acid (HA) is 0.1 M, the concentration of its conjugate base (A⁻) is 0.2 M, and the pKa is 6.0.
Describe the difference between respiratory and metabolic acid-base disorders.
Describe the relationship between pH and hydrogen ion concentration.
Describe the role of hemoglobin in acid-base balance.
Explain how hyperventilation can affect blood pH.
Explain how the kidneys compensate for respiratory acidosis.
Explain why maintaining acid-base balance is important for enzyme function.
Explain why severe diarrhea can lead to metabolic acidosis.
Name two physiological buffer systems other than the bicarbonate buffer system.
What is the effect of adding a strong acid to a buffered solution?
What is the effect of hypoventilation on blood pH?
What is the main effect of respiratory acidosis on blood pH?
