ACID BASE IMBALENCE INTRODUCTION The body normally maintains a steady balance between acids‚ produced during metabolism and bases that neutralize and promote the excretion of the acids.Many health problems may lead to acid base imbalance.Patients with Diabetis mellitus ‚COPD‚and kidney disease frequently frequently develop acid base imbalences. Vomiting and diarrhea may also cause acid base imbalance.The kidneys are an essential buffer system for

oblongata as well as airway obstruction may cause respiratory acidosis. 3. Explain how the renal system would compensate for respiratory acidosis. The kidneys regulate the amount of H+ ions and HCO 3- excreted in the urine which regulate acid base balance. A C T I V I T Y 3 Renal Responses to Respiratory Acidosis and Respiratory Alkalosis 1. Describe what happened to the concentration of ions in the urine when the PCO2 was lowered. How well did the results compare with your prediction?

Task 4 – The Maintenance of the Acid – Base balance in the body (D1) pH is measured based on its acidity and alkalinity. There are many substances around the body that have different pH values. A pH of 7 is usually considered neutral‚ neither acid nor alkaline‚ this is the pH of water. In the body the acids and bases need to be in very close balance‚ this is called ‘acid base homeostasis. If it goes off too far in either direction then it could be fatal to the body. For example in the body the blood

LAB 6. ACIDS AND BASES: PH AND BUFFERS PURPOSE: To determine the pH of common acids and bases using a pH meter‚ pH paper‚ and red cabbage indicator. To test the effect of adding an acid or base to a buffer solution. SAFETY CONCERNS: Always wear safety goggles. Wash with soap and water if skin contacts acids or bases. ACIDS: An Acid is a substance that when dissolved in water will produce hydrogen ions‚ H+‚ in the solution. An acid that does not contain carbon is called an inorganic

Suggested time allotment: 5 to 6 hours MODULE 2 ACIDS AND BASES In Module 1‚ you identified common properties of solutions using different methods. You learned how to report the amount of the components in a given volume of solution. You also found out that not all solutions are liquid. Some of them are solids and others are gases. Towards the end of the module‚ you investigated the factors that affect how fast a solid dissolves in water. Most of the solutions you studied in Module 1
