THEORIES OF ACIDS AND BASESThis page describes the Arrhenius, Bronsted-Lowry, and Lewis theories of acids and bases, and explains the relationships between them. It also explains the concept of a conjugate pair - an acid and its conjugate base, or a base and its conjugate acid. | | | The Arrhenius Theory of acids and basesThe theory * Acids are substances which produce hydrogen ions in solution. * Bases are substances which produce hydroxide ions in solution.Neutralisation happens because

Acid-Base Imbalance Janet J Memoli Grand Canyon University NUR 641E September 30, 2015 Acid- Base Imbalance One of the basic concepts that new nurses need to learn is that homeostasis in the body is maintained by the acid base balance in the body. That concept is critical when looking at arterial blood gases. This can help guide the nurse to anticipate what the doctor will order and the education that she needs to give the patient and the family. This case study should help to illustrate

ACID-BASE DISORDERS MADE SO EASY EVEN A CAVEMAN CAN DO IT Lorraine R Franzi, MS/HSM, RD, LDN, CNSD Nutrition Support Specialist University of Pittsburgh Medical Center Pittsburgh, PA I. LEARNING OBJECTIVES The clinician after participating in the roundtable will be able to: 1) Indicate whether the pH level indicates acidosis or alkalosis. 2) State whether the cause of the pH imbalance is respiratory or metabolic. 3) Identify if there is any compensation for the acid-base imbalance. II

HCO3– = 18 mEq/L. Questions 1. What is the relationship between acid-base balance and serum potassium level? 2. What is the reason for L.S.’s low urine output? How should her fluids be managed? 3. Categorize and explain the probable cause of L.S.’s acid-base disorder. 4. Can L.S. compensate for her acid-base disorder? Why or why not? 5. How should her acid-base imbalance be medically managed? 1. Acid-base balance can influence the serum K+ levels detected in the blood. When

Nurs 2820 Fluid, Electrolyte, and Acid-Base Balance Name: _______________________________________ Case Study Jimmy Lewis is brought to the hospital emergency room by some friends. He had been vomiting for several days and was complaining of heart palpitations. Mr. Lewis is a 58-year-old white male who is homeless. He has not had any health care for at least 10 years. He is an alcoholic and drinks a quart of gin or vodka every day. He does not have a job, and his family is all out of state

Abstract Buffer solutions were prepared and their pH measured to determine their buffering capacity. Three buffer solutions were utilized; an undiluted buffer, a diluted buffer solution with 10ml water and a diluted buffer solution with 18ml water. In the undiluted buffer solution there was minimal pH change with a high of 6.78 and a low of 6.47. In the buffer solution in which 10ml of water was added there was minimal pH change with a high of 6.78 and a low of 6.23. In the buffer solution in which

BUFFER SOLUTION Buffer solution is a solution which resist any change in its pH an addition of strong acid or alkali. Types 1 Mixture of weak acids with their salt with strong base i.e. (weak acid + salt of weak acid , conjugated base) 2 Mixture of weak bases with their salt with strong acid i.e. (weak base + salt of weak acid , conjugated acid) Examples: H2CO3/NaHCO3(Bicarbonate buffer) (Carbonic acid and Sodium Carbonate) CH3COOH/CH3COONa(Acetate buffer) (Acitic acid and Sodium acetate)

Introduction Buffer is a solution that resists a change in pH when bases or acid are added. Solutions that are acidic contain high concentrations of hydrogen ions (H+) and have pH values less than seven. Buffer usually consist of a weak acid, and its conjugate base or a weak base and its conjugate acid. The function of buffer is to resist the changes in hydrogen ion concentration as a result of internal and environmental factor. This buffer experiment is important so that we relies the important

Acid-base disturbances The Acid Base Imbalance Regulation of hydrogen ion concentration in the body is a necessity for normal body functions.1 H + concentration in all body fluids are maintained to maintain pH ranges within narrow limits, this service is known as the balance acid-base (AB) 2.Arterial blood pH is maintained between 7.35-7.45, venous blood remains near 7,352. Most diseases / conditions disrupt AB, AB changes may be more harmful than the initial pathology. When AB is affected, causing
