ACID / BASE BUFFER SYSTEMS
A buffer solution is a solution that contains both an acid and a salt containing the conjugate base / acid in sufficient concentrations so as to maintain a relatively constant pH when either acid or base is added. In this experiment a selection of buffer solu...
Purpose: To find out if the Unknown substances are bases or acids.

Equilibrium and Acid Base Test Review: May 2012
Things to know:
1. Explain DYNAMIC EQUILIBRIUM. Why does a reaction at equilibrium look like it is NOT reacting?
2. Are all reactions equilibrium reactions? What assumptions do we make when we say that a reaction does NOT take place...
ACID DISSOCIATION CONSTANT OF AN INDICATOR DYE
Using spectrophotometric method:
determine the wavelengths at which the acid and base forms of the dye in aqueous medium exhibit maximum absorption;
determine the molar absorptivities of the acid and base forms of the dy...
The Determination of Acid Constant Ka
When an acid or base dissolves in water, a certain percentage of the acid or base particles will
break up, or dissociate, into oppositely charged ions. The Arrhenius theory defines an acid as a compound that can dissociate in water to yield hydrog...
EXERCISE 10: Acid-Base Balance
ACTIVITY 1: Hyperventilation | Answers |
1. A substance that dissolves in water to release hydrogen (H+) ions is called a(n) _______. | Acid |
2. Which of the following is not a regulatory mechanism for acid/base balance in the body? a. the kidneys...
Extraction is a purification technique used in organic chemistry to separate compounds from a mixture of two or more compounds. There are three different extraction techniques: liquid-liquid extraction, solid-liquid extraction and chemically active extraction. All three types of extra...

ACTIVITY 1 Hyperventilation
The normal pressure range for carbon dioxide in the blood is 35-45mmHg. The normal ph range for blood are between 7.35 and 7.45
2. Describe what happened to the pH and the carbon dioxide levels with...
Separation of Organic Compounds by Acid-Base Extraction Techniques
A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this exp...
Lab 7: The Kidney’s Role in Fluid Balance
The renal system performs a vital role in homeostasis. The kidneys’ ability to retain valuable constituents and expel metabolic wastes from the body enables this system to regulate the volume, osmolarity, and pH of body’s internal flu...
Acid base balance
Normal arterial blood pH is 7.36 to 7.44 remains within a range.
Many cellular functions depend on pH alteration of pH causes deterioration of enzymatic actions
Eg :- Loss of myocardial contractility – heart failure
Loss of vascular tone – fall of blood pressure
