Experiment 3 : Preparation of Solutions and Buffers Objectives : 1. To study and understand the principle theory and formula of preparation of buffer and solution. 2. To learn the methods of buffer and solution preparation. 3. To focus on concentration units of molarity‚ percentage of concentration‚ and dilution of solution. Introduction : When a substance‚ called a solute‚ is dissolved in another substance‚ called the solvent‚ a solution is formed. A solution is known as a homogeneous

BUFFERS By: Luis P. Bazan‚ RPh.‚ Ph.D. A buffer solution is a solution of: 1. A weak acid or a weak base and 2. The salt of the weak acid or weak base Both must be present! A buffer solution has the ability to resist changes in pH upon the addition of small amounts of either acid or base. Consider an equal molar mixture of CH3COOH and CH3COONa CH3COOH (aq) H+ (aq) + CH3COO- (aq) Adding more acid creates a shift left IF enough acetate ions are present 16.3 Which of the

Peaceful resistance to laws positively impacts a free society because it informs and educates the government on how Americans react to certain laws. This can be observed in many of the current events that are going on in America today and have gone on the past the past. One prime example of this is during the 1960’s Civil Rights Movement. Charismatic leaders such as Martin Luther King Jr. peacefully influenced American politics and ultimately brought about the Civil Rights Act of 1964 which disallowed

Antibiotic resistance results from bacteria changing in ways that make those antibiotics no longer useful. Resistance is a common yet problematic issue in treating pulmonary exacerbations or infections in people with Cystic Fibrosis (CF). Not all bacteria are bad. However‚ there are some that can cause infections. As bacteria are exposed to antibiotics over time‚ resistance may develop‚ and the number of antibiotics we have to kill the bacteria decreases as well. Thus‚ it is important to learn
