Concentration of a Solution: Beer’s Law The objective of this experiment is to determine the concentration of an unknown copper sulfate solution. You will be using the Colorimeter. In this device‚ red light from the LED light source will pass through the solution and strike a photocell. A higher concentration of the coloured solution absorbs more light (and transmits less) than a solution of lower concentration. The Colorimeter monitors the light received by the photocell as either an absorbance

Americans depend on this energy in almost every way imaginable; from cooking to cleaning‚ from working to traveling‚ to heating and cooling. Wind is a byproduct of solar energy; the uneven heating of the air over land and water creates wind as warm air rises and cool air rushes in to take its place (Bezdek‚ 29 Oct. 2013). Although some people tend to dislike the idea

TUTORIAL1 WITH INFORMATION TO SOLUTIONS 1. For most products‚ higher prices result in a decreased demand‚ whereas lower prices result in an increased demand. Let d = annual demand for a product in units p = price per unit Assume that firm accepts the following price-demand relationship as being realistic: d = 800 – 10p where p must be between $ 20 and $70. a. How many units can the firm sell at the $ 20 per-unit price? At the $ 70 per-unit price?

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
