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

The Power of Concentration By Remez Sasson When I was a child‚ I saw how a magnifying glass could burn a piece of paper‚ when the rays of the sun were focused through it. The fire could start only when the sun’s rays were concentrated to a small point. When the magnifying glass was moved too far away or too close to the paper‚ the rays were not focused enough and nothing happened. This experience describes vividly the power of concentration. This power can be described as focused attention. It

THE EFFECT OF CONCENTRATION ON REACTION RATE INTRODUCTION • Concentration is one factor which has an effect o the rate of a chemical reaction. In chemistry we describe concentration in terms of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium

managed to escape from Germany’s wrath. Others went hiding in Germany‚ hoping that the Allies would invade Germany in time before the Nazis find them. During all this‚ concentration camps were being made. A concentration camp is a place where large numbers of people‚ especially political prisoners or persecuted members of a minority‚ are imprisoned in a small area with inadequate facilities‚ sometimes to provide forced labor or to await mass execution. Many of these concentration camps later became

CHAPTER 1 INTRODUCTION A. Background of the Study Concentration has been defined as the ability to direct one’s thinking in whatever direction one would intend. Concentration plays vital roles in doing well in studies. A student has to work really hard and concentrate firmly to get concepts well in mind. All students have the ability to concentrate some of the time. But at other times students’ thoughts are scattered‚ and their minds race from one thing to another. They don’t have the ability to
