Concentration And Reaction Rate
1,776 wordster> How concentration affects reaction rate. The aim of this investigation is to see how the concentration of a reactant in ratio to the reactor affects the rate of a reaction. When hydrochloric acid and Thiosulphate react together sulphur is liberated this means that as the reaction goes on the solution will become yellow and will change from being transparent to translucent to opaque. The sulphur is formed as a solid but not in the usual precipitation way. Na 2 + S 2 + 2 HCL 2 NaCl+...

Chemistry Lab Concentration Effects On Rate Of Reaction
1,070 wordsAim: The aim of this investigation is to investigate the rate of reaction of magnesium (mg) with Hydrochloric acid (HCl). After studying the availability of equipment I have chosen to investigate how concentration can affect the rate of reaction. Other variables that affect this investigation are: - Concentration of solution - Temperature - Surface area of a solid - Catalyst - Light - Pressure of a gas Prediction: I predict that when changing the concentration of hydrochloric acid and water, the...

Carbon Atoms Measuring Cylinder
3,479 wordsComparing Energy Release from the Combustion of Alcohols I am going to investigate the energy released by burning alcohol called the enthalpy of combustion. I will be trying to find out how the number of Carbon atoms the alcohol contains effects the enthalpy change that occurs during combustion. The Alcohols are a series of related organic molecules where each member has the -OH (hydroxyl) group in the molecule. The general formula of an alcohol is: Cn H 2 n+ 1 OH, where n is the number of Carbo...

Carbon Dioxide Measuring Cylinder
3,019 wordsAim 1 To find Fermentation Aims Aim 1 To find out what factors affect how quickly bread dough rises. There are a number of factors that affect how quickly bread dough rises. These are: · Amount of sugar-if the amount of sugar is increased, the rate of reaction will increase. Adding a higher concentration of sugar will increase the sugar particles in a given space. As the mixture is heated, the sugar particles will begin to move. Due to a lack of space, this would result in collisions. Thu...

Bunsen Burner Hydrochloric Acid
762 wordsThe Problem: I am going to find out how temperature can affect the rate of reaction. Background information: Factors that change the rates of reactions are: ? Temperature? an increase in temperature will make the reaction occur faster. This happens because the particles of that substance move faster when it is heated. Because the particles move faster, they would collide more, making the reaction rate faster. ? Concentration? the increase in concentration, the greater and faster the reaction. Th...

Sodium Chloride Permeable Membrane
2,568 wordsScenario Plants in the soil have their roots in a dilute solution of mineral ions. When they are suddenly flooded with seawater, concentration of which is 0. 3 molar Sodium Chloride, they are observed to wilt and become flaccid. Aim The aim of this experiment is to investigate the movement of water into and out of plant cells by osmosis. The cells chosen for study will be taken from potato tubers as they provide a ready supply of uniform material. Background Information Any substance dissolved i...

Cm Measuring Cylinder
4,557 wordsPhysics CAT One Extended Untitled Physics CAT One Extended Practical Investigation Report Student Number: Purpose The Purpose of this investigation is to explore how the terminal velocity of a sphere falling through glycerol varies with the temperature of the glycerol and the size of the sphere. Introduction In the early stages of the project it was intended to investigate how the speed of a sphere falling through glycerol varies with the size of the sphere. However, after analysis it was decide...

Baking Soda Hydrochloric Acid
3,324 wordsAim: To find which powder, of four, is best for neutralising excess stomach acid. Prediction: With stomach pain relief powders being a consumer product, I predict that the best cure for neutralising a build up of stomach acid will be the one which has the lowest cost to successfully neutralise the dilute hydrochloric acid (HCl) (0. 5 mol) (to represent the excess acid found in our stomachs). This powder would have be the one which costs less than any of the others to bring the acid build up to a...
