I predict that the amount
The Effect of Changing the Concentration of Sucrose on the Movement of Water into a Potato Introduction Aim 1. To use different concentrations of sucrose solution to determine the internal concentration of the potato. 2. To use different concentrations of a solution more dilute than the internal concentration of the potato to find out what the effects of different sugar concentrations have on the movement of water into the potato. Theory ====== Osmosis is the movement of
An experiment to find out how changing the concentration of acid affects the rate of reaction Planning Aim: I am to find out how changing the concentration of the hydrochloric acid (HCL) affects the rate of reaction. The hydrochloric acid will be reacting with marble chips (small, medium, large). During my experiment I will be changing one variable. This will be the concentration of the acid. I will use the concentration of HCL from 0.5 molar/dm3 to 3.0 molar/dm3. I will use 3grams
Investigating How Changing the Concentration of Sucrose Affects Its Reaction Time Aim: To find out how varying concentrations of the substrate (sucrose) affects the rate of reaction with the enzyme sucrase. Hypothesis My hypothesis is that as the sucrose concentration increases, the rate of reaction will also increase. Scientific Knowledge: [IMAGE] Enzymes are biological catalysts which increase the rate of a chemical reaction without directly taking part in the reaction. For
rate of loss of a reactant or the rate of formation of a product during a chemical reaction. We are studying the affect of changing concentration of Na2S2O3 Solution and dilute HCl. I believe these variables will affect the rate of reaction: · Surface area · Pressure · Temperature · Catalyst · Concentration Concentration ============= If the concentration of a solution is increased there are more reactant particles per unit volume. This increased the probability of reactant particles
How changing the concentration changes the rate of reaction. Introduction We are going to look at the following factors during this investigation: 1 Why altering rate could be an advantage 2 Good ideas to control the rate of reactions 3 Briefly mention the factors that can change the rate of reaction such as: - Temperature Surface Area Catalyst Concentration I am going to find out if changing the concentration of nitric acid in water and see if it has any effect on
An investigation of neutralization reactions Aim Question : What is the effect of changing the concentration of an alkali, on the volume of acid needed to neutralise it, when acid is added to it? The plan is to use two acids (Hydrochloric & Sulphuric) and one alkali (Sodium Hydroxide). The reason I need to use two acids is; because the question applies to all acids and alkalis and to just use one of each would not enable me to come to a general conclusion. If there had been more
The Rate of a Chemical Reaction When Changing the Concentration of Hydrochloric Acid I am going to investigate the effect of the concentration of the acid solution, Hydrochloric acid to see how this changes the rate of reaction. For my experiment I will use sodium thiosulphate as my constant and I will be changing the concentration of hydrochloric acid and water. I predict that as the concentration of hydrochloric acid increases, the rate of reaction also increases. I also think that the
a difference between the water concentrations on the two sides of the membrane, and when this happens to cells they will either become turgid if water flows into them, or plasmolysed if water flows out of them, and therefore changing their mass. Aim: To investigate how changing concentration in a sugar solution affects the rate of osmosis in potato chips. Prediction: I predict that as potato chip is placed in a solution of high water concentration then the potato chips will increase
The Effect of Changing the Concentration of the Enzyme Catalyst on the Rate of Reaction on Hydrogen Peroxide Planning -------- Hydrogen Peroxide Water + Oxygen 2H2O2 2H2O + O2 Introduction - Background Information ------------------------------------- To help me understand what a chemical reaction is or involves I did some research. A chemical reaction is a process by which atoms or groups of atoms are redistributed, resulting in a change in the molecular composition of
Lab Report Testing the Effects of Changing Surcrose Concentration on Osmosis in Plant Cells Aim To investigate the effects of changing the sucrose concentration on osmosis in plant cells. Plan Water passes into cells through a special type of diffusion called osmosis. Water molecules diffuse through the membrane from a weak solution into a strong solution until the concentration is the same on both sides. A membrane that allows only certain molecules to pass through is called a semi-permeable
Between HCL and Marble Chips Planning I have decided to investigate the effect of different concentrations of hydrochloric acid on marble chips. I want to see how long it takes for 30cm of carbon dioxide to be given off once the acid and marble chips start reacting. I carried out a preliminary experiment to see what sort of time ranges I was going to expect because I wanted to get the concentration levels right otherwise I could have been waiting for a long time. I didn't have that sort of
The Rate Of A Reaction Between Hydrochloric Acid And Sodium Thiosulphate Aim: I am going to investigate the effect of changing the concentration of Sodium Thiosulphate on the rate of the reaction between Hydrochloric Acid and Sodium Thiosulphate. Prediction: I predict that as the concentration of the Sodium Thiosulphate doubles, the rate of the reaction will double. I believe that when the most concentrated solution is used the reaction would be at its fastest. Collision Theory: In
osmotic effect of changing the concentration of sucrose solution; distilled water, 20% sucrose solution, 40% sucrose solution, 60% sucrose solution on the change in mass of potato cylinder after 30 minutes of being in solution. Introduction- Osmosis is the movement of water molecules from a region of high Concentration to a region of low concentration through a semi-permeable membrane. If a plant cell is places in a hypotonic solution the cell has a lower water concentration to that of the solution
Aim: to find out how changing the concentration of acid by diluting it affects the rate of reaction. Planning: I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use 30ml of liquid made up of different concentrations of acid diluted with water. Introduction: I have decided to vary the concentration of the acid as my variable I could have chosen other variables to change such as changing the heat of the acid
Investigation Of Osmosis In Potatoes Aim: To investigate the affect of different concentrations of sugar solution on potato cells. Variables: The variables are; the concentration of sugar in the solution and the mass of the potato cylinder. We will measure the mass of a potato cylinder after a certain amount of time in a certain solution. Fair test: To keep the test fair we need to keep the controls the same. Like keeping the temperature the same so the kinetic energy doesn't
The Concentration of Sugar in the Cell Sap of a Potato Cell's Vacuole Plan In this experiment I am intending to investigate the concentration of sugar in the cell sap of a potato-cell's vacuole. I will discover this using my knowledge of the biological process of Osmosis. Osmosis is the movement of solvent (usually water) through a semi-permeable membrane separating solutions of different concentrations
findings follow my prediction, other than the 90% readings. According to my prediction, even with an inhibitor present the 90% concentration readings should have been higher than the 80% concentration readings. As stated above this could be because that the enzyme concentration is the limiting factor. But the figures actually drop from 80% concentration to 90%. This could be explained because there are so many substrate molecules competing for the active sites of the enzyme
The Effect of Salt Concentration on the Weight and Length of a Potato Chip I am trying to find out if and how different concentrations of salt solution affect the weight and length of a potato chip in a certain amount of time. This will involve me performing the experiment, measuring the potato cylinders weight and length before and after the experiment putting results in a table producing charts showing the differences or similarities in results analysing the results and finally evaluating
