    An experiment to investigate the effect of changing the concentration of hydrochloric acid on the rate of reaction with sodium thiosulpahte. Aim I am trying to find out how the concentration of hydrochloric acid affects the reaction time with sodium thiosulpahte. If a clear solution of sodium thiosulphate is mixed with hydrochloric acid then a reaction will occur where a creamy-yellow precipitate of sulphur is produced. H20 Text Box: + Text Box: + Text Box: + Na2S203 2HCL

  • The Effect of Changing the Concentration of Sucrose on the Movement of Water into a Potato

    764 Words  | 4 Pages

    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

  • The Effect of Changing Solute Concentration on Osmosis in Potato Tissue

    1986 Words  | 8 Pages

    The Effect of Changing Solute Concentration on Osmosis in Potato Tissue Aim The aim of the investigation is to find out the effect of changing solute concentration on osmosis in potato tissue. Prediction I predict that if the solute solution is more concentrated than the potato, the potato chip with the more water potential will lose water, so if the potato chip is placed into a dilute solute solution, the potato will gain water. Here's the example- if the original cells is 5g then

  • The Effect of Changing Concentration of Hydrochloric Acid on Its Reaction with Carbon Dioxide

    1123 Words  | 5 Pages

    The Effect of Changing Concentration of Hydrochloric Acid on Its Reaction with Carbon Dioxide Plan Carbonates, including all forms of limestone, react with hydrochloric acid to produce Carbon Dioxide: Calcium ┼ Hydrochloric → Calcium ┼ Water ┼ Carbon Carbonate Acid Chloride Dioxide I'm going to experiment with changing the concentration of the hydrochloric acid in this reaction and seeing how it affects the amount of Carbon Dioxide that is produced. I predict that the amount

  • The Affect of Changing the Concentration on the Rate of Reaction

    1086 Words  | 5 Pages

    The Affect of Changing the Concentration on the Rate of Reaction To find out the affect of changing the concentration on the rate of reaction Scientific background Collision theory: Collision theory explains how chemical reactions occur and why rates of reaction differ. For a reaction to occur, particles must collide. If the collision causes a chemical change it is referred to as a fruitful collision and it's a Theory that explains how chemical reactions take place and why rates of

  • How changing the concentration changes the rate of reaction.

    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 experiment to find out how changing the concentration of acid

    1113 Words  | 5 Pages

    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

  • Investigation Into The Effect Of Changing The Substrate Concentration On The Enzyme Catalyse

    1019 Words  | 5 Pages

    Investigation Into The Effect Of Changing The Substrate Concentration On The Enzyme Catalyse Introduction ============ I am experimenting the effect of substrate concentration on the action of the enzyme catalyse. I will investigate this by experimenting to see how long it takes to fill a test tube full of the gas from the reaction, which is oxygen. I will use different amounts of catalyse in the form of yeast to test how long it takes to fill the test tube with oxygen, which is one

  • The Rate of a Chemical Reaction When Changing the Concentration of Hydrochloric Acid

    1175 Words  | 5 Pages

    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

  • Investigating How Changing the Concentration of Sucrose Affects Its Reaction Time

    1688 Words  | 7 Pages

    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
