    Investigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

  • Paddle Pop Stick 2 Co 3 Flame
    663 words
    Experiments to determine the identity of metals by examining the colour of flame when samples of that metal are heated. The aim of this experiment was to find out whether different metals had different reactions when subjected to the flame of the Bunsen burner. This might then allow the classification and identification of certain metals if they have their own reactions, which will be different coloured flames for this experiment. It was hard for me to predict what would occur during the experim...

    Bunsen Burner In class on Monday. We learn how to use a Bunsen burner. We had to tell what was the hottest and coolest part of the flame. When we finish that. We had to take a wire and go up and down in the flame to see what was the hottest part of the flame. After we did that, we had to take a evaporating dish, and put it into the flame and see what would be collected on the dish. To hook the Bunsen burner up. We had to connect the burner to a gas jet with the rubber hose that was hook to the b...

  • Bunsen Burner Graduated Cylinder
    791 words
    Qualitative Analysis of Cation Introduction: The purpose of this experiment is to demonstrate the separation and identification of metal ions based on the insolubility of certain salts. The solubility rules should be taken into account. If a solution dissolves in water, the result contains both cations and anions. Analyzing different ions to discover their nature is the main goal of this experiment. Separation of the cations by testing the differences in solubility of different metal salts is do...

  • Bunsen Burner Degrees Celsius
    1,031 words
    Aim: Dunder Experiments Experiment 1. Aim: To find the PH of Dunder. Materials: -Crucible -Filtrated Dunder -Universal Indicator -Eyedropper Method: A small amount of filtrated Dunder is placed in the Crucible. A few drops of Universal Indicator are then dropped onto the Dunder with the Eyedropper. The mixture will then change to colour corresponding to the Dunder's PH. Results: In this Experiment the PH of the Dunder came up as 4. This showed that Dunder is considerably acidic. Experiment 2. Ai...

  • Rate Of Reaction Bunsen Burner
    2,301 words
    For this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme Amylase can only break down starch to dextrin. I am going...

  • Bunsen Burner Hydrochloric Acid
    762 words
    The 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...
