For this data analysis project‚ I conducted and experiment to investigate how the concentration of an acid affects the rate of the reaction. I have set up the experiment’s equipment as shown on figure 1. As you can see by figure 1‚ I have used the reaction between sodium thisoulphate solution and hydrochloric acid (HCL) to come up with results that will help me draw conclusions regarding the effects of the concentration of the acid. I decided to use this particular reaction due to the fact that the

OUT OF COOKED BEETROOT? PLAN Hypothesis Temperature has an effect on the leaking of the colour from beetroot. This means that as the temperature is altered there will be a change in the rate of colour leakage. Scientific Background Beetroot is a very familiar vegetable and is commonly known as beet. It is famous in most recipe books that advice that its outer skin is not to be removed to avoid getting red dye in the cooking water. If we look at the internal structure of beetroot‚ it will be

Biology Coursework Hypothesis: To investigate the effect of different concentrations of ethanol on the permeability of beetroot cell membranes. Prediction: By exposing a membrane to a solvent‚ ethanol‚ it will increase its permeability. So the higher the concentration of the solvent‚ the more permeable the membrane will be. But if the concentration of the ethanol is beyond a certain limit‚ it may break down the cell membrane to the point where there is in fact no overall effect as the ethanol

What is Cancer? All living things are comprised of a variety of cells‚ such as kidney cells‚ brain cells and skin cells. Cancer develops when a particular cell mutates‚ then begins to grow and divide. Eventually‚ these cells form a mass called a malignant tumor‚ which often starts to invade surrounding tissue and organs. Super Foods It is thought that up to one third of cancer related deaths could be diet related. Many of the foods we eat today can in fact be harmful to the cells in our bodies

temperature to increase by adding table salt. The problem it is trying to explain is‚ how does table salt affect the boiling temperature of water? does it increase or decrease? or does it stay the same? Hypothesis After reading the lab instructions - but before starting the lab - record your best “educated guess” about what will happen in the experiment. What hypothesis can you generate about the effect of adding salt to water? Adding table salt to boiling water will cause the water to

Beet Root Membranes What is the affect of temperature on beetroot membranes? Hypothesis: It is hypothesized that as the temperature increases‚ the deeper red the beetroot water will be. At higher temperatures the proteins in the beetroot plasma membrane will denature‚ leaving holes in the membrane and allowing the red pigment in the cell sap to seep out into the water around it. Variables: Dependent-The dependent variable is the absorbency of the beetroot water after being soak at either

Does concentration affect the speed of chemical reactions? Problem: We are proving that “concentration” (the amount of reactants) is one of the things that can affect the speed of chemical reactions. We are also finding a way to keep the lid on the film canister for the longest period of time. We are using vinegar and water as reactants and changing the concentration every time to see the difference between the rates of reactions speed. Materials: - 1 graduated cylinder - 1 film canister
