    But-2-enedioic acid Introduction Cis-trans isomers are a kind of stereoisomers called geometrical isomers. Due to the inability of rotation about the C=C bond‚ some compounds possess cis and trans isomers. But-2-enedioic acid is an example of having both isomers. Maleic acid Fumaric acid Cis and trans isomers have different physical properties such as boiling point‚ solubility‚ density and stability. In this experiment some maleic acid is converted to fumaric acid by

    done we had to add all five blocks in to the test tube with the acid and time to see how long it would take for the colour to change from a pinky purple to clear. From this experiment I learnt that the bigger the size of the jelly is the more time its going to take for the colour change to take place‚ the colour change represents the rate of diffusion‚ the smaller the block of jelly is the less time its going to take for the colour change to take place which means the rate of diffusion

    plates -KMnO4 crystals -methyl orange -refrigeration -ruler The experiment requires 4 plates of agar due to his transparency and the colloid that forms when mixed with water. One pair of plates is labeled 4^0 C and the second pair RT (room temperature). After taking the lids of the first pair ‚using a tooth pick‚ a small crystal of potassium permanganate is placed in the center of the of the agar and the same amount of methyl orange. The same process is repeated for the second pair. The first

    results that have been gathered‚ it tells a variety of different things. Each temperature attempt was done three times to be accurate. First of all‚ the hypothesis (the higher the temperature the faster the reaction will occur) has been proven correct and it proves the theory right. From the results‚ we can see this‚ as the iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1
