Copper sulphate experiment Introduction There are a number of different methods of making salts‚ such as the reaction of a metal with an acid. Copper metal‚ however‚ does not react with sulphuric acid and so another method must be used. In this experiment a basic copper compound (copper(II) oxide) will be reacted with sulphuric acid giving copper(II) sulphate as one of the products. Method 1. Wear goggles and keep your face away from the beaker during the reaction 2. Place 20 cmm3 sulphuric

The Jewish Chronic Disease Hospital‚ The Tuskegee Syphilis experiments‚ and the Hepatitis studies at the Willowbrook State School‚ are a few examples of highly unethical research studies that have previously been conducted. Willowbrook State School may be one of the hardest to consider ethically‚ because it involved

The Cabbage Indicator Experiment My hypothesis for this experiment is if I put an acid or a base in to a neutral then it will change colors. My hypothesis was correct in assuming that it would change colors with different substances or mixtures. If I put an acid or a base in to a neutral then it will change colors. The red cabbage indicator did change colors. Greens for bases and reds and pinks for acids. An alternative hypothesis for this could be “If the red cabbage indicator is purple then adding
