Malachite Lab Report

When measuring out the copper sulphate during the Malachite experiment, the first thing that was noticed was the light blue colour on the powder. This colour became brighter and more vibrant after the distilled water was added. In a separate beaker, the sodium hydrogen carbonate when combined with the distilled water was white in colour. After both the solutions in the two beakers were stirred on the hotplate and combined, the solution released a lot of carbon dioxide which formed bubbles. In addition to this, the solution turned into a brighter shade of blue. The shade is dependent on the pH levels and speed of experiment and is very much influenced by the crystal structure of the chemicals. In historical paintings, the pigment tends to look
