Colours have an influence on our moods, and our actions. Therefore, in presenting chemical experiments, we aim to include visually appealing ones. We will delve into more straightforward experiments, demonstrate the hidden colours in seemingly unattractive substances, proceed to slightly more complex redox reactions and coordination chemistry, and explore the colourful diversity of chemical compounds.
Changes in pH can affect a variety of chemical processes, therefore accurate determination is important for understanding the properties of substances. Red cabbage contains large amounts of substances called anthocyanins. These are water-soluble dyes that change colour in different pH environments and for that reason red cabbage can be used as a natural pH indicator. Cabbage is also a good…
