AQA Science Exam Question and Answer
Question:
In the context of science, what is "colouring," and how can it be used in investigations to differentiate between different substances or identify specific characteristics?
Answer:
In science, "colouring" refers to the process of adding dyes, pigments, or indicators to substances to alter their visual appearance. Colouring substances can be used in various investigations and experiments to differentiate between different materials or identify specific characteristics.
For example, in chemistry, colour indicators are often employed to determine the pH level of a solution. These indicators change colour based on the acidity or alkalinity of the solution, allowing scientists to identify its pH value without the need for complex equipment.
In biology, staining is a common technique used to enhance the visibility of cells or tissues under a microscope. By applying specific dyes to biological samples, scientists can distinguish different cell types, observe cellular structures, and identify abnormalities.
In materials science, adding colouring agents to polymers or other materials can aid in distinguishing between various components or tracking their distribution in a product or sample.
Overall, colouring substances in scientific investigations offer valuable visual cues, enabling researchers to differentiate between substances, identify specific characteristics, and gain deeper insights into the properties of materials and substances.
