Turbidity - GCSE Chemistry Definition

Turbidity is a measure of how clear or cloudy a liquid is, caused by tiny particles floating around in it. In GCSE Chemistry, we learn that when there are lots of tiny particles in water, like bits of dirt or algae, the water becomes murky or cloudy, which means it has high turbidity. Clear water, on the other hand, has low turbidity because it has fewer or no particles. Turbidity is important because it can affect the quality of water for drinking, living organisms, and even for chemical experiments. Scientists use special instruments to measure turbidity and check that water is clean and safe to use.
