Water is a homogeneous mixture of nitrogen, oxygen and smaller amounts of other compounds in the gaseous materials. Stay tuned with BYJU’S to learn more interesting topics in Chemistry.
Another mixture of dyes is called universal indicator. This is more useful than litmus as it can be used to measure how strong an acid or an alkali is using the pH scale. A pH of 7 is neutral (like for example water); a pH of 1 or 2 is a strong acid (for example sulfuric acid); weak acids like vinegar have a pH of 3 to 6.
