FAQs on Can water dissolve any amount of substance? Video Lecture - Science Class 6

1. Can water dissolve any substance?
Ans. Water is known as the "universal solvent" because it has the ability to dissolve many substances. However, it cannot dissolve every substance. Some substances, such as oil and wax, are not soluble in water.
2. What determines whether a substance can be dissolved in water?
Ans. The solubility of a substance in water depends on its chemical composition and the nature of its particles. Substances that are made up of small particles and have a similar polarity to water are more likely to dissolve in it.
3. Is there a limit to the amount of substance that water can dissolve?
Ans. Yes, there is a limit to the amount of substance that water can dissolve. This limit is known as the solubility limit. Once the solubility limit is reached, no more of the substance can dissolve in the water.
4. Can water dissolve gases?
Ans. Yes, water can dissolve gases. Some gases, such as oxygen and carbon dioxide, are soluble in water. This is why fish can breathe in water, as they extract oxygen dissolved in the water through their gills.
5. Are there any factors that can affect the solubility of a substance in water?
Ans. Yes, there are several factors that can affect the solubility of a substance in water. Temperature, pressure, and the presence of other solutes can all influence how much of a substance can dissolve in water.
