According to the provided reference, yes, chalk powder is soluble in water.
Based on the specific information given, which states, "Sand and chalk powder are soluble in water," we can conclude that chalk powder dissolves when mixed with water.
Understanding Solubility
Solubility refers to the ability of a substance (the solute) to dissolve in another substance (the solvent), forming a uniform mixture called a solution. When a substance is soluble, its particles disperse throughout the solvent, often disappearing from view.
What Happens When Something Dissolves?
- The solvent particles surround and separate the solute particles.
- The solute particles spread out evenly within the solvent.
- A homogeneous mixture is formed.
If a substance is insoluble, it does not dissolve; instead, it may settle at the bottom, float, or remain suspended as separate particles, forming a heterogeneous mixture.
Chalk Powder and Solubility
The reference clearly indicates that chalk powder is a substance that exhibits solubility in water. This means that when chalk powder is added to water, it will dissolve.
Example of Solubility
Think about adding sugar to tea. The sugar disappears as it dissolves, making the tea taste sweet throughout. This is an example of solubility. According to the reference, chalk powder behaves similarly in water.
Comparing Solubility
Different substances have varying degrees of solubility. Some dissolve easily, while others dissolve very little or not at all.
Here's a simple comparison based on the reference:
| Substance | Solubility in Water (According to Reference) |
|---|---|
| Sand | Soluble |
| Chalk Powder | Soluble |
Practical Aspects
When dealing with materials, knowing their solubility is important for various applications, such as:
- Separation: Soluble substances can be separated from insoluble ones by dissolving one component and then filtering the mixture.
- Mixtures: Solubility determines whether two substances will form a solution or simply a mixture where particles remain distinct.
- Reactions: Many chemical reactions occur only when reactants are dissolved.
Based on the reference, chalk powder would be treated as a soluble substance in these contexts.
