Solubility of a substance depends on:

• A. Nature of solute
• B. Nature of solvent
• C. Temperature
• D. All of the above

The solubility of a substance is influenced by several factors. Let's break them down:

Factors Affecting Solubility

• Nature of Solute: Different substances have unique properties that affect how well they dissolve. For example, ionic compounds typically dissolve well in polar solvents like water.
• Nature of Solvent: The solvent's characteristics, such as polarity, play a crucial role. Polar solvents dissolve polar solutes, while non-polar solvents are better for non-polar solutes.
• Temperature: Generally, increasing the temperature can enhance the solubility of solids in liquids, while gases may become less soluble as temperature rises.

Final Thoughts

Considering all these factors, the correct answer to your question is D. All of the above. Each aspect contributes to how well a substance can dissolve in a given solvent.
