What is water solubility?

Explanation:
Solubility describes how much of a substance can dissolve in a solvent under certain conditions. When we talk about water solubility, we’re asking how well a substance can dissolve in water. It’s about the amount that can dissolve at equilibrium at a given temperature, not how fast the dissolution happens. Temperature can affect solubility because it changes how molecules interact and mix. That’s why the statement “the ability to dissolve in water” is the best description. The other options refer to different properties: the rate at which water boils is about vaporization, the pH of water concerns acidity/basicity, and the density of water is mass per volume. None of those define solubility.
