Verified step by step guidance1
Understand the question is asking for the term that describes how well a substance can dissolve in water.
Recall that 'Molarity' refers to the concentration of a solution, specifically moles of solute per liter of solution, not the ability to dissolve.
Recognize that 'Conductivity' relates to a solution's ability to conduct electricity, which depends on the presence of ions, not directly on dissolving ability.
Know that 'Reactivity' describes how readily a substance undergoes chemical reactions, which is different from dissolving in water.
Identify that 'Solubility' is the correct term because it specifically measures the extent to which a substance can dissolve in a solvent like water.
