Question
solutions and solubility
a chemist dissolved crystals of an unknown substance into water at room temperature. he found that 33 g of the substance can be dissolved into 100 ml of water. what property of the unknown substance was the chemist most likely investigating?
its solubility
its rate of dissolution
its chemical reaction to water
its reaction to temperature changes
La solubilidad se define como la cantidad máxima de un soluto que puede disolverse en un solvente (en este caso, agua) a una temperatura dada (temperatura ambiente). El hecho de que el químico determinara la cantidad de sustancia (33 g) que se disuelve en 100 mL de agua se ajusta a la definición de solubilidad. El "rate of dissolution" se refiere a cómo rápido se disuelve (no la cantidad), la "chemical reaction to water" implicaría un cambio químico (no solo disolución) y "its reaction to temperature changes" no se menciona (se especifica temperatura ambiente).
