A solute is any substance that is dissolved in another substance, which is called the solvent. A student tested the solubility (a measure of how much solute will dissolve into the solvent) of six different substances. The solubility of a substance at a given temperature is defined as the concentration of the dissolved solute that is in equilibrium with the solvent. Table 1 represents the concentration of dissolved substances in 100 grams of water at various temperatures. The concentrations are expressed in grams of solute per 100 grams of water.The data shown in table 1 support the conclusion that, for a given substance as the temperature of the water increases, the amount of solute that can be dissolved
Correct answer: C. Varies but with a trend depending on substance
- A. Increases only
- B. Decreases only
- C. Varies but with a trend depending on substance
- D. Varies but with no trend
Explanation
The best answer is C. It is clear from the table that each substance reacts differently in its solubility depending on the temperature. However, each substance does show a clear trend in whether it gets more or less soluble with increasing temperature.
