To dissolve 30 grams of Chemical X in 1 liter of water at 45°C, Irina could improve the solubility by increasing the temperature of the water, as solids typically dissolve better at higher temperatures.
According to the solubility data provided, if the solubility of Chemical X at temperatures above 45°C is higher than at 45°C, then:
**B. She could increase the temperature of the water to 55°C.**
This would enhance the solubility of Chemical X, allowing more of it to dissolve into the water more quickly.
Option A (reducing the temperature) would decrease solubility further and would not help dissolve the crystals. Option C (refraining from stirring) would not be effective either, as stirring generally helps to increase the rate of dissolution by facilitating contact between the solute and solvent.
