Question
Josh is making homemade lollipops. The recipe calls for dissolving 400 g sugar in 100 g of water. His friend, Alex, said that would never work because sugar’s solubility is 204 g per 100 g of water at 20°C. Despite Alex’s doubts, Josh successfully dissolves all 400 g of the sugar.
What did Josh do that allowed him to dissolve that much sugar in only 100 g of water?
Josh used sugar cubes instead of granulated sugar.
Josh used a pan with a large surface area.
Josh stirred the solution.
Josh heated the water.

Josh heated the water. Heating the water increases the solubility of sugar, allowing him to dissolve more than the typical solubility limit at room temperature. By raising the temperature, he was able to successfully dissolve all 400 g of sugar in the 100 g of water.
