Question

the solubility of glucose at 30°c is 125 g/100 g water. a solution is made by adding 250 g of glucose to 100 ml of water at 30°c. remember that 1 g water = 1 ml water. how would you classify this type of solution? heterogeneous saturated supersaturated unsaturated

Explanation:

Step1: Determine mass of water

Given 100 mL of water and 1 g water = 1 mL water, so mass of water $m_{water}=100$ g.

Step2: Find solubility - based amount of glucose

Solubility of glucose at 30°C is 125 g/100 g water. For 100 g water, maximum amount of glucose that can dissolve $m_{max}=125$ g.

Step3: Compare added and maximum - dissolvable glucose

Amount of glucose added $m_{added}=250$ g. Since $m_{added}>m_{max}$, the solution is supersaturated.

Answer:

supersaturated
