Question

the table below compares the solubility of two substances in 100 milliliters (ml) of water.
solubility of substances

solubility temperature	sucrose grams/100ml water	hydrochloric acid grams/100ml water
solubility at 100°c	488	989

based on the table, which of the following statements is true?
o the solubility of sucrose increases if more is dissolved.
o the solubility of sucrose decreases as temperature increases.
o the solubility of hydrochloric acid increases if more is dissolved.
o the solubility of hydrochloric acid increases as temperature increases.

Explanation:

Step1: Analyze sucrose solubility

The solubility of sucrose at 20°C is 204 grams/100mL water and at 100°C is 488 grams/100mL water. So, its solubility increases with temperature. Also, solubility is a property of the substance - temperature relationship and not affected by the amount dissolved once the conditions are set.

Step2: Analyze hydrochloric - acid solubility

The solubility of hydrochloric acid at 20°C is 720 grams/100mL water and at 100°C is 989 grams/100mL water. This shows that its solubility increases as temperature increases and is not affected by the amount dissolved.

Answer:

The solubility of hydrochloric acid increases as temperature increases.
