A student arranges an investigation to examine the variables influencing the solubility of sodium chloride. The student introduces 5.0g of sodium chloride into four separate beakers, each holding 250 mL of water. Next, the student positions the beakers on distinct hot plates and elevates their temperatures to the subsequent levels:
Beaker A: 30°C
Beaker B: 40°C
Beaker C: 50°C
Beaker D: 60°C
In which of the beakers would the dissolution of sodium chloride occur most rapidly?
The dissolution of sodium chloride would occur most rapidly in the beaker with the highest temperature, which is Beaker D at 60°C.
explain
The solubility of a solute, in this case sodium chloride, generally increases with increasing temperature. This means that as the temperature of the solution increases, more sodium chloride will be able to dissolve in the water.
In the given scenario, Beaker D has the highest temperature of 60°C. Therefore, the solubility of sodium chloride in Beaker D is the highest among all the beakers. This means that sodium chloride will dissolve more rapidly in Beaker D compared to the other beakers with lower temperatures.
In summary, the dissolution of sodium chloride would occur most rapidly in Beaker D, where the temperature is the highest.
The following table displays four solutions created through the dissolution of salt in water.
