Question

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?

Answer 1

The dissolution of sodium chloride (NaCl) occurs most rapidly in the beaker with the highest temperature. Higher temperatures generally increase the kinetic energy of water molecules, which leads to more frequent and effective collisions between the water molecules and the salt, facilitating the dissolution process.

Given the information provided, the highest temperature is in Beaker D (60°C). Therefore, the dissolution of sodium chloride would occur most rapidly in Beaker D.

So, the correct response is:

Beaker D
