Question

1. experiment on rate of dissolution students add salt to four beakers of water and use a magnetic stirrer rotating at different speeds to dissolve the salt. which factor affecting the rate of dissolution is being tested? a. temperature b. agitation c. surface area d. concentration

Explanation:

The experiment involves varying the speed of a magnetic stirrer, which directly relates to the mechanical mixing (agitation) of the solution. Agitation is a known factor affecting dissolution rate by enhancing contact between solute and solvent.

Answer:

B. Agitation
