Indicate which aqueous solution has the fastest evaporation rate. A) 0.1 M KCl B) 0.2 M Na₂CO₃ C) 0.2 M NaCl D) 0.1 M MgCl₂ E) 0.2 M MgCl₂

Question

Quizplus · Accepted Answer

The evaporation rate of a solution is inversely related to its vapor pressure, which decreases with increasing solute concentration and number of ions. 0.1 M KCl has the lowest concentration and ion count, leading to the highest vapor pressure and fastest evaporation rate.
