What would be the freezing point of a 1 m solution of HCl in water (K_f= 1.86 $\circ$ C)? A)0.0 $\circ$ C B)(-1.86 $\circ$ C) C)(-3.72 $\circ$ C) D)1.86 $\circ$ C E)(-0.93 $\circ$ C)

Question

Quizplus · Accepted Answer

The freezing point depression constant for water is 1.86°C/m. A 1 m solution of HCl in water would have a freezing point depression of 1.86°C. Therefore, the freezing point of the solution would be 0°C - 1.86°C = -1.86°C. However, the freezing point cannot be negative, so it is important to take the absolute value, resulting in a freezing point of 1.86°C - 0°C = 1.86°C. Answer choice C, (0°C - 3.72°C) = -3.72°C, the absolute value of which is 3.72°C, is the only answer choice that is the correct absolute value of the freezing point depression.
