Question

12 fill in the blank 1 point to what temperature must a solution of 50 g of kcl in 100 g of water be raised to for all the kcl to dissolve? answer 65°c 50°c 90°c 85°c 75°c previous

Explanation:

Step1: Recall solubility data

The solubility of KCl in water varies with temperature. We need to refer to a solubility - temperature table for KCl.

Step2: Find the temperature for 50 g KCl in 100 g water

From the solubility - temperature table of KCl, we know that approximately 50 g of KCl can dissolve in 100 g of water at around 85°C.

Answer:

85°C
