Question

10 the graph below illustrates the solubility of potassium chloride (kcl) in water at a variety of temperatures. at what temperature does 30 g of kcl dissolve in 100g of water? solubility of kcl enter your answer in the space below

Explanation:

Step1: Locate the solubility value on the y - axis

Find the point corresponding to 30g on the "Solubility (g/100g water)" (y - axis).

Step2: Draw a horizontal line to the curve

From the 30g mark on the y - axis, draw a horizontal line until it intersects the solubility curve of KCl.

Step3: Draw a vertical line from the intersection to the x - axis

From the intersection point of the horizontal line and the curve, draw a vertical line down to the "Temperature (°C)" (x - axis).

Answer:

\(20^{\circ}C\)
