Question

. Record your results for the four solubility temperatures of KCl as follows: a Temperature at which the solubility is 3.5g / 10 mL (C) b Temperature at which the solubility is 4g / 10mL (C) c Temperature at which the solubility is 4.5g / 10mL (C) d Temperature at which the solubility is 5g / 10mL (C) 2. Convert your grams/10 mL values to grams/100 mL values and plot a solubility curve for potassium chloride. The horizontal axis is the temperature scale from 20 to 80C using 10-degree intervals, and the vertical scale is the solubility in g/100 mL.

Explanation / Answer

A) Temperature at which the solubility is 3.5g / 10 mL =23.1 C

4g / 10mL (C) =39.8 C....4.5g / 10mL=56.8 C ,,5g / 10mL =74.8 C

B) 3.5g/10ml = 35g/100ml temp = 23.1 C

4g/10ml = 40g/100ml temp = 39.8 C

4.5g/10ml = 45g/100ml temp = 56.8 C

5g/10ml = 50g/100ml temp = 74.8 C
