identify the points where the solubility of kno3 is greater than 80 g per 100 g of h2o.
identify the points where the solubility of kno3 is greater than 80 g per 100 g of h2o.
Answer
Explanation:
Step1: Locate KNO3 curve
Find the curve representing KNO3 on the solubility - temperature graph.
Step2: Identify solubility value
Look for the points on the KNO3 curve where the solubility (y - axis value) is greater than 80 g per 100 g of H2O.
Step3: Determine temperature range
Observe the corresponding temperature (x - axis values) for those points. From the graph, the solubility of KNO3 is greater than 80 g per 100 g of H2O at temperatures above approximately 50°C. The points on the KNO3 curve above the horizontal line at solubility = 80 g per 100 g of H2O are the required points.
Answer:
The points on the KNO3 curve where the temperature is above approximately 50°C.
