Question 25
In this experiment, you will heat water and try to dissolve more salt in the water as the temperature increases. Three separate beakers each start with 50 cm³ of water; investigate sodium chloride, magnesium sulfate and copper sulfate separately. Record the mass dissolved at 20°C, 40°C, 60°C and 80°C for each salt, using your own measured results.
What did you notice as the solutions cooled?
