Question 26
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.
Based on your observations, what relationship did you notice between the increase in temperature and the amount of salt that you could dissolve?
