Heating salt water experiment
WebIntroduction Epsom salt (MgSO 4 ·7H 2 O) is a heptahydrate of magnesium sulfate: within one mole of magnesium sulfate heptahydrate are seven moles of water. This water can be driven off by heat to form the anhydrous (dehydrated) ionic compound, magnesium sulfate. WebIn this experiment, a known mass of hydrated copper(II) sulfate is heated to remove the water of crystallisation. The mass of water is found by weighing before and after heating. This information is used to find x in the formula …
