Reactivity of magnesium in water. Two test tubes containing magnesium and the indicator phenolphthalein. The left hand test tube also contains hot water,while the right hand test tube also contains cold water. The magnesium reacts with the water,creating magnesium hydroxide. It is this that causes the phenolphthalein to change to a pink colour. Both reactions were started at the same time. As shown by a greater change in colour,the reaction is faster in hot water | |
