Reactivity of Mg and Ca Essay

IntroductionThe aim of this pragmatical is to observe the difference in the reactivity among Mg and Ca when sultry and cold pee is added.HypothesisWe theorise they will react in roughly kind of form.VariablesThe independent shifting was the temperature of the weewee and also the quantity of metal engross in the experiment and the dependent variable was the reception.Equipment* Mg (s)* Ca (s)* Phenolphthalein* Beaker* bleak and animated peeing* Sandpaper* Test tubes with embraceProcedure1. The Magnesium was cleaned with sandpaper.2. twain pieces of magnesium was put into devil riddle tubes and two pieces of calcium was put into two adjudicate tubes.3. Cold water was added into two test tubes one with calcium one with magnesium.4. Two droplets of phenolphalein were added in each of the test tubes fill with cold water to observe the switch in ph.5. Water was heated everywhere a Benson burner and poured into the two test tubes without water while observing the che mical reactions.6. Two droplets of phenolphalein were added in each of the test tubes filled with cold water to observe the change in ph.ObservationRelative reactivity ofCold waterHot waterMgThere was a minimum reaction. Fig. 1There is a bigger reaction than with the cold water. Fig. 2CaThe temperature of the water increases right away. in front we dropped the phenolphthalein the solution was white, fig.3, solely after adding the phenolphthalein it sour beg, fig.4, which means that the reaction is basic.The temperature stayed the same but because the water was glowing the reaction was more explosive and quicker. Before the phenolphthalein the solution was white, fig.3, and after dropping the phenolphthalein it turned pink, fig.4, which means that is a basic solution.Results be your results in accordance with what you run through intentional about reactivity?Yes because calcium has more orbits the atom has the less energy it needfully to give away electrons. In this chemise the atom that has more orbits is the calcium that is why it reacts more than the magnesium because calcium demand less energy to give electrons away. And the magnesium didnt react much because it postulate more energy that the one that we gave it. economize the balanced equation for the reaction between Mg and pissMg (s) + H2O (l) MgO (s) + H2 (g)UncertaintiesOther element might give up been present.The hot water might have been heated more.ConclusionWe learned that two magnesium and calcium is basic solutions because of the pink tint to the color. We also learned that calcium reacted faster than magnesium.
