Chemistry Experiment On The Reaction Of Different Metals When Exposed To Acid

891 words - 4 pages

Before the experiment, I wrote down a prediction. My hypothesis towards the experiment was that magnesium would have a bigger reaction with the acids. The reactivity of an element depends on its ability to gain or loose electrons which are used for bonding. The more reactive an element, the more easily it will combine with others. From this information, I know that magnesium has a stronger ability to gain or loose electrons which makes the metal more reactive.

I gathered together four different metals and acid compounds which all reacted with one of the elements in the past, for example, Iron Sulphate (FeSO4) contain iron. I prepared equipment I would use for the experiment, such as a pipette to carry the acid in, tweezers to lift the metals in, trays to pour the acids in, etc.

I took an appropriate amount of acid and added in and the tray using the pipette. I then used the tweezers to pick up the metal with and add to the acid. I then observed all the reactions and noted down the effects.

In the experiment, there was a very obvious pattern and many effects on the metals that did react with the acid.
One very obvious pattern in the experiment would be that all the metals did not react with the acid compound that reacted with the same metal in the past, for example, iron did not react with iron sulphate. (Fe + Fe(SO4)2 = Fe + Fe(SO4)2)

Copper is the least reactive metal in the experiment because it is generally low in losing and gaining electrons. This is the main concept of reactivity because if a metal/element is weak in losing and gaining electrons then it is not very reactive, whereas if it is strong, it is more reactive. In all the acids, I observed that copper reacted with nothing.

Iron is the next least reactive metal carried out in the experiment. This is because it only reacted with copper sulphate. There was a reaction because Iron (Fe) was more reactive since it is better at losing and gaining electrons, so it displaced copper in the copper sulphate and it turned into Iron Sulphate + Copper (FeSO4 + Cu). I saw that the Iron changed colour after it tarnished in the acid. After looking at the less reactive metals out of the four, I focused on the reactivity of the other metals.

Magnesium is the most reactive metal in the experiment as I predicted. As explained, it was because of magnesium is very string when it comes to losing and gaining electrons. It reacted with the Copper sulphate, causing the magnesium to tarnish in the acid and turn black, losing its shiny appearance. It broke apart and...

2736 words - 11 pages indicator is concurrent with a color change or some other physical change which informs the observer of the solution's approximate pH. A decreased amount of H3O+ (a product of acid dissociation) makes it more probable for the dissociation reaction of the indicator to occur since equilibrium must be maintained. Depending on the specific dissociation constant of each indicator a different H3O+ concentration (and thus pH) will trigger the
