Chemistry Experiment on the Reaction of Different Metals When Exposed to Acid
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 …show more content…
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 turned into a powder like substance. When the magnesium reacted with the Iron sulphate the metal started to bubble and fizz causing a chemical reaction. Magnesium with magnesium nitrate had no reaction because a metal is never able to displace itself which caused no reactivity with the acid. This is the same reason no metal can react with an acid that has already reacted with it, because for example, iron can never displace iron sulphate. With the Zinc sulphate, the magnesium partly turned black but it was a slow reaction which did not happen straight away.
Zinc was the second most reactive metal because it reacted with two acid compounds. Copper Sulphate and Magnesium Nitrate. With Copper sulphate, the outer layer of the metal turned black. The metal became softer and weaker
