Single Displacement Reaction
The objective of this experiment was to observe evidence of a reaction and to determine the chemical equation, if there is a reaction. In order for a reaction to occur, a metal strip must have evidence of black or grey deposits on the surface of the metal once dipped into the solution. The reactivity of an element is related to its tendency to lose or gain electrons. Three metal strips that were used are copper, lead and zinc as well as the solutions of silver nitrate, copper(II) nitrate, lead(II) nitrate, magnesium sulfate and dilute(3M) sulfuric acid. The copper metal strip was placed in the silver nitrate and dilute(3M) sulfuric acid, the lead metal strip was placed in the copper(II) nitrate and the zinc metal strip was placed in the lead(II) nitrate, magnesium sulfate and dilute(3M) sulfuric acid. Overall, putting these different strips of metal into different solutions will help determine the reactivity of copper, lead, zinc, magnesium, silver and hydrogen….
We then observe if there are any evidence of reaction which would be bubbling or appearance of metallic deposits on the surface of the metal stip.
