Objective:
To find out what acid and metal will form after they react
Introduction:
Acids are substances which release hydrogen ions in an aqueous solution. They have a sour taste, examples such as lemons, vinegar, or even the digestion fluid in our stomach. What do acids do? They contain hydrogen ions; they release these ions when reacting with other substances and form new products. Many metals and substances react with acids, and the reaction in between is like this:
Acid + Metal oxide (Metal hydroxide) Salt + Water
Acids + Carbonates Carbon dioxide + Salt + Water
Acids + Metals Salt + Hydrogen
I am going to investigate the reaction of an acid and a metal in this experiment. I am going to test with two very common acids, hydrochloric acids, which are contained in our stomach digestion fluid, and ethanoic acids, which are known ad vinegar as well. The reactants I am going to use are Magnesium ribbon, which is a metal, marble chip, which contain carbonate, and Copper Oxide, which is a metal oxide. According to the three chemical formulas of acids' reactions above, I predict these three kinds of chemicals will form a salt and water, carbon dioxide and salt and water, salt and hydrogen respectively, when they react with the acid.
An acid can be strong or weak. Strong acids dissociates very well in water, releasing hydrogen ions, in other words they are very corrosive and can dissolve other substances very well. A weak acid is safer and doesn't dissociate well, they contain less hydrogen ions as well. I am going to test with the strong hydrochloric acid, and the weak ethanoic acid. Acids can have different concentrations of water and acid. A dilute acid has a lot of water and not much acid. A concentrated acid has a lot of acid and not much water. Therefore dilute acids are less corrosive than concentrated acid because they contain more water and less acid.
