Favorite Corrosion Of Metals Experiment

Metals situated below iron on the table of standard electrode potentials can function as sacrificial metals.

Corrosion of metals experiment. Design an experiment to test 4-5 metals under different conditions for corrosion including a salt solution. In this experiment we are looking at the initial product only. Youll test five metals-silver steel zinc copper and aluminum-to see which corrodes fastest in water and in salt water.

Some commonly used techniques for measuring and preventing corrosion will bestudied. Steel corrosion produces a variety of iron oxides depending on conditions. In this experiment we are going to compare the corrosion of three different metals in three different environments over a period of three weeks.

Our focus will be corrosion of iron but the problem is not limited to iron-based structures. Materials metals wear away. The final product of iron oxidation rust is usually a ferric oxide often hematite Fe 2 O 3.

In this experiment students can observe several of these factors. But in practice the word corrosion is mainly used in conjunction with metallic materials. The samples need to be kept in a safe location for this period.

The least corrosion occurred in the aluminium foil placed in salt water. This experiment investigates how acids affect the rate of corrosion as we compare it to rainwater and acid rain models. Due to it being placed in a liquid such as water or acidic liquids.

The liquid remained the same but very tiny holes were observed in the metal. Total corrosion was evident as the aluminium foil disintegrated into fine pieces which nearly got dissolved in the vinegar. Helpful informationdata Reactivity of Metals tables show reaction of metals with water acids oxygen in air but not salt.
