Aluminum reacts with hydrochloric acid. Aluminum is extremely reactive and undergoes several reactions. However, if one were to put a piece of aluminum foil in a beaker of hydrochloric acid, there may not be a reaction because of the oxide coating electrolytically applied during production. The reaction will occur with pure aluminum shavings.Continue Reading
When aluminum is placed in a beaker of hydrochloric acid, the reaction produces hydrogen gas and aqueous aluminum chloride. The balanced chemical equation for the reaction is 2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g). This experiment can be done safely, but safety goggles should always be worn when working with corrosive acids.
The reaction produces two moles of aluminum chloride and three moles of hydrogen gas. The aluminum donates its valence electrons to become more stable by connecting with chloride. This is a chemical change because aluminum is transformed into a different compound. A chemical change occurs when compounds react to form new compounds. This reaction is known as a single displacement reaction because aluminum trades places with the hydrogen.
Aluminum is one of the most abundant elements on Earth. It comprises approximately 7% of the Earth's crust. The oxide layer that aluminum forms makes the metal resistant to corrosion.Learn more about Atoms & Molecules
Aluminum reacts with oxygen to form a layer of aluminum oxide on the outside of the metal, according to HowStuffWorks. This thin layer protects the underlying metal from corrosion caused by oxygen, water or other chemicals. Aluminum burns in oxygen with a white flame to form the trioxide aluminum (III) oxide, says WebElements. Chemists write the chemical reaction between aluminum and oxygen as: 4Al+ 3O2 = 2Al2O3.Full Answer >
The melting point of a 10 percent solution of hydrochloric acid is -18 degrees Celsius, while the melting point of a 20 percent solution is -59 degrees Celsius. The melting point varies based on the concentration of the solution.Full Answer >
The chemical reaction between hydrochloric acid and magnesium produces magnesium chloride and hydrogen gas. The balanced chemical equation for this reaction is Mg (s) + 2 HCl (aq) produces MgCl2 (aq) + H2 (g), where the letter "s" stands for solid, "g" is gas and "aq" represents an aqueous solution.Full Answer >
The main uses of hydrochloric acid include the production of fertilizers, dyes and electroplating. Hydrochloric acid is also utilized in the production of rubber products and textiles. One of the most important uses of hydrochloric acid is the pickling of steel.Full Answer >
