LibreTexts: Reactions of Group 2 Elements with Acids. You get hydrochloric acid when you dissolve hydrogen chloride into water at percentages up to around 40 percent HCl. How the COVID-19 Pandemic Has Changed Schools and Education in Lasting Ways. A metal's ability to react with HCl depends upon the metal's so-called activity, where metals with high activity react with HCl. The Reaction of Metals with Dilute Acid.. Potassium, sodium, lithium and calcium all react violently with dilute sulfuric acid and dilute hydrochloric acid. a. Is mercury metal or nitric acid the oxidizing agent? When aluminium is placed in an acid it may initially appear not to react. The effects of sulfuric acid on metal depend on a number of factors, including the type of metal, the concentration of the acid, and the temperature. Actually several of these will react with HCl, like copper metal. When metals and acids combine, the acids bubble up, releasing hydrogen gas. i. Metal refiners, for example, use this process to produce extremely high purity gold — like that found in bullion coins -- gold or silver coins that are kept safe as an investment, rather than being used as ordinary currency. 1 decade ago. The general equation that describes the chemical reaction between an acid and metal is metal + acid = salt + hydrogen gas. Chemistry. The U.S. Supreme Court: Who Are the Nine Justices on the Bench Today? The acid must remove this layer before it … These elements include lithium, potassium, calcium, sodium, magnesium, aluminum, zinc, iron and lead. b. Robert Allen has been writing professionally since 2007. Science. He has written for marketing firms, the University of Colorado's online learning department and the STP automotive blog. Copper metal react with hot and concentrated sulphuric acid but no hydrogen gas is … Like acids that are not diluted, when exploring what happens when metals react with acids, not all metals will. Metals above hydrogen on the reactivity series will react with dilute acids. Examples of metals that do react with acids include lithium, aluminium, zinc and iron. Alkaline metals, the first group in the periodic table, like lithium, sodium and potassium, will react with even cold water — breaking the H2O molecules apart to create a metallic oxide and elemental hydrogen gas. Hydrochloric acid, however, will also react with these metals — for instance, two molecules of hydrochloric acid and two atoms of metallic sodium will react to produce two molecules of sodium chloride (table salt) and one molecule of hydrogen gas. In contrast, when lead is combined with hydrochloric acid, the reaction occurs very slowly. Log in.
