Some acids that react with metals are sulfuric acid, hydrochloric acid and nitric acid. The most common metals that react with acids are iron, lead, magnesium and zinc.
Many metals react with acids, but not all. As metals react with acids, salts and hydrogen gas form.
Aluminium, iron, lead, magnesium, tin and zinc all react safely with diluted acid. Magnesium has the fastest reaction and lead has the slowest.
Zinc is often combined with diluted sulphuric acid in creating laboratory prepared hydrogen. The reaction between them is slow at room temperature, but the rate can be increased by adding a small amount of copper sulphate. The zinc displaces the copper, which then acts as a catalyst.
Metals that react with acids are called active metals. These metals can displace the hydrogen ions from acids to create hydrogen gas. Copper, gold, platinum and silver are not active enough to react with acids. They cannot displace hydrogen from non-metal anions.
The general equation for this form of chemical reaction is written as "active metal + acid = salt + hydrogen gas." Hydrochloric acid creates a metal chloride and sulphuric acid creates a metal sulphate.
With nitric acid, the nitrate is formed but the gas produced is rarely hydrogen. More often, it is an oxide of nitrogen.Learn More
Some common examples of acids are hydrosulfuric acid, hydrobromic acid, hydrochloric acid, hydroiodic and hydrofluoric acid, while some common bases are calcium hydroxide, sodium hydroxide, barium hydroxide, ammonium hydroxide, magnesium hydroxide and potassium hydroxide. The acidity or basicity of a substance is measured on the pH scale. Acids increase the concentration of hydronium ions when dissolved in water, whereas bases decrease it.Full Answer >
Metal oxides are not acidic. Most metal oxides are basic, and a few demonstrate traits of both acidic and basic compounds. Acidic oxides are formed by non-metals.Full Answer >
The formulas of some monoprotic acids are HCl, HNO3, CH3CO2H and C6H5CO2H. Their names are hydrochloric acid, nitric acid, acetic acid and benzoic acid respectively.Full Answer >
Pure rayon shrinks when washed or dried if it has not been pretreated when manufactured. Rayon is a delicate fabric that was originally designed as a dry clean only material. Blended rayon with a 30 percent or more ratio of polyester is normally safe in the washer or dryer.Full Answer >
