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.Continue Reading
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 about Acids & Bases
A list of acids and their sources includes hydrochloric acid, which is produced naturally in the stomach to help the body break down and digest food, and citric acid, which is naturally found in citrus fruits. While hydrochloric acid is considered a strong acid, citric acid is considered weak enough for humans to safely ingest. Industries use citric acid to preserve and pickle foods.Full Answer >
Carbonic acid, hydrochloric acid and acetic acid are some acids that react with limestone, causing it to dissolve. Each of these acids reacts with limestone in different ways. Limestone is made up mainly of calcite that is the chemical compound calcium carbonate.Full Answer >
Some of the properties of acids are that they conduct electricity when they are dissolved in water, liberate hydrogen when they react with active metals and, when combined with a base, will produce a salt and a neutralized base. Acids also have a pH which is less than 7 in an aqueous solution, and will change the color of blue litmus paper to red. In an operational sense, acids increase the concentration of H+ ions when they are dissolved in water.Full Answer >
Examples of acids include vinegar, citrus fruits, tomato juice, black coffee, bananas, milk, sulfuric acid, battery acid and hydrochloric acid, which is a digestive compound found in the stomach. Acids are ionic compounds made up of positively and negatively charged ions that separate in water to form hydrogen ions.Full Answer >
