When acids react with metals, they produce a salt and hydrogen gas. Most metals react with acids, but not all. The general equation that describes the chemical reaction between an acid and metal is metal + acid = salt + hydrogen gas.Know More
This type of chemical reaction is known as a single displacement reaction, where an element displaces another in a compound. The hydrogen in acids is displaced by the metals to produce hydrogen gas.
The two common acids are sulfuric acid (H2SO4) and hydrochloric acid (HCl). The most active metals are magnesium (Mg), zinc (Zn), iron (Fe) and lead (Pb). The most inactive metals are copper (Cu), silver (Ag) and gold (Au).
Active metals can displace hydrogen ions from acids, while inactive metals cannot. The salt produced when an acid reacts with a metal differs, in that the type of salt produced depends on the type of acid used for the reaction. Sulfuric acid produces sulfate salts, while hydrochloric acid produces chloride salts.
Here are some examples of acid metal chemical reactions:
Metals are shiny because metals contain free electrons that vibrate when they come in contact with light. When the electrons vibrate, they produce their own light. This is reflected back and is what creates the shiny, lustrous appearance of metal.Full Answer >
The Haber process is a chemical reaction in which diatomic nitrogen gas reacts with hydrogen gas to form ammonia. The reaction equation is: N2 + 3H2 --> 2NH3. Although this reaction looks deceptively simple, the Haber process generates ammonia only under conditions of high pressure and temperature, on the order of 200 atmospheres and 400 degrees Celsius. Iron oxides or osmium can act as catalysts to speed up the reaction.Full Answer >
Compounds of silicon and hydrogen, known as silanes, react explosively with oxygen and react with water, forming silicon dioxide and water and silicon dioxide and hydrogen gas respectively. Silicon accounts for 28 percent of the earth's crust but it does not appear naturally in its elemental form.Full Answer >
Uncoated lithium metal reacts with water to form a colorless lithium hydroxide solution and hydrogen gas. The resulting solution is basic because of the resulting hydroxide ions. The reaction is both spontaneous and exothermic, but the amount of heat produced is lower than other metals in group 1A.Full Answer >
