Frazer is Chemistry: A7 Salts

Friday, September 2, 2011

Name the salts formed by reacting metals, metal oxides and metal carbonates with HCl, H₂SO₄ and HNO₃

A chemical reaction happens if you mix together an acid and a base.

$Metal\, oxide\: +\: Acid\: \rightarrow a\, Salt\: +\: Water$

The equation of the salt is given by the metal from the metal oxide and the chemicals in the acid, minus the Hydrogen:

$MgO_{(s)}\: +\: 2HCl_{(aq)}\: \rightarrow \: MgCl_{(aq)}\: +\: H_{2}O_{(l)}$

$Magnesium\, oxide\: +\: Hydrochloric\, acid\: \rightarrow Magnesium\, Chloride\: +\: Water$

When mixing a carbonate with an acid an extra element is formed, this is Carbon Dioxide (CO₂)

$Metal\, Carbonate +\: Acid\: \rightarrow a\, Salt\: +\: Water\: +\: Carbon\, Dioxide$
