Single+Replacement+II


 * Station 1 **

Single Replacement is when one element in a compound is replaced by a more active element to make a new compound. A real life example is: Mg(s) + 2HCl -->MgCl 2(aq) + H2(g) In this example magnesium is replacing the hydrogen in hydrochloric acid to produce magnesium chloride and hydrogen because magnesium is more active than hydrogen. In simpler form: X + AB --> AX + B Another real life example is: Cl2 + 2NaBr à  Br2 + 2NaCl In this example chlorine is replacing bromine in sodium bromide to create sodium chloride.
