→Carbonate Test
#Add the [[Hydrochloric Acid]] [[solution]] to the first [[Test Tube|test tube]] containing the [[Metal Carbonate]] [[Solution]].
#Immediately attach a [[bung]] with a [[Delivery Tube|delivery tube]] to pass the [[gas]] through the [[Limewater]] in the second [[Test Tube|test tube]].
<chemmath>Na2CO3(aq) + 2HCl(aq) -> \rightarrow 2NaCl(aq) + H2O(l) + CO2(g)</chemmath>
: A [[gas]] is [[product|produced]] and bubbled through [[Limewater]].
<chemmath>CO2(g) + CaO(aq) -> \rightarrow CaCO3(s)</chemmath>
: The [[Calcium Carbonate]] makes the [[Limewater]] appear cloudy.
====Unknown Compound Test====
To identify an unknown [[Ionic Compound|ionic compound]] use each [[experiment]] mentioned above and record the [[results]] to compare with the expected [[results]] for each [[Metal Compound]].
