Lesson outcome
I can write balanced equations for acid – metal reactions, as well as acid - metal carbonate reactions, and predict the names and states of products.
Show transcript
metal + acid ⭢ salt + hydrogen; metal carbonate + acid → salt + water + carbon dioxide
The test for hydrogen gas is to introduce a lighted splint, which will make a squeaky pop in hydrogen.
The name of a salt formed is dependent on the acid used.
(s), (l), (g), (aq) in chemical equations identify the state of substances as solid, liquid, gas or in aqueous solution.
Carbon dioxide can be bubbled through limewater, which turns cloudy (test for CO₂).
