Metal Carbonate Ions

Question 1

What does metal carbonate + acid make?

Answer 1

Salt + Water + Carbon Dioxide

Question 2

What do you have to do quickly?

Answer 2

You’ll need to connect the test tube of the suspected ion to the test tube of limewater quickly so none of the CO2 escapes.

Question 3

Method?

Answer 3

We first start with the solution we are testing, to which we add some dilute acid. This will produce carbon dioxide gas.
We can then test this gas by bubbling it through a test tube with lime water. If carbonates are present the limewater
