Hypothesis: Our hypothesis was that when the carbonates were mixed with acid it would cause them to fizz, bubble or dissolve.

First we mixed the raro and the vinegar, there was a fizzing reaction and after the fizzing stopped the raro dissolved in the acid.

When we mixed the chalk with the vinegar it started to create a crackling noise and then began to form a thick clumpy  substance.

Third the tartaric acid was mixed with the lemon juice there was a fizzing reaction and then the tartaric acid began to dissolve.

When the tartaric acid was mixed with the vinegar the reaction was the same as when it was mixed with the lemon juice.

When the baking soda was mixed with the vinegar the mixture started to bubble and rise, then after a few seconds the mixture started to go down and dissolve.

We also noticed there was a change in the colour and smell after the carbonate was mixed with the acid.
