We are learning about chemical reactions. Today, we mixed different acids with different bases. We used test tubes to place our liquids and teaspoons to collect different acids. To mix the two different things together we used popsicle sticks and a glass beaker.
My hypothesis for citric acid and vinegar together would be for it to fizz up and foam. When we added the vinegar to the citric acid it foamed and turned yellow/brown in colour. It also smelt very bitter from the vinegar.
My hypothesis for the raro and lemon juice was for it to bubble up. What really happened was that the two dissolved. It smelt like orange juice and looked fizzy. The colour of it was very concentrated as well.
My hypothesis for tartaric acid, baking soda and vinegar was for it to fizzy, foam and bubble up. It did exactly what we thought it would. At the bottom of the beaker the baking soda and tartaric acid which wasn’t touched by the vinegar turned crystally and hard.
My hypothesis for chalk, raro and lemon juice was for it to go bubbly and hard. When we poured the acid into the base it didn’t have a very big reaction. When we mixed the two together with a popsicle stick it just dissolved and turned red in colour.

Well done Angela. I like the way you have included scientific language to write about the experiment.
