Experiment - Mix carbonates and bases to acids and record the reaction that follows
Combination
|
Hypothesis
|
Reaction
|
Lemon Juice - Citric Acid
|
We predicted that the colour would change or lose it’s original colour
|
The lemon juice colour faded after being mixed into the citric acid which then after solidified.
|
Raro - Vinegar
|
We predicted that the vinegar’s colour would over power the Raro’s distinct orange colour.
|
The reaction turned the vinegar into orange coloured liquid
|
Vinegar - Tartaric Acid
|
We predicted that the vinegar would turn the tartaric acid into a black liquid like it’s original colour black.
|
It looked like coke and solidified.
|
Baking Soda - Vinegar
|
We didn’t really predict because we have done this many times.
|
It rose and foamed up due to the chemical reaction.
