WALHT: Observe and report on the chemical reaction that occur when combining substances together.

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.
