Transcript of Vinegar Chalk Experiment

Vinegar and chalk Experiment
Experimental Design
EQ:
What happens to chalk in water versus acid (Vinegar)?
Independent:
The liquid it's put in.
Dependent:
Reaction on chalk.
Control:
Water, same materials.
Hypothesis:
If the chalk is put in a liquid higher in acidity, then the chalk will dissolve more.
Data/Observations
Water:
Nothing really happened,

Vinegar:
The reaction was faster. There were lots of bubbles. It was dissolving pretty quickly
Results
Vinegar:
The chalk dissolved

Water:
The chalk didn't do anything
Conclusion Question
1)

Q)
What were some signs that weathering was occurring?
A)
Some signs that weathering was occurring are the bubbles, the solution became cloudy, and the chalk started dissolving.
Conclusion Question
2)

Q)
Was your hypothesis supported
by the data?
A)
The hypothesis was; If the chalk is tested in a liquid with high acidity, then the chalk will dissolve more. The chalk in the vinegar dissolved more because the vinegar has more acid in it, so it broke down the chalk more than the water did.
Conclusion Question
3) Q) C:
Which substance, water or acid (vinegar) weathered the substance more quickly?
A)
The acid (vinegar) weathered the substance more quickly. The water had no effect on the chalk, but the vinegar dissolved the chalk.
Conclusion Question
4) Q)
How could the experiment be improved?
A)
The chalk could be timed for a certain amount of time in each substance to see which one dissolves more.
