Different acid levels we are using:
0.1
0.5
1.0
1.5
2.0
In the experiment, we will use different concentrations of hydrochloric acid to see what effect it has on pieces of limestone.
- What you think will happen - Hypothesis
- Why it is happening?
- I think the acid will make a big hole in the limestone
So with 0.1, that barely did anything to the limestone and marble, it just fizzed up a bit. With 0.5, it also didn't really do much but it fizzed up a tiny bit more than 0.1. However, 1.0 was much better than the other 2, it fizzed up quite a bit and put a little hole in the limestone and it was more effective with the marble. 1.5 did slightly better like how it put in a slightly bigger hole and fizzed up more. 2.0 was the strongest we had, it fizzed up the whole limestone and put a decent hole in it but we couldn't do any higher than 2.0 otherwise it would be a bit too dangerous to use.
Hi Kaiden, Good job! You guys chose to do something really different and interesting. Next time, it would be great to see an explanation of why the limestone and marble reacted with the hydrochloric acid.
