Designing experiment

EqAim: Compare solid and liquid bases in neutralisation.

Hypothesis:Both bases will turn green.
Materials:
Hydrochloric Acid
Universal Indicator
Quick Eze(base)
Gaviscon(Liquid)
Beaker
Dropper
Test tube
Rack
Methods:
Measure all the testers that will be used by 3 ml(bases,acid, and indicator). Then, pour the universal indicator in the two test tubes and afterwards, the hydrochloric acid. Next, put the bases in different test tube. Repeat.

Results:
1st try. The powder doesn’t completely neutralize the acid and is more light green in color than the liquid,
2nd try. The liquid is still more green than the powder but this time the powder is greener than it is before.

Conclusion/Discussion:
We saw that liquid base is likely more to neutralize the acid than the solid. It is because the liquid dissolves faster than the powder. In our second try of experimenting, the powder tends to be more green in color than in the first try which is because we waited for a little more time for to dissolves but the liquid is still more to neutralize that acid.

Definitions:
Indigestion or ‘Heartburn’ means when the acid from the stomach is too much and it flows into the esophagus. The stomach contains cell for it to protect its walls while the esophagus doesn’t that’s why we feel pain and discomfort when we have indigestion.
