The reaction using a higher concentration of hydrochloric acid is faster.
Marble chips and hydrochloric acid observations.
Compare the slopes of the two graphs.
Plot the results on the same graph.
Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area.
There are many variables that affect.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
The rate of this reaction can be changed by changing the size of the marble chips.
Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area.
Repeat the experiment with 20g of the same marble chip size and 20cm 3 of the acid made up to 40 using distilled water.
