Plot the results on the same graph.
Marble chips and hydrochloric acid observations.
Hydrochloric acid marble chips the experiment the aim of this experiment is to find out how different variables affect the rate at which the reaction between marble chips caco and hydrochloric acid hcl takes place.
Repeat the experiment with 20g of the same marble chip size and 20cm 3 of the acid made up to 40 using distilled water.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area.
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.
Compare the slopes of the two graphs.
There are many variables that affect.
