Compare the slopes of the two graphs.
Marble chips and hydrochloric acid observations.
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.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung.
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.
Plot the results on the same graph.
There are many variables that affect.
The rate of this reaction can be changed by changing the size of the marble chips.
