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.
Marble chips and hydrochloric acid observations.
A demonstration of the procedure for investigating the effect of concentration on the reaction between hydrochloric acid and calcium carbonate marble chips.
The reaction using a higher concentration of hydrochloric acid is faster.
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.
There are many variables that affect.
The rate of this reaction can be changed by changing the size of the marble chips.
Compare the slopes of the two graphs.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
