Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area.
Marble chips and hydrochloric acid observations.
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.
Plot the results on the same graph.
Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area.
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.
The reaction using a higher concentration of hydrochloric acid is faster.
A demonstration of the procedure for investigating the effect of concentration on the reaction between hydrochloric acid and calcium carbonate marble chips.
