The higher the concentration of hydrochloric acid in the beaker the faster the reaction will take place.
Hydrochloric acid and marble chips experiment concentration.
An investigation of the reaction between marble chips and hydrochloric acid.
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.
To show that decreasing the concentration of the.
I will keep the mass of marble chips the same in each experiment and i will use medium sized marble chips so that the surface area does not affect the.
Place 40cm 3 of hydrochloric acid in an conical flask.
Conical flask glass jam jars measuring cylinder stop clock watch with seconds stop watch app direct reading balance dilute hydrochloric acid cotton wool marble chips method.
I am going to see if changing the concentration of acid affects the speed at which it reacts with marble chips.
Repeat experiment with different size marble chips.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
Marble chips hydrochloric acid carbon dioxide water calcium chloride.
Calcium chloride solution is also formed.
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.
There are many variables that affect.
This is because there will be more hydrochloric acid particles to collide with the marble chip particles.
Therefore resulting in a quicker reaction.
Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.
