Marble chips experiment pilot aim.
Marble chips and hydrochloric acid reaction.
The symbol equation for my investigation is image caco3 2hcl cacl2 co2 h2o.
An investigation into how changing one variable influences the rate of reaction between marble chips and dilute hydrochloric acid planning section when dilute hydrochloric acid reacts with marble chips the following reactions occurs.
I will use concentrations of 50cm3 using different volumes of water and acid.
δh 20c 79 9kj positive so the reactio.
I predict that the more hydrochloric acid there is the faster the chemical reaction.
To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips.
Caco3 2hcl aq cacl2 co2 g h2 l change in free energy.
I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is.
A chemistry investigation to look at the rates of reaction between marble chips and hydrochloric acid.
Conical flask delivery tube bung measuring cylinder x 2 water trough water stopwatch marble.
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.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
Diagram plan the equipment i will be using for this experiment will be as follows.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
Caco3 2hcl h2o co2 this is the reaction we will be investigating.
I also predict that the more dilute the acid is the more.
δg 20c 25 2kj negative so the reaction runs change in entropy.
I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction.
