Task my task is to measure the rate of reaction between marble chips caco 3 and hydrochloric acid 2 hcl.
Marble chips and hydrochloric acid reaction.
I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed.
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.
δs 20c 358 3j k change in enthalpy.
Caco3 2hcl aq cacl2 co2 g h2 l change in free energy.
I predict that the more hydrochloric acid there is the faster the chemical reaction.
I also predict that the more dilute the acid is the more.
Marble chips experiment pilot aim.
Caco3 2hcl h2o co2 this is the reaction we will be investigating.
δg 20c 25 2kj negative so the reaction runs change in entropy.
Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips.
δh 20c 79 9kj positive so the reactio.
I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is.
In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
Diagram plan the equipment i will be using for this experiment will be as follows.
I will use concentrations of 50cm3 using different volumes of water and acid.
The symbol equation for my investigation is image caco3 2hcl cacl2 co2 h2o.
This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide.
I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction.
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.
2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
The old thermodynamist says.
