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