Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
Marble chips and hydrochloric acid reaction.
δg 20c 25 2kj negative so the reaction runs change in entropy.
Conical flask delivery tube bung measuring cylinder x 2 water trough water stopwatch marble.
δs 20c 358 3j k change in enthalpy.
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.
I also predict that the more dilute the acid is the more.
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.
Diagram plan the equipment i will be using for this experiment will be as follows.
Caco3 2hcl aq cacl2 co2 g h2 l change in free energy.
The symbol equation for my investigation is image caco3 2hcl cacl2 co2 h2o.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
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.
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.
Caco3 2hcl h2o co2 this is the reaction we will be investigating.
2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l.
I will use concentrations of 50cm3 using different volumes of water and acid.
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.
