Conical flask delivery tube bung measuring cylinder x 2 water trough water stopwatch marble.
Marble chips and hydrochloric acid reaction.
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.
I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction.
Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed.
I will use concentrations of 50cm3 using different volumes of water and acid.
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.
Task my task is to measure the rate of reaction between marble chips caco 3 and hydrochloric acid 2 hcl.
To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips.
2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l.
δg 20c 25 2kj negative so the reaction runs change in entropy.
I also predict that the more dilute the acid is the more.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
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.
Marble chips experiment pilot aim.
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.
The old thermodynamist says.
Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
δh 20c 79 9kj positive so the reactio.
This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide.
I predict that the more hydrochloric acid there is the faster the chemical reaction.
Diagram plan the equipment i will be using for this experiment will be as follows.
