Marble is mostly made up of calcium carbonate which is caco3.
Reaction between marble chips and hydrochloric acid equation.
Acids carbonates salts carbon dioxide water marble is caco3 2hcl caco3 cacl2 co2 h2o.
I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
Place 40cm 3 of hydrochloric acid in an conical flask.
δg 20c 25 2kj negative so the reaction runs change in entropy.
Conical flask glass jam jars measuring cylinder stop clock watch with seconds stop watch app direct reading balance dilute hydrochloric acid cotton wool marble chips method.
2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l.
Caco3 2hcl aq cacl2 co2 g h2 l change in free energy.
δh 20c 79 9kj positive so the reactio.
I will use concentrations of 50cm3 using different volumes of water and acid.
Hcl calcium carbonate calcium chloride carbon dioxide water.
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.
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 marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
Caco3 2hcl cacl2 h2o co2.
δs 20c 358 3j k change in enthalpy.
I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed.
Caco3 2hcl h2o co2 this is the reaction we will be investigating.
H2co3 decomposes easily into h2o and co2 so the equation is.
This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide.
To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials.
Caco3 2hcl cacl2 h2co3.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
Marble chips are mostly made up of calcium carbonate which is a alkaline compound.
The symbol equation for my investigation is image caco3 2hcl cacl2 co2 h2o.
