Hcl calcium carbonate calcium chloride carbon dioxide water.
Reaction between marble chips and hydrochloric acid equation.
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 am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is.
Hydrochloric acid is hcl.
Acids carbonates salts carbon dioxide water marble is caco3 2hcl caco3 cacl2 co2 h2o.
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.
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.
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.
δh 20c 79 9kj positive so the reactio.
I will use concentrations of 50cm3 using different volumes of water and acid.
δg 20c 25 2kj negative so the reaction runs change in entropy.
Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.
δs 20c 358 3j k change in enthalpy.
To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials.
Caco3 2hcl cacl2 h2o co2.
This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide.
Place 40cm 3 of hydrochloric acid in an conical flask.
In words calcium carbonate reacts with hydrochloric acid to form calcium chloride water and carbon dioxide.
Caco3 2hcl aq cacl2 co2 g h2 l change in free energy.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
Marble is mostly made up of calcium carbonate which is caco3.
The old thermodynamist says.
Caco3 2hcl cacl2 h2co3.
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.
H2co3 decomposes easily into h2o and co2 so the equation is.
