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