I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction.
Reaction between marble chips and hydrochloric acid equation. 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. The old thermodynamist says. I marble chips are made from calcium carbonate hydrochloric acid calcium carbonate calcium chloride water carbon dioxideii the rate of reaction can be increased by increasing the concentration of hydrochloric acid which is the limiting factor in this equation.
δh 20c 79 9kj positive so the reactio. Hydrochloric acid is hcl. δg 20c 25 2kj negative so the reaction runs change in entropy. In words calcium carbonate reacts with hydrochloric acid to form calcium chloride water and carbon dioxide.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed. 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 cacl2 h2co3. Caco3 2hcl aq cacl2 co2 g h2 l change in free energy.
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. Marble is mostly made up of calcium carbonate which is caco3.
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. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. 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. I will use concentrations of 50cm3 using different volumes of water and acid. I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. Hcl calcium carbonate calcium chloride carbon dioxide water.
Place 40cm 3 of hydrochloric acid in an conical flask. Caco3 2hcl h2o co2 this is the reaction we will be investigating.
