Marble Chips And Hydrochloric Acid Reaction

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.

Marble chips and hydrochloric acid reaction.

2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l. I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is. How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured. The symbol equation for my investigation is image caco3 2hcl cacl2 co2 h2o.

δh 20c 79 9kj positive so the reactio. The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed. I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation calcium hydrochloric calcium carbon water image carbonate acid chloride dioxide.

Hcl calcium carbonate calcium chloride carbon dioxide water. δg 20c 25 2kj negative so the reaction runs change in entropy. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. I will use concentrations of 50cm3 using different volumes of water and acid.

The old thermodynamist says. Caco3 2hcl aq cacl2 co2 g h2 l change in free energy. Conical flask delivery tube bung measuring cylinder x 2 water trough water stopwatch marble. δs 20c 358 3j k change in enthalpy.

A chemistry investigation to look at the rates of reaction between marble chips and hydrochloric acid. 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 experiment pilot aim.

Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. I predict that the more hydrochloric acid there is the faster the chemical reaction. To investigate how the concentration of hydrochloric acid affect the speed of reaction with marble chips. 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.

Caco3 2hcl h2o co2 this is the reaction we will be investigating. Task my task is to measure the rate of reaction between marble chips caco 3 and hydrochloric acid 2 hcl.
