Marble chips experiment pilot aim.
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.
I also predict that the more dilute the acid is the more.
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 am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is.
I predict that the more hydrochloric acid there is the faster the chemical reaction.
The symbol equation for my investigation is image caco3 2hcl cacl2 co2 h2o.
δh 20c 79 9kj positive so the reactio.
I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed.
How can the rate of the reaction between calcium carbonate and dilute hydrochloric acid be measured.
I will use concentrations of 50cm3 using different volumes of water and acid.
I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction.
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.
Diagram plan the equipment i will be using for this experiment will be as follows.
The rate of this reaction can be measured by looking at the rate at which the product carbon dioxide gas is formed.
