Marble Chips And Nitric Acid

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.

Marble chips and nitric acid.

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 is calcium carbonate which is not appreciably soluble in water. Again i had to ensure that this was a fair test so i kept other factors constant throughout the experiment. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.

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. The product of marble s reaction with sulfuric acid is calcium sulfate. 5 1247 words how the concentration of acid affects the rate of reaction pages. Caco3 2hcl h2o co2 this is the reaction we will be investigating.

An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. One for concentrated hno3 has no2 nasty nitrogen dioxide as a product while the other for dilute hno3 has not as nasty nitrogen monoxide no as a product. The reason i think it would vary is that you get different reactions when one puts pure copper in either concentrated or dilute nitric acid.

I used 20cm3 of 2 molar nitric acid and 2 grams of marble chips and then i monitored the change in weight for 4 minutes. Calcium sulfate is not very soluble in water either and accumulates as sludge at the marble acid interface inhibiting the reaction. Nitric acid and sulphuric acid for the neutralisation reactions pages. The rate of this reaction can be changed by changing the size of the marble chips.

The marble chip is calcium carbonate caco3. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. Acids therefore must act on the surface of the solid marble chunks. A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction.

A tube to connect the conical flask to the measuring cylinder. I am testing small marble chips large marble chips and medium marble chips.
