Marble Chips And Nitric Acid

A tube to connect the conical flask to the measuring cylinder.

Marble chips and nitric acid. The marble chip is calcium carbonate caco3. 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. Marble chips are mostly made up of calcium carbonate which is a alkaline compound. Acids therefore must act on the surface of the solid marble chunks.

Caco3 2hcl h2o co2 this is the reaction we will be investigating. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. 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. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide.

Caco3 2hno3 ca no3 2 co2 h2o this particular reaction is rather slow and so needs to be quicker by changing the factors that affect the rate of reaction. The product of marble s reaction with sulfuric acid is calcium sulfate. Calcium sulfate is not very soluble in water either and accumulates as sludge at the marble acid interface inhibiting the reaction. Again i had to ensure that this was a fair test so i kept other factors constant throughout the experiment.

Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. 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 results are shown below. Marble is calcium carbonate which is not appreciably soluble in water.

The rate of this reaction can be changed by changing the size of the marble chips. Aim the experiment will be on the reaction of nitric acid and marble chips. 5 1247 words how the concentration of acid affects the rate of reaction pages. 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.

A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. Nitric acid and sulphuric acid for the neutralisation reactions pages.
