Marble Chips And Nitric Acid

The marble chip is calcium carbonate caco3.

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. Again i had to ensure that this was a fair test so i kept other factors constant throughout the experiment. The results are shown below. 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. 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. Acids therefore must act on the surface of the solid marble chunks. 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. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. 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. Calcium sulfate is not very soluble in water either and accumulates as sludge at the marble acid interface inhibiting the reaction.

Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. The rate of this reaction can be changed by changing the size of the marble chips. Caco3 2hcl h2o co2 this is the reaction we will be investigating. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.

A conical flask contains the marble chips hydrochloric acid and the water that will make the reaction. 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. Marble is calcium carbonate which is not appreciably soluble in water. 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.

Aim the experiment will be on the reaction of nitric acid and marble chips. A tube to connect the conical flask to the measuring cylinder.
