Marble Chips And Nitric Acid Experiment

Acid rain is one of the top degradation agents for marble artefacts around the world.

Marble chips and nitric acid experiment.

Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. 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. This was done as the first trial showed that in the first 2 minutes the. Which statement about the second experiment is correct.

A the collisions are more frequent and higher energy. 15 in an experiment nitric acid is added to excess marble chips and the volume of carbon dioxide formed is measured. Aim the experiment will be on the reaction of nitric acid and marble chips. 3m hydrochloric acid with large marble chips 1 5m hydrochloric acid with small marble chips 3m hydrochloric acid with small marble chips a reading was taken initially every 15 seconds for a minute and then every 30 seconds for the next 4 minutes.

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 rate of this reaction can be changed by changing the size of the marble chips. The marble chip is calcium carbonate caco3. My guess is that the answer would vary depending on the concentration of the nitric acid.

An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid. Acid rain contains carbonic acid nitric acid and sulphuric acid co2 no2 and so2. The chemical equation that is going to be followed throughout the experiment will be. Using the apparatus shown the change in mass of carbon dioxide can be measure with time.

Place 40cm 3 of hydrochloric acid in an conical flask. Marble is especially sensitive to the degrading by acidic chemicals also to weathering. An investigation of the reaction between marble chips and hydrochloric acid. The experiment is repeated using smaller marble chips.

All other conditions remain the same. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. Calcium chloride solution is also formed.
