Marble Chips And Nitric Acid Experiment

Using the apparatus shown the change in mass of carbon dioxide can be measure with time.

Marble chips and nitric acid experiment. 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. To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials. The chemical equation that is going to be followed throughout the experiment will be. Place 40cm 3 of hydrochloric acid in an conical flask.

My guess is that the answer would vary depending on the concentration of the nitric acid. The experiment is repeated using smaller marble chips. All other conditions remain the same. An investigation of the reaction between marble chips and hydrochloric acid.

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. Which statement about the second experiment is correct. Acid rain contains carbonic acid nitric acid and sulphuric acid co2 no2 and so2. Conical flask glass jam jars measuring cylinder stop clock watch with seconds stop watch app direct reading balance dilute hydrochloric acid cotton wool marble chips method.

An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid. A the collisions are more frequent and higher energy. Acid rain is one of the top degradation agents for marble artefacts around the world. The rate of this reaction can be changed by changing the size of the marble chips.

This was done as the first trial showed that in the first 2 minutes the. Aim the experiment will be on the reaction of nitric acid and marble chips. One for concentrated hno3 has no2 nasty nitrogen dioxide as a product while the other for dilute hno3 has not. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.

Calcium chloride solution is also formed. Marble is especially sensitive to the degrading by acidic chemicals also to weathering. The marble chip is calcium carbonate caco3.
