Which statement about the second experiment is correct.
Marble chips and nitric acid experiment.
This was done as the first trial showed that in the first 2 minutes the.
The marble chip is calcium carbonate caco3.
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.
One for concentrated hno3 has no2 nasty nitrogen dioxide as a product while the other for dilute hno3 has not.
15 in an experiment nitric acid is added to excess marble chips and the volume of carbon dioxide formed is measured.
Marble is especially sensitive to the degrading by acidic chemicals also to weathering.
The rate of this reaction can be changed by changing the size of the marble chips.
An outline of an experiment that could be used to find the time and hence rate of reaction of marble chips and hydrochloric acid.
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.
Using the apparatus shown the change in mass of carbon dioxide can be measure with time.
My guess is that the answer would vary depending on the concentration of the nitric acid.
Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas.
All other conditions remain the same.
Acid rain is one of the top degradation agents for marble artefacts around the world.
An investigation of the reaction between marble chips and hydrochloric acid.
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.
To investigate the effect of concentration on the reaction between marble chips and hydrochloric acid materials.
A the collisions are more frequent and higher energy.
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.
The chemical equation that is going to be followed throughout the experiment will be.
Place 40cm 3 of hydrochloric acid in an conical flask.
Calcium chloride solution is also formed.
Aim the experiment will be on the reaction of nitric acid and marble chips.
