What happen when dilute nitric acid is added to a sample of chalk?

Chalk is calcium carbonate (CaCO3) thus addition of dilute acid will produce carbon dioxide and a calcium salt. E.g. addition of dilute hydrochloric acid will produce CO2 and calcium chloride (CaCl2).

∙ 11y agoThe predominant constituent of chalk is calcium carbonate. Therefore, carbon dioxide gas is given off, according to the equation:
CaCO3 + 2 HCl -> CaCl2 + CO2 + H2O.

What dilute acid is added to a sample of limestone the rock fizzes what chemical does the rock contain?
Dilute hydrochloric acid (HCl) is used, and this fizzes due to the presence of calcium carbonate (CACO3) in limestone

What observations can be made when dilute nitric acid is added to lead carbonate?
The lead carbonate is dissolved in nitric acid and carbon dioxide is released.

Try it on your own. (Best answer for your problem is your action)
What is the explanation for tenfold dilution technique?
In ten fold dilution we add one part of the sample into the nine part of the diluent e.g. water. It will make it ten fold dilute. If we have series of tubes to dilute then after making the ten fold dilution in first tube, take the dilute sample from the first tube in same quantity as we added sample in first tube and add it to 2nd one. then then take the same quantity from 2nd one and add to third one and so on......... from the last tube we take the adjusted quantity of dilute sample and discard it. This will make the series of ten fold dilution. If you add one part substance to 10 parts of water, you get an 11-fold dilution.
