Limestone is calcium carbonate and is basic in nature. When added to dilute acid, limestone will dissolve, forming the corresponding calcium salt, water and carbon dioxide.
Eg.
2HCl + CaCO3 ---> CaCl2 + H2O + CO2
or
H2SO4 + CaCO3 ---> CaSO4 + H2O + CO2
Note:
this is infact one of the major problems of acid rains. When acid rain falls on monuments made up of marbles (which is also another form of calcium carbonate), these monuments fade away as the monuments dissolve slowly.
It releases bubbles if carbon dioxide gas.
It releases bubbles if carbon dioxide gas.
when acid is on limestone to start with there would be a continues fizz. After time acid would were slowly chip and were away the rock.
Dilute hydrochloric acid (HCl) is used, and this fizzes due to the presence of calcium carbonate (CACO3) in limestone

they splash dilute acid on it. It will dissolve (very bubbly when it does)
Copper does not react with dilute Sulphuric acid.
Weathering
If you have a small sample bottle of dilute hydrochloric acid, the limestone will fizz as it is calcium carbonate and will dissolve in the acid, releasing carbon dioxide gas. The same acid will not react with the inert silica of a black chert. Sometimes chert and limestone are finely inter-bedded and the acid will pick out the limestone bands!
It releases bubbles if carbon dioxide gas.
nothing happens
When the hydrochloric acid is dropped on limestone it will start to bubble (which is carbon dioxide). After thirty minutes, there will be CaCl2 and water left on the limestone.
Sulfuric acid react with copper.
