Yes
Yes, Copper oxide does fizz when it reacts with Sulphuric Acid
A drop of acid will make it fizz.
is soluble in water and will fizz when hydrochloric acid is added
Fizz
Hydrochloric acid is used by geologists in the field to test if a rock is a carbonate and to ...
Minerals such as calcite, dolomite, and limestone will fizz when hydrochloric acid is dropped on them. This fizzing occurs due to the reaction between the acid and the carbonate minerals, producing carbon dioxide gas.
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!
Dilute hydrochloric acid reacts with limestone to form calcium chloride, carbon dioxide, and water. This reaction causes the limestone to break down and dissolve, resulting in the release of gas bubbles and the formation of a calcium chloride solution.
Minerals that typically fizz when in contact with hydrochloric acid include calcite, dolomite, and limestone. This fizzing occurs because these minerals contain calcium carbonate, which reacts with the acid to produce carbon dioxide gas.
Statues made of limestone or marble may fizz in acid rain due to the chemical reaction between the calcium carbonate in the stone and the acid. This reaction forms carbon dioxide gas, which results in the fizzing or bubbling when the acid comes into contact with the statue.
The sedimentary rock that forms calcium carbonate and fizzes in acid is likely limestone. Limestone is a common sedimentary rock primarily composed of calcite, a form of calcium carbonate. When exposed to acids such as vinegar or hydrochloric acid, limestone will fizz or effervesce due to the release of carbon dioxide gas.
One common chemical test to identify limestone is the acid test. Limestone will react with hydrochloric acid to produce bubbles of carbon dioxide gas. Another test involves applying a drop of dilute hydrochloric acid to the surface of the rock; if it fizzes, then it likely contains calcium carbonate, the main component of limestone.
