Dilute acid or vinegar is placed on the specimen to see if it effervesces or reacts. If it instantly reacts it is probably a carbonate mineral like calcite. Other minerals may slowly dissove in the acid. Some minerals have no reaction to the acid.
Geologists use the acid test to identify and distinguish between different types of minerals based on their reaction to acid. By observing if a mineral fizzes or dissolves when exposed to acid, geologists can determine the mineral's chemical composition.
If the acid test is positive for a mineral, the surface of the mineral may show signs of fizzing or bubbling due to a chemical reaction between the acid and the mineral. This reaction indicates that the mineral contains carbonate minerals like calcite or dolomite, which are reactive to acid.
The streak test is used to identify minerals by rubbing the mineral against an unglazed porcelain plate to observe the color of the powder left behind. This color can sometimes be different from the outward color of the mineral and is helpful in distinguishing between similar-looking minerals.
Mineralogists use various tests to identify minerals, including the Mohs hardness scale, streak test, color, luster, cleavage, and specific gravity. These tests can help in determining the physical and chemical properties of a mineral, which are then compared to known mineral data to make an identification.
The streak test involves studying the color of the powdered form of a mineral. This is typically done by rubbing the mineral against an unglazed porcelain tile to see the color of the streak left behind. This test can help identify minerals with different colors in their powdered form compared to their natural form.
The acid test is used to determine if a mineral contains carbonate minerals. When a mineral fizzes or reacts with acid, it indicates the presence of carbonate minerals such as calcite or dolomite. This test helps mineralogists identify and distinguish between different minerals.

It distinguishes calciferous minerals from other minerals.
The acid test is used to determine the presence of carbonate minerals in a sample. If the mineral fizzes or reacts with acid, it indicates the presence of carbonate minerals such as calcite or dolomite.
Minerals that contain carbonate minerals, such as calcite or dolomite, will bubble when treated with hydrochloric acid due to the release of carbon dioxide gas from the reaction between the acid and the carbonate minerals. This bubbling effect is a simple test to identify carbonate minerals in mineral samples.
If the acid test is positive for a mineral, the surface of the mineral may show signs of fizzing or bubbling due to a chemical reaction between the acid and the mineral. This reaction indicates that the mineral contains carbonate minerals like calcite or dolomite, which are reactive to acid.
The acid test helps determine if a mineral is a carbonate by observing if it produces bubbles when an acid, usually hydrochloric acid, is applied to it. If the mineral fizzes and produces bubbles, it indicates the presence of carbonate minerals such as calcite or dolomite.
Calcite is a mineral that can be broken down by acid, particularly by dilute hydrochloric acid. The acid reacts with the calcium carbonate in calcite, causing it to dissolve and release carbon dioxide gas. This reaction is commonly used to test and identify certain minerals in geology.
Calcite is a mineral that reacts with acid, specifically hydrochloric acid, only when it is scratched. This test is known as the "acid test" and is commonly used in mineral identification. When calcite is scratched, fresh surfaces are exposed, allowing the acid to react with the mineral.
The streak test is used to identify minerals by rubbing the mineral against an unglazed porcelain plate to observe the color of the powder left behind. This color can sometimes be different from the outward color of the mineral and is helpful in distinguishing between similar-looking minerals.
A streak test is used to determine a minerals streak color. This can help in with the identification of minerals. A streak test is performed by rubbing the mineral on an unglazed ceraminc tile, then observing the color of the streak which is left behind. All minerals do not leave streaks. Harder minerals will not streak, but this can also be used as a tool for identifying the mineral, if you are familiar with the hardness scale.
