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.
Acid tests are usually performed by taking very dilute HCl (HydroChloric) acid and then pouring some onto the mineral being tested. If the mineral bubbles and releases carbon dioxide, (or not,) that will help you to identify the mineral.
I hope my answer was helpful.
A common acid test can be done using cool, dilute hydrochloric acid (HCl). All "carbonate minerals" (those whose chemical composition includes carbonate) fizz when HCl is applied to them. Some minerals which react with HCl include calcite and dolomite.
It distinguishes calciferous minerals from other minerals.
Calcite is the easiest to identify!

Because some minerals dont have a streak, or may share a streak colour with another mineral.
You identify minerals through a streak test. This involves taking the tile and the mineral to be identified and rubbing them together. This produces a colored streak on the tile, which can be used to identify the mineral. Consult a field guide for specific colors.
what is the most reliable way to identify a mineral?
Because some minerals have the same color streak, don't have a streak, or the streak is hard to see

A streak test is used to determine a minerals streak color. This can help in the identification of minerals.
Mineralogists often use the physical properties of minerals to identify them. The most reliable test in order to identify a mineral is the test for hardness.

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.
Some minerals give off carbon dioxide bubble when acid is dropped on them. Geologists have termed this as the "acid test".
Yes, you can usually identify the mineral salt by its taste. However, with most minerals one would apply a series of tests, eg hardness, flame test, colour, density, streak, shape in order to identify the mineral.
Pouring hydrochloric acid, or HCL, over a mineral will cause carbonate minerals to effervesce. This application is called the "acid test," it simply examines the mineral or rocks reaction to acid. Calcite is the most commonly found carbonate mineral and it will fizz during the acid test. Dolomite is another carbonate mineral; however, it will only fizz if it is first powdered. Experiments also show that undiluted vinegar can cause effervescing, but it produces less vivacious results. Some sedimentary rocks that fizz include chalk, coquina, oolic limestone, fossilferous limestone, and micrite. The metamorphic rock marble also fizzes.
The scratch test, use a series of mineral with known hardness and scratch the mineral. From softest to hardest, and note where a scratch is made. You can also look for distinctive physical characteristics.
