Carbonate minerals generally display a fizzing or bubble producing reaction with acids.

you need to determine; hardness, color, transparency, and how they break. Those 4 combined will identify most minerals. There are other tests, but they get more complicated.
Hardness test for minerals
It distinguishes calciferous minerals from other minerals.
streak test, hardness test, scratch test, color test
The purpose is to discover how the rocks and minerals were formed and what the rocks and minerals are made of.
These are all properties of minerals, and barium is an element which does not occur in a pure (native) form in the earth. Different minerals with barium as a constituent have various different properties.
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.
