Does gypsum fizz in HCL?
No, gypsum does not fizz in hydrochloric acid (HCl) like carbonate minerals do. Gypsum is a sulfate mineral composed of calcium sulfate dihydrate, so it does not react with HCl to produce carbon dioxide gas like carbonates do.
What type of rock is alabaster?
Alabaster refers to varieties of two different minerals: gypsum (a hydrous sulfate of calcium) and calcite (a carbonate of calcium). Gypsum is the alabaster of the present day; calcite is generally the alabaster of the ancients
Does graphite scratch gypsum?

Which are the important raw materials required in cement industry?

How might a geologist use acid in the field to identify carbonate rocks such as anhydrite and gypsum?
If you put cold dilute Hydrochloric acid on a carbonate rock the acid dissolves the rock and you get bubbles of carbon dioxide in the acid. This reaction will only happen with carbonate rocks.
What is the difference between Chalk and Gypsum?
Chalk is a soft, white, porous sedimentary rock composed mainly of calcium carbonate. It is commonly used for writing and drawing. Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate. It is used in construction materials and as a soil conditioner.
