Does limestone react with acid?

Reactions with acids Since limestone is mostly calcium carbonate, it is damaged by acid rain . Sodium carbonate, magnesium carbonate, zinc carbonate and copper carbonate also react with acids – they fizz when in contact with acids, and the carbon dioxide released can be detected using limewater .

Does phyllite react with acid?

A low grade phyllite can have a certain volume of calcite and still be a phyllite as long as the major components are quartz, mica and chlorite originally derived from mudstone and siltstone. The reaction to acid (usually HCl) can be quite strong even with low percentages of calcite.

Is Dolomite acid soluble?

Dolomite and limestone are very similar rocks. They share the same color ranges of white-to-gray and white-to-light brown (although other colors such as red, green, and black are possible). They are approximately the same hardness, and they are both soluble in dilute hydrochloric acid.

What kind of acid does dolomite react with?

Dolomite produces a very weak reaction to cold, dilute hydrochloric acid; however, if the acid is warm or if the dolomite is powdered, a much stronger acid reaction will be observed. (Powdered dolomite can easily be produced by scratching it on a streak plate.)

How is the rate of dissolution of dolomite limited?

Variation of acid concentration with time for a typical run. of dolomite in HCl is limited by the rate of difrusion of acid to the solid surface, and (2) the conditions and kinetic rate expression for which the dissolution is limited by the rate at which the acid reacts at the solid surface.

How is dolomite different from limestone and dolostone?

Dolomite/dolostone reacts with acid much less vigorously than limestone; often it is necessary to scratch up the surface of the dolostone to produce a powder that will then be observed to react with the acid. Geologists use this behavioral difference as a fi eld test to discriminate between limestone and dolostone.

What kind of uses can dolomite be used for?

Dolomite’s reaction with acid also makes it useful. It is used for acid neutralization in the chemical industry, in stream restoration projects, and as a soil conditioner.
