Which common minerals fizzes when dilute hydrochloric acid HCI is placed on it?
Calcite, Limestone, Chalk, Marble. They are all geological forms of calcium carbonate.
What could happen if gold is placed in dilute hydrochloric acid?
Nothing, gold does not react with hydrochloric acid, if there are impurities of other metals in gold then impurities may react and form chloride salts.
What simple chemical test will distinguish chalk from white claystone?
Items made from Calcium Carbonate will fizz when a solution of dilute hydrochloric acid is placed on them. Ceramic items will not fizz when a solution of dilute hydrochloric acid is placed on them.
A piece of iron is placed in hydrochloric acid what are the products?
When a piece of iron is placed in hydrochloric acid, the products are Iron (II) chloride and hydrogen gas.
What happens when water and chalk mix?
When a drop of dilute hydrochloric acid is placed on a piece of Chalk, the acid reacts with the calcite and forms bubbles of carbon dioxide. This "fizz" reaction is so characteristic of limestone than many geologists carry a small bottle of dilute hydrochloric acid into the field for a rapid and easy identification of limestone. During the reaction, the bubbles of carbon dioxide rise, then turn a brownish color, and then decrease in size. This is weird because the hydrochloric acid starts out as a white fizz.

How can you check if a rock is calcite?
Calcite reacts to acid. The best thing to do to determine if a mineral is calcite is to place a drop of dilute hydrochloric acid on a sample. If the mineral fizzes and carbon dioxide bubbles are produced, the mineral is calcite. Place a drop of dilute hydrochloric acid on the mineral. If it fizzes and carbon dioxide bubbles are produced, the mineral is calcite.
What could happen if gold is placed in dilute hydrochloric acid?
Nothing, gold does not react with hydrochloric acid, if there are impurities of other metals in gold then impurities may react and form chloride salts.
When dilute hydrochloric acid is placed on the sedimentary rock limestone and the metamorphic rock marble bubbling reaction occurs with both What would this indicate?
The minerals of these rocks are similar.
How is a mineral acid test used to identify minerals?
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.

Both calcite and quartz can be found as clear crystals what tests can be used to correctly identify them?
Quartz would scratch the calcite. Calcite would not scratch the quartz. Calcite will react with dilute hydrochloric acid. Quartz will not. Calcite will exhibit double refraction. Quartz will not. If the crystal forms are intact, quartz crystal may appear six sided with pyramidal terminations. If they are of equal size, the quartz will be heavier.
What happens when hydrochloric acid is placed on calcite?
It effervesces vigorously. [effervesces means to fizz or bubble] It reacts with strong acids, releasing carbon dioxide: CaCO3(s) + 2 HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l)
What will fizz when placed on a calcite mineral?
Acid will fizz when placed on a calcite mineral
What substance will fizz when placed on a calcite mineral?
Calcite, which is the compound calcium carbonate (CaCO3) forms carbonic acid (H2CO3) which decomposes into water and carbon dioxide gas. Here is the two step reaction with hydrochloric acid: 2HCl + CaCO3 --> CaCl2 + H2CO3 H2CO3 --> CO2 + H2O
A piece of iron is placed in hydrochloric acid what are the products?
When a piece of iron is placed in hydrochloric acid, the products are Iron (II) chloride and hydrogen gas.
What does hydrochloric acid always gives?
Hydrochloric acid, HCl, always gives an H+ ion when placed in solution. Hence it is an acid.
