Why the reaction stops quickly when sulphuric acid is added to marble chips?
When sulfuric acid is added to marble chips, a chemical reaction takes place in which the acid reacts with the calcium carbonate in the marble to produce carbon dioxide gas. This gas forms bubbles which can create a layer around the marble chips, limiting further contact with the acid and slowing down the reaction. Once the layer of gas forms, the reaction rate decreases, resulting in the rapid reaction coming to a halt.
What will happen if you put marble in hydrochloric acid?
Marble is made out of mostly carbonates. When any acid, including hydrochloric acid, is added to a carbonate, carbon dioxide will form. The acid may bubble as the reaction takes place, and some or all of the marble will be destroyed.
What gas bubbles out when drops of hydrochloric acid are dropped on marble?
Carbon dioxide gas bubbles out when drops of hydrochloric acid are dropped on marble. This reaction occurs because the hydrochloric acid reacts with the calcium carbonate in the marble, producing carbon dioxide gas as a byproduct.
What happens when an acid falls on a marble?
When an acid falls on marble, it can react with the calcium carbonate in the marble, causing it to dissolve and form bubbles of carbon dioxide gas. This reaction erodes the surface of the marble, leading to etching and loss of shine. Over time, the acid can damage and deteriorate the marble if not cleaned and neutralized promptly.
Is testing stones with acid to see if they are marble a chemical change?
No, testing stones with acid to see if they are marble is a physical change. The acid reacts with the marble to produce a fizzing or bubbling reaction, indicating the presence of calcium carbonate in the marble. This reaction does not change the fundamental chemical composition of the marble.

What two rocks are primarily composed of a mineral that bubbles with acid?
Limestone and marble are primarily composed of calcite, a mineral that reacts with acid by producing bubbles. This reaction is commonly used to identify these rocks in the field.

How long does it take for a lump of marble to produce 20ml of gas?
The time it takes for a lump of marble to produce 20ml of gas can vary depending on factors such as the size of the marble, temperature, and the reaction taking place. In a chemical reaction like the reaction between marble (calcium carbonate) and acid (such as hydrochloric acid), gas is produced. The rate of gas production can be affected by the concentration of the acid, temperature, and the surface area of the marble.

No, testing stones with acid to see if they are marble is a physical change. The acid reacts with the marble to produce a fizzing or bubbling reaction, indicating the presence of calcium carbonate in the marble. This reaction does not change the fundamental chemical composition of the marble.
What happens when marble is put into vinegar?
The carbonates in marble will react with the acid in vinegar in the reaction: acid + carbonate = water + salt + carbon dioxide. Thus, the volume of vinegar will decrease, the volume of the marble will also decrease, a salt will be produced, and effervescence occurs (bubbles are formed). To test the gas in the bubbles produced, pass it through aqueous calcium hydroxide (limewater). A white precipitate will be formed in the limewater shortly.
Does marble have gas bubbles?
Marble can contain small gas bubbles, typically trapped during the formation process when the stone was still in a molten state. These gas bubbles can give marble a speckled or cloudy appearance, adding to its unique character.
Does marble Fizz in hydrocloric acid?
Yes, marble will fizz when placed in hydrochloric acid due to a chemical reaction that releases carbon dioxide gas. This reaction between the acid and the calcium carbonate in marble causes bubbles to form, resulting in the fizzing.
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 bubbling reaction indicates that both limestone and marble contain calcium carbonate. The hydrochloric acid reacts with the calcium carbonate to produce carbon dioxide gas, which is seen as bubbles. This is a common test to identify rocks containing calcium carbonate.
Why does the metamorphic rock marble fizz with acid?
Marble fizzes with acid because it is composed of the mineral calcite (calcium carbonate - CaCO3) which reacts with acids to form the gas carbon dioxide and it is the release of the carbon dioxide gas (CO2) that causes the "fizzing" that is observed during the reaction. For example a reaction of calcium carbonate and hydrochloric acid will yield calcium chloride (CaCl2), carbon dioxide and water (H2O) as per the following reaction: CaCO3(s) + 2 HCl(aq) = CaCl2(aq) + CO2(g) + H2O(l)
