When calcium carbonate and hydrochloric acid react bubbles form. How do you know a reaction occurred?
You can tell that a reaction occurred because you observed the formation of bubbles, which indicates the release of a gas (carbon dioxide) as a product of the reaction between calcium carbonate and hydrochloric acid. The appearance of bubbles is a clear sign of a chemical change taking place.
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.
When carbonate minerals come in contact with hydrochloric acid they?
When carbonate minerals come in contact with hydrochloric acid, they effervesce (produce bubbles) due to the release of carbon dioxide gas. This reaction indicates the presence of carbonate ions in the mineral. The carbon dioxide bubbles are evidence of a chemical reaction taking place between the carbonate mineral and the hydrochloric acid.
Which carbonate mineral reacts readily with cool dilute hydrochloric acid to produce visible bubbles of carbon dioxide gas?
Any carbonate will fizz. Examples would be calcite, marble, limestone. They are all calcium carbonate.
What happens when you mix copper carbonate with hydrochloric acid?
When copper carbonate is mixed with hydrochloric acid, a chemical reaction occurs which produces copper chloride, carbon dioxide gas, and water. The copper carbonate will dissolve and react with the hydrochloric acid to form a blue-green solution. The carbon dioxide gas bubbles out of the solution, creating fizzing or effervescence.

Why does the vinegar eat the eggshell?
Because the acetic acid in the vinegar reacts with the solid calcium carbonate crystals that make up the eggshell, separating them into their calcium and carbonate parts, the calcium ions floats free and the carbonate makes the bubbles (carbon dioxide) that you can see on the egg. The protein that binds the calcium and carbonate is the froth that you can see on the top.

How does vinigar make an eggshell soft?
Vinegar is an acid that reacts with the calcium carbonate in the eggshell, causing it to break down and dissolve. This process creates bubbles of carbon dioxide gas, which weakens the structure of the eggshell and makes it soft.
What happens when you mix copper carbonate with hydrochloric acid?

The copper carbonate will dissolve and react with the hydrochloric acid to form a blue-green solution. The carbon dioxide gas bubbles out of the solution, creating fizzing or effervescence.
What is the procedure for making and isolating sodium chloride from sodium carbonate?
put the mixture in water and add hydrochloric acid the carbonate becomes decomposed when no further bubbles appear by adding hydrochloric acid then heat the mixture till dryness and get the solid sodium chloride.
Calcium carbonate hydrochloric acid what?
When calcium carbonate reacts with hydrochloric acid, it produces calcium chloride, water, and carbon dioxide gas. This reaction is commonly used to test for the presence of carbonates in a substance, as the carbon dioxide gas is given off as bubbles.
How can you tell if the reaction of calcium carbonate and hydrochloric acid is finished?
You can tell if the reaction is finished when there are no more bubbles of gas being produced. This indicates that all the calcium carbonate has reacted with the hydrochloric acid. You can also test by adding a few more drops of hydrochloric acid to see if any additional bubbles are produced.
What does acid test tell us about a mineral?
The acid test helps determine if a mineral is a carbonate by observing if it produces bubbles when an acid, usually hydrochloric acid, is applied to it. If the mineral fizzes and produces bubbles, it indicates the presence of carbonate minerals such as calcite or dolomite.
What happens if egg is put to Hcl and then water?
The egg in HCl reacts violently as the calcium carbonate on the outer surface of egg is dissolved. This is what actually happens : The egg in the hydrochloric acid is lighter, because the gas bubbles provide a floatation device, than the acid so it stayed at the top. The bubbles occurred because the calcium carbonate on the egg shell reacted with the acid. Carbon dioxide bubbles are produced, causing the egg to rotate and spin. The carbon dioxide bubbles on top of the eggs break. In the meantime more bubbles are attached to the bottom of the egg. These bubbles now cause the egg to spin and repeat the process. The bubbles attached to the egg also made it less dense. After this experiment, the egg will not have a shell. It will have dissolved. then when you place this egg in water, Osmosis takes place. Well, the egg is 90% water. So now when you keep the egg in water it kind of pushes the egg membrane. Basically, water is flowing into the egg and the egg swells as the water enters it.
