What happens when you put limestone in water?
What happens when you put limestone in water?
Limestone (CaCO3) reacts with hydrogen ions in water. These are always present in water, since water undergoes autoprotolysis: H2O(l) = H+(aq) + OH-(aq) The more acidic the water is, the more limestone will react, and erode.
Can limestone withstand water?
Limestone is extremely durable. It does, however, absorb water and, since it is a carbonate rock, it is highly reactive when exposed to acids or even mildly acidic rain water, and it can suffer substantial deterioration.
Does limestone have bubbles?
Rocks that contain calcium carbonate can erode when they encounter acids, and limestone contains calcium carbonate. As the acid starts to dissolve the calcium carbonate, we can see the release of carbon dioxide bubbles that fizz upward.
Does limestone melt in water?
Limestone is mostly made up of the mineral calcium carbonate (CaCO3). But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve.
Does limestone fizz in acid?
Limestone is an unusual rock in that it fizzes when dilute acid is placed on its surface. When dilute acid is placed on a sample of limestone rock, it fizzes. The calcium carbonate present in the limestone is reacting with the acid to produce carbon dioxide gas.
How hard is the limestone?
Although relatively soft, with a Mohs hardness of 2 to 4, dense limestone can have a crushing strength of up to 180 MPa. For comparison, concrete typically has a crushing strength of about 40 MPa.
Does vinegar ruin limestone?
Some stones such as marble, travertine, or limestone react adversely with vinegar because it is acidic.” “They will etch or burn the surface of your stone.” While some chemicals may not noticeably damage durable stones such as granite, they can break down any sealers that have been applied to the stone.
What will dissolve limestone?
Vinegar, an acid, dissolves bits of a material called calcium carbonate in the limestone.
Why does limestone fizz with acid?
Limestone is an unusual rock in that it fizzes when dilute acid is placed on its surface. It is the presence of calcium carbonate that is responsible for this. The calcium carbonate present in the limestone is reacting with the acid to produce carbon dioxide gas.
What does vinegar do to limestone?
Vinegar, an acid, dissolves bits of a material called calcium carbonate in the limestone. This releases carbon dioxide, a gas that rises to the surface as a stream of bubbles. Rocks that don’t contain calcium carbonate won’t fizz.
What happens when Limestone is mixed with water?
When this CaO, ie., Calcium Oxide when added to water, will give lime water (ie., Calcium Hydroxide) with liberation of heat. It is an EXOTHERMIC REACTION.
Why does limestone have fewer above ground sources?
Regions overlying limestone bedrock tend to have fewer visible above-ground sources (ponds and streams), as surface water easily drains downward through joints in the limestone.
Where does the calcium carbonate in limestone come from?
Travertine is a banded, compact variety of limestone formed along streams, particularly where there are waterfalls and around hot or cold springs. Calcium carbonate is deposited where evaporation of the water leaves a solution supersaturated with the chemical constituents of calcite.
How does the solubility of limestone lead to karst landscapes?
The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock.

Where does the limestone in the ocean come from?
Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water. What Is Limestone?
What is the chemical composition of a limestone rock?
What is Limestone? Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3. It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
