Is true or false limestone can be separated from fossils through the use of vinegar?

In most cases both the limestone AND the fossil will be dissolved by the vinegar (eg a crinoid in Carboniferous limestone), so no. However, some fossils (eg echinoderms in the Chalk) are silicified and in these cases dissolving the limestone in vinegar will expose the fossil in spectacular detail and in other cases the fossil will dissolve more slowly than the matrix, so yes. .
In other words there is NO true or false answer, fossil preparation and conservation is a discipline in itself.

If you put vinegar on limestone does it sizzle?
Yes, when vinegar comes in contact with limestone, a chemical reaction occurs that releases carbon dioxide gas, resulting in sizzling or fizzing. This reaction is due to the acidic nature of vinegar (acetic acid) reacting with the calcium carbonate in limestone.
What substance bubbles when vinegar is added to it?
The rock that fizzes when applied to vinegar is MARBLE, you will have to grind it up into powder first though. Edited by Sjheerts: actually no it is not marble. it is something inside the marble. it is called calcite
if you have olive oil vinegar and sugar water and herbs how would you separate them?
1. Vinegar, the sugar dissolved in vinegar, herbs are separated by decantation from oil. 2. Herbs are separated from the mixture by filtering. 3. After the evaporation of the vinegar solution sugar remain as a solid residue.
Why does limestone turn into a powder when in vinagar?
When limestone, which is composed of calcium carbonate, reacts with vinegar (which contains acetic acid), a chemical reaction occurs that produces carbon dioxide gas. This gas bubbles through the solution and breaks the limestone down into calcium acetate, water, and carbon dioxide. The physical appearance of the limestone changes to a powdery form due to the breakdown of the solid structure as it dissolves.
Can a mixture of vinegar and salt be separated by mechanical separation?
Oil and vinegar are a mixture. After a while they will separate.
Is it true or false that limestone can be separated from fossils through the use of vinegar?
True
Is it true or false that limestone can be separated from fossils through the of vinegar?
True. Vinegar contains acetic acid which can dissolve the calcium carbonate in limestone, making it possible to separate the fossils from the limestone.
Can limestone be separated from fossils by using vinegar?
When you put limestone into vinegar, it will shift around and sometimes create bubbles.
Do scientists use the chemical properties of vinegar to dissolve limestone surrounding fossils?
think it yourself
How are properties used?
Substances in some mixtures can be separated by physical means. As you read in Chapter 11, you can separate salt and pepper because they have different physical properties. Substances may also have different chemical properties that can be used to separate them from one another.Scientists who study dinosaur fossils and other fossils use chemical properties to separate mixtures. Fossils are often scattered throughout limestone. It can be difficult to chip limestone off a fossil without damaging the fossil. However, limestone can be dissolved by vinegar. A bubbling reaction occurs. Fossils, which are made of a different kind of rock, do not react with vinegar as quickly. So scientists sometimes use vinegar or similar chemicals to separate fossils from rock.Separating Metals from OresOres are rocks that include metals combined with other substances. People rely on chemistry to release metals from their ores. For example, iron ore contains iron oxide. Heating iron ore in a hot furnace with solid carbon allows the iron to separate from the oxygen in the ore. The resultThe fossil does not react quickly with vinegar, but the limestone around the fossil does. What evidence of this reaction can you detect?is pure iron and carbon dioxide. This process works because iron has the chemical property of bonding to oxygen less strongly than to carbon.In this blast furnace, iron is separated from iron ore. The process relies on the different chemical properties of the substances heated here

Can vinegar be separated by filtration yes or no?
The answer will depend on what it needs to be separated from. Vinegar can certainly be separated from stones by filtration!

What happens when you mix vinegar with calcite?
When vinegar reacts with limestone, the limestone will fizz and form bubbles. As the reaction continues, vinegar will dissolve the limestone. The product made is carbon dioxide.
Would limestone raise pH of vinegar?
Yes, because limestone neutralize acetic acid.

What kind of igneous rocks that formed a bubbles when putting a vinegar?
limestone
