Chalk is made out of Calcium Sulphate and it dissolves in weak acids which means it is a weak chemical to acids. So the vinegar wich is a typr of an acid dissolves the chalk with cool foams foaming in the jug or a cup.
because of the acid in the vinegar
EDIT(Dr.J.): Actually, chalk is mostly calcium carbonate, not calcium sulphate. The carbonate reacts with acetic acid (vinegar) to create CO2 and H2O as follows:
CaCO3 + 2CH3COOH ==> Ca(CH3COO)2 + 2H2CO3 ==> 2CO2 + 2H2O
Chalk is primarily composed of calcium carbonate, which tends to dissolve in acidic solutions. When placed in acidic liquids, such as vinegar, the acid reacts with the calcium carbonate to form soluble calcium acetate, carbon dioxide gas, and water, leading to the dissolution of the chalk.
It acually matters on how big the chalk is. If it's small, it will erode away slowly. Ask again with a measurment next time.
add. But your blackboard chalk may not dissolve at all, for it is possibly made of CaSO4, not CaCO3.
Only completely in lemon juice, a tiny bit in vinegar, and not at all in water.
Chalk is made of calcium carbonate, meaning it eventually will dissolve in vinegar.

What do you mean like dissolve like?
For example polar liquids dissolve polar solids, nonpolar liquids dissolve nonpolar solids.
Will salt dissolve faster in vinegar or salt?
Depends on the pH of the water but it would dissolve faster in fresh water because there isn't as much stuff in solution. true... but it took me about 8.30 seconds to dissolve with the perfect pH.....
How much time does it take to dissolve sidewalk chalk in soda?
It typically takes several hours for sidewalk chalk to dissolve in soda, depending on the size of the chalk piece and the type of soda used. The process may be accelerated by stirring or crushing the chalk pieces.
Would sidewalk chalk dissolve in gasoline?
Yes, sidewalk chalk is made of calcium carbonate which is not soluble in gasoline. The chalk would likely not dissolve but it may break down and form a sludge or residue in the gasoline. It is not recommended to mix chalk with gasoline as it can cause clogging and damage to the engine.
How does water dissolve chalk?
Rather badly.
How fast does half a stick of chalk dissolve in water?
In order to dissolve chalk in water, vinegar needs to be added. The vinegar has acid in it that eats away at the chalk to dissolve it.
Will chalk dissolve in sprite?
Chalk will not dissolve in Sprite because chalk is made mostly of calcium carbonate which is not soluble in water. The chalk will remain solid and will not mix with the liquid.
If you add sugar to water and put a chalk inside will it dissolve?
No, the chalk will not dissolve in water even if sugar is added. Chalk is made of calcium carbonate, which is insoluble in water. The sugar will dissolve in the water but not the chalk.
Does Coca-Cola dissolve hair?
No, Coca-Cola will not dissolve hair!! How do i know this? Well, I actually just did my Science Fair Project to see if hair will dissolve in certain liquids and coca-cola was one of my liquids. the Coca-Cola only changed the color of the hair but it did not dissolve it. Bleach will dissolve it in a matter of hours!!
Can chalk dissolve in lemon juice?
Yes lemon juice can dissolve chalk and other things like the enamel on your teeth
Is chalk dissolve in water?
No! its insoluble
Can liquids dissolve into other liquids?
yes they can but it depends on the liquids
What do you call liquids that dissolve liquids?
insoulble
What do you mean like dissolve like?
For example polar liquids dissolve polar solids, nonpolar liquids dissolve nonpolar solids.

Can acid rain dissolve chalk?
Yes, acid rain can dissolve chalk because chalk is made of calcium carbonate which reacts with acid to form calcium ions, carbon dioxide, and water. Over time, repeated exposure to acid rain can break down and dissolve chalk surfaces.
