Chalk (used for writing on black board) contains Calcium carbonate so HCl decomposes the carbonate with bubbles of carbon dioxide gas.

CaCO3 + 2HCl ------> CaCl2 + CO2 + H2O

Will citric acid dissolve chalk?

No, citric acid will not dissolve chalk. Chalk is mainly composed of calcium carbonate, which is insoluble in citric acid. An acid like hydrochloric acid would be more effective in dissolving chalk.


Chalk reacts with hydrochloric acid when mixed Will pounding the chalk into powder increase the rate of reaction?

Yes, pounding chalk into powder will increase the rate of reaction with hydrochloric acid. This is because crushing the chalk into a powder increases its surface area, allowing more of it to come into contact with the hydrochloric acid and react.


When you hydrochloric acid and chalk together is it physical or chemical change?

When you mix hydrochloric acid with chalk, a chemical change occurs. This is because the acid reacts with the calcium carbonate in the chalk to form carbon dioxide gas, water, and calcium chloride. This is a chemical reaction that results in the formation of new substances.


Does hydrochloric acid have a more dramatic effect on palladium or platinum?

Hydrochloric acid has a more dramatic effect on palladium compared to platinum. Palladium forms soluble complexes with hydrochloric acid, while platinum is more resistant to attack and does not readily form soluble compounds with hydrochloric acid.


Which gas can evolve when an acid reacts with chalk?

Carbon dioxide gas evolves when an acid, such as hydrochloric acid, reacts with chalk, which is primarily made of calcium carbonate. This reaction releases carbon dioxide gas, water, and calcium chloride.

Is gas produced when you add acid to chalk?

Yes, when an acid such as hydrochloric acid is added to chalk (calcium carbonate), it reacts to produce carbon dioxide gas, calcium chloride, and water. The carbon dioxide gas is the visible product of this reaction.


What gives off more carbon dioxide when mixed with hydrochloric acid - chalk or marble?

Important is the percentage of calcium carbonate (CaCO3) in the material. For an equivalent mass of pure chalk or pure marble the quantity of released carbon dioxide is the same - the chemical formula is the same.

What happens when water and chalk mix?

When a drop of dilute hydrochloric acid is placed on a piece of Chalk, the acid reacts with the calcite and forms bubbles of carbon dioxide. This "fizz" reaction is so characteristic of limestone than many geologists carry a small bottle of dilute hydrochloric acid into the field for a rapid and easy identification of limestone. During the reaction, the bubbles of carbon dioxide rise, then turn a brownish color, and then decrease in size. This is weird because the hydrochloric acid starts out as a white fizz.


Why is hydrochloric acid more corrosive to aluminum than sulfuric acid?

effect of concentration increase on the inhibition efficiency of organic inhibition on the conosion of aluminium in hydrochloric (Hcl) acid solution.


What happened to the chalk mixed with hydrochloric acid and being heated?

CaCO3,s + 2H+aq --> Ca2+aq + CO2,g + H2Oliq You don't need to heat it up, it goes very well at room temperature, even below freezing point. The reaction rate depends more on coarseness of the chalk and the concentration of HCl.
