Word equation for the reaction between calcium carbonate and methanoic acid?

Calcium carbonate reacts with methanoic acid to produce calcium methanoate, carbon dioxide, and water. The word equation for this reaction is: calcium carbonate + methanoic acid → calcium methanoate + carbon dioxide + water.


How do you separate calcium carbonate from sand?

Both the components in the mixture are insoluble in water. However, calcium carbonate reacts with hydrochloric acid to form calcium chloride (which is soluble in water) whereas the sand remains unchanged. Sand can now be separated by filtration. Calcium carbonate is recovered back by treating the filtrate (calcium chloride) with sodium carbonate. After filtration is again carried out, what you have on the filter paper is calcium carbonate.


How is Calcium carbonate used to neutralise acid emissions from power stations?

Calcium carbonate is used in power stations to neutralize acid emissions by reacting with sulfur dioxide and nitrogen oxides in the flue gas. The reaction forms calcium sulfate, calcium nitrate, and water, which are less harmful and can be safely disposed of. This process helps reduce the environmental impact of acid rain caused by these acidic emissions.


What experiment can you do to find out how much calcium carbonate there is in limestone?

To determine the amount of calcium carbonate in limestone, you can perform a titration using hydrochloric acid. By reacting a known mass of limestone with hydrochloric acid, you can measure the volume of acid required to neutralize the calcium carbonate. This information can then be used to calculate the amount of calcium carbonate present in the limestone sample.


Does limestone react to acid?

No. It is a sedimentary rock. However, unlike sandstone which is also a sedimentary rock, it is primarily composed of calcium carbonate which can be eaten away by acid (like acid rain) gradually with time.

What chemical makes orange juice dissolve egg shells?

Orange Juice (Citric Acid) Egg Shells ( Calcium Carbonate). Remember the general reaction eq'n Acid + Carbonate = Salt + Water + Carbon dioxide.


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.


How much citric acid and calcium carbonate make calcium citrate?

To make calcium citrate, you would typically combine one molecule of citric acid with two molecules of calcium carbonate. So, for every 1 molecule of citric acid, you would need 2 molecules of calcium carbonate to produce calcium citrate.


How does citric acid remove lime scale?

Citric acid breaks down the calcium carbonate in limescale through a process called chelation. The acid binds to the calcium ions, which loosens the bonds holding the scale together, making it easier to dissolve and remove.


Can hydrochloric acid make calcium carbonate bubble?

Yes, when hydrochloric acid reacts with calcium carbonate, the calcium carbonate will dissolve, producing carbon dioxide gas. This gas release can cause bubbling or foaming in the solution.


Can chalk dissolve in HCl and why?

No, chalk (calcium carbonate) does not dissolve in hydrochloric acid (HCl) because calcium carbonate is insoluble in acids. When HCl is added to chalk, it will react with the calcium carbonate to form calcium chloride, water, and carbon dioxide gas, but the chalk itself will not dissolve.


Why do egg shells dissolve in hydrochloric acid?

Egg shells are made of calcium carbonate, which reacts with hydrochloric acid to form carbon dioxide, water, and calcium chloride. This reaction causes the egg shell to dissolve as the calcium carbonate breaks down into its component parts in the acid solution.


What happens when you further dissolve calcium carbonate in acid?

When you further dissolve calcium carbonate in acid, it will react with the acid to form soluble calcium salts, carbon dioxide gas, and water. This process will continue until all the calcium carbonate has reacted, leaving a clear solution containing the soluble calcium salt.


Why do you use hydrochloric acid to separate calcium carbonate from sand but not sulphuric acid?

Hydrochloric acid reacts with calcium carbonate to form calcium chloride, carbon dioxide gas, and water, which helps dissolve the calcium carbonate. On the other hand, sulfuric acid does not react with calcium carbonate as effectively as hydrochloric acid, making it less efficient for separating calcium carbonate from sand.


What substances can neutralize citric acid?

Substances that can neutralize citric acid include bases such as sodium bicarbonate (baking soda) and calcium carbonate (found in antacids). When these bases react with citric acid, they form water, carbon dioxide, and a salt, which helps to neutralize the acidity of the citric acid.


Why does chalk dissolve in lemon juice?

Lemon juice contains citric acid. Citric acid is a weak acid that has the chemical formula of C6H8O7. It reacts with chalk, which consists of calcium carbonate (CaCO3). Whenever an acid reacts with a base, a salt and water are formed. Salts can dissolve in water (they are aqueous). Therefore, when chalk reacts with lemon juice, water and aqueous sodium citrate are formed. The sodium citrate dissolves into the water.


What are the effects of acid rain on calcium carbonate?

Acid rain can dissolve calcium carbonate, a common component of rocks like limestone. This process leads to the deterioration of buildings and monuments made of calcium carbonate, affecting their structural integrity. Additionally, the dissolution of calcium carbonate in bodies of water can disrupt the balance of calcium ions, affecting aquatic ecosystems.
