What is the equation for marble chips and hydrochloric acid?
An investigation into how changing one variable influences the rate of reaction between marble chips and dilute Hydrochloric acid Planning Section When dilute hydrochloric acid reacts with marble chips the following reactions occurs: CaCO3 + 2HCL = H2O + CO2 This is the reaction we will be investigating.
What happens when marble is treated with hydrochloric acid equation?
Answer:Pieces of marble are thrown into hydro-chloric acid. Explanation: Calcium carbonate is dissolved by hydrochloric acid, thereby forming gaseous carbon dioxide: The combined reactants have a higher chemical potential than the combined products, i.e. the reaction takes place spontaneously.
Can you use marble chips instead of mulch?
Using marble chips as mulch has a few strong advantages over using organic mulch. White marble chips are also very high in pH and will leach into the soil over time, making it more alkaline. Don’t use marble chips as mulch around plants that prefer acidic soil.
Do white marble chips fade?
For another, marble doesn’t biodegrade, meaning it doesn’t have to be replaced from year to year the way organic mulch does. White marble chip mulch can be laid directly on the soil, but it’s much easier to manage if a sheet of gardening fabric is put down first.
How does the size of marble chips affect the rate of reaction between marble and hydrochloric acid?
As the reaction was taking place, the water in the measuring cylinder was being displaced – indicating that the calcium carbonate (in the form of marble chips) was displacing the hydrogen in the hydrochloric acid. Therefore, the trend of the reaction rate increasing as the concentration increased was shown.
What is the chemical formula for marble chips?
Answer: The chemical name of marble is calcium carbonate. It is an inorganic chemical compound with the chemical formula CaCO3. Calcium carbonate is a non-toxic and odourless compound commonly found as a white mineral which occurs naturally in chalks, limestones and marbles.
Why is dilute hydrochloric acid?
Dilute hydrochloric acid is often used in the extraction of basic substances from mixtures or in the removal of basic impurities. The dilute acid converts the base such as ammonia or an organic amine into water soluble chloride salt.
