Huhu.... i don't know (^_^)
The reaction between calcium carbonate (CaCO₃) and disodium edetate (Na₂EDTA) involves the chelation of calcium ions by EDTA. When disodium edetate is added to a solution containing calcium carbonate, it forms a stable complex with the calcium ions, resulting in the dissolution of calcium carbonate. This reaction is often used in analytical chemistry to quantify calcium levels or in various applications where calcium removal is desired.
When calcium reacts with sodium carbonate, calcium carbonate and sodium bicarbonate are formed. This reaction is a double displacement reaction where the cations and anions switch partners. Calcium carbonate is insoluble and precipitates out of the solution, while sodium bicarbonate remains dissolved.
Calcium and magnesium carbonates are sometimes added as anticaking agents.
To prove that a washing detergent contains calcium carbonate, you can perform a simple test using an acid such as vinegar. When vinegar is added to calcium carbonate, it produces carbon dioxide gas, which can be observed as fizzing or bubbling. This reaction confirms the presence of calcium carbonate in the detergent.
The reaction is:CaCO3 + H2SO4 = CaSO4 + CO2 + H2O
THE QUESTION !!! A student wanted to find the mass of calcium carbonate in an indigestion tablet. She crushed up a tablet and added an excess of HCL acid (25cm3 of 1.00 mol/dm3). She the titrated the excess against 0.5 mol/dm3 of NaOH requiring 25.8cm3 of the NaOH. Calculate the mass off calcium carbonate in the tablet.
When calcium carbonate is added to water, it will form a suspension where the calcium carbonate particles are dispersed in the water. While some of the calcium carbonate may dissolve into calcium ions and carbonate ions, the majority will remain as solid particles in the water.
When H2O is added to CaCO3 (calcium carbonate), it can cause a chemical reaction where calcium carbonate may dissolve to form calcium ions (Ca2+) and carbonate ions (CO3 2-). This can result in the formation of a solution containing calcium ions and carbonate ions.
Calcium carbonate dissolves in water through a process called dissociation. When calcium carbonate is added to water, it breaks down into calcium ions (Ca^2+) and carbonate ions (CO3^2-). These ions then interact with water molecules, causing the calcium carbonate to dissolve.
Over time soils on farms become acidic, calcium carbonate is added to fields to regulate the ph of the soil
When 15 percent hydrochloric acid is added to calcium carbonate, calcium chloride, carbon dioxide, and water will be formed. This is due to a chemical reaction where the acid reacts with the calcium carbonate to produce these products.
Calcium chloride. When carbonic acid is added to a solution containing calcium chloride, a white precipitate of calcium carbonate is formed due to the reaction of calcium ions with carbonate ions from carbonic acid.
Starts off as Calcium Carbonate , when heated the calcium carbonate becomes Calcium Oxide + Carbon Dioxide, the Calcium Oxide then reacts with water to produce Calcium Hydroxide and then when more water is added then filtered it becomes Calcium Hydroxide Solution, C02 is then added to form Calcium Carbonate again [:
Calcium carbonate is added to soil to raise its pH level and reduce acidity. This helps create a more neutral environment for plants to grow, as some plants prefer a slightly alkaline soil. Additionally, calcium carbonate provides essential calcium to plants for healthy growth and development.
Calcium carbonate is rather INsoluble, so there is no solution of it. I do not know why ammonium oxalate is added to a calcium carbonate solution. Calcium oxalate will then precipitate out of the solution. The ammonium and carbonate will create a weakly bond compound. Actually, more of the ammonium ion will be in solution as free ammonia and more of the carbonate ions will be in solution as free carbon dioxide. That is the nature of those two substances. So, you will have a solution that has a calcium oxalate precipitant on the bottom and is slowly giving off ammonia and carbon dioxide.
One chemical property that can be used to identify calcium carbonate is its reaction with hydrochloric acid to produce carbon dioxide gas, which causes effervescence. Additionally, calcium carbonate will turn a solution of calcium hydroxide milky when added, indicating the presence of carbonate ions.
When iodine is added to calcium carbonate, no significant reaction occurs between the two compounds. Iodine does not react with calcium carbonate because the two compounds have different chemical properties.
