Carbonate residue refers to the leftover deposits created by the reaction of carbonates with other elements in a material, while an impression is a mark or indentation made by a foreign object pressing into a surface. In geology, carbonate residue may indicate the presence of minerals, whereas impressions can reveal details about the object that made them.

What residue is left behind when copper carbonate is hot or cold?
When copper carbonate is heated, it decomposes to form copper oxide and carbon dioxide gas, leaving behind copper oxide residue. When copper carbonate is mixed with acids to produce copper salts, a blue residue may be left behind.
Is there a difference between residue on ignition vs. residue on evaporation?
Yes. The residue left is material that did not ignite or products of the ignition reaction.The residue remaining after evaporation is the non-volatile substances in the solutionsubjected to the evaporation.
If you heat calcium carbonate what gas will be given off?
I'm no specialist on this, but I'd say CO2. Leaving CaO as a residue of course...
What is difference between sulphated ash and residue on ignition?
Sulphated ash is the amount of inorganic residue left when a sample is ignited after treatment with sulfuric acid. On the other hand, residue on ignition is the amount of material left behind when a sample is ignited without any prior treatment. Sulphated ash is typically used for organic materials, while residue on ignition is often used for inorganic materials.
How do i find the mass of calcium carbonate in an indigestion tablet?
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.
What is the difference between a carbonate residue and an impression?
A carbonate residue is a chemical deposit left behind by the reaction of a carbonate compound with an acid, resulting in the release of carbon dioxide gas. On the other hand, an impression refers to a negative imprint or mark left behind on a surface due to pressure or contact with an object. While carbonate residues are formed through a chemical process, impressions are physical marks created by pressure or contact.
What is the difference between sulphated ash and residue on ignition?
The only difference between sulphated ash and the residue on ignition is the terminology. The residue on an ignition is sulphated ash.
What residue is left behind when copper carbonate is hot or cold?
When copper carbonate is heated, it decomposes to form copper oxide and carbon dioxide gas, leaving behind copper oxide residue. When copper carbonate is mixed with acids to produce copper salts, a blue residue may be left behind.
What is the chemical reaction between calcium carbonate and milk?
The chemical reaction between calcium carbonate and milk involves the formation of calcium ions (Ca2+) along with other products. The calcium ions may bind with proteins in milk, such as casein, forming complexes that can precipitate out of solution. This can result in the formation of a residue or sediment in the milk.
What gas is produced when copper carbonate decomposes?
When copper carbonate decomposes, it produces carbon dioxide gas along with copper oxide as a residue.
What is the blood red residue formed in a glass test tube when copper carbonate is heated vigourously with carbon?
Elemental copper.
Is there a difference between residue on ignition vs. residue on evaporation?
Yes. The residue left is material that did not ignite or products of the ignition reaction.The residue remaining after evaporation is the non-volatile substances in the solutionsubjected to the evaporation.
What is the difference between waste and residue?
Solid wastes are non-liquid materials ranging from municipal garbage to industrial wastes that contain complex and sometimes hazardous substances. Solid wastes also include sewage. Residue is greenhouse emissions.
What is the difference between salt water residue and fresh water residue?
The difference is that saltwater is salty, doesnt taste good, and your not supposed to swallow it. Also saltwater is good to gargle if you have a sore throat. In the other hand fresh water is healthy for you, cools you down, and you can swallow it. Also 70% of your body is made of fresh water.
If you heat calcium carbonate what gas will be given off?
I'm no specialist on this, but I'd say CO2. Leaving CaO as a residue of course...
What are two ways that you could tell the difference between pure water and salt water?
Taste Smell Melting Point Boiling Point Density Residue after it evaporates
How do you prove that a washing detergent contains calcium carbonate?
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.
