Why is CaCO3 taken as reference to measure hardness of water?
Because calcium carbonate is the most important impurity in water to produce hardness.
Wat salt is responsible for temporary and permanent hardness of water?
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
Why was Fredrich Mohs important?
He originally came up with the scale when classifying a private collection. He classified them by their physical characteristics rather than their chemical composition, using their relative hardness.
What are the two form of hardness found in water?
Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.
What is the name of the complexing agent used to determine the total hardness?
caco3
Why is CaCO3 taken as reference to measure hardness of water?
Because calcium carbonate is the most important impurity in water to produce hardness.
What does the Mohs hardness scale determine?
The hardness of MINERALS.
What do scientists use to determine mineral hardness?
The Mohs scale of mineral hardness is generally used to determine the hardness of a mineral. The Mohs scale rates the ability of mineral to scratch or be scratched by another mineral.
What type of hardness?
Hardness is a breaking strength measurement of pellet as multiparticulate dosage form prepared with water (granulation liquid). This hardness is a very important in assessment or characterization of pellet, a good hardness is preferable for coating step of pellet.
How do you test a mineral for hardness?
Well. You can do many things like use the Mohs Hardness Scale or determine the hardness by the streak.
Scientists use this to determine a minerals resistance to being scratched?
A mineral's resistance to being scratched is known as it's hardness. You can determine hardness by scratching it with another material whose hardness is already known. If it can be scratched, then the hardness is lower. If the unknown leaves a scratch on the known material, then its hardness is higher.
A scale used to measure the hardness of rocks?
The Mohs scale is used to determine the relative hardness of minerals.
What is used to to determine hardness of a mineral?
t58i4
What determine the hardness of fat at room temperature?
The type of fatty acids in the triglycerides, the amount of water present and if food additives are present.
Which does not cause hardness of water?
Magnesium sulfate (MgSo4) does not cause hardness of water.
Which scale is used to measure the hardness of mineral?
The Mohs scale is used to determine the relative hardness of minerals.
How do you get rid of water hardness?
Salt is sometimes used to remove water hardness. Borax and soda are generally used as well to remove water hardness.
