Carbonate hardness, also known as temporary hardness, is due to the presence of bicarbonate and carbonate ions in water. Noncarbonate hardness, also known as permanent hardness, is caused by the presence of sulfate, chloride, and nitrate ions in water. Both types of hardness contribute to the overall hardness of water, affecting its suitability for different uses.
The hardness.
A carbonate residue is a chemical deposit left behind by the evaporation of water containing dissolved calcium carbonate, while an impression is a mark or indentation made by an object pressing into a surface. Carbonate residue is a physical deposit, whereas an impression is a mark created by pressure.
Calcium carbonate is a chemical compound commonly found in rocks, pearls, and eggshells, while strontium carbonate is a similar compound that contains strontium instead of calcium. They both have similar chemical properties but strontium carbonate is slightly more soluble in water than calcium carbonate. Strontium carbonate is often used in fireworks and ceramic glazes, while calcium carbonate is commonly used as a dietary supplement and in construction materials.
Mineral hardness measures a mineral's resistance to scratching, while streak is the color of the powdered form of a mineral. Hardness is determined by the Mohs scale, while streak is identified by rubbing the mineral across a porcelain plate to see the color left behind.
between 7 and 8
what is the difference between Shore-A Hardness & Barcol Hardness
The difference between strength and hardness is that the strength refers to the force that is present between the bonds. Strength attributes to how strong or weak the force between the bonds. Hardness refers to the nature of the force, which basically is how rigid or flexible the bonds between particles.
It is a difference between the hardness, generally expressed in the Mohs scale.
micro is on a small scale and macro on a larger scale

Temporary hard water contains bicarbonates that can be removed by boiling, while permanent hard water contains sulfates or chlorides that cannot be removed by boiling. Temporary hardness can be easily treated with boiling or using a water softener, while permanent hardness requires more advanced treatment methods such as ion exchange or reverse osmosis.
The hardness.
The main difference between water and ecowater is the hardness rating difference. For water testing and filter options, see your local water specialist.
Both are two different scales of hardness measurement.
Hardness measures a material's ability to resist permanent deformation, whereas brittleness measures a material's tendency to fail or break without undergoing significant deformation. In other words, hardness relates to the resistance to scratching or indentation, while brittleness relates to the tendency to fracture.
Hardness usually is used to describe the difficulty of separating the molecules of a material or substance. The texture is simply how the material or substance feels.
There are some differences between hardness and hardenability. Hardness is the surface property of material to give resistance to the penetration or plastic deformation and it is measured by one of the tests......Rockwell hardness test,Brinell hardness test and Vicker hardness test. On the other hand,hardenability is defined as the ability how the material would be hardened and it is measured by Jominy hardenability test.
