What is salts hardness on the hardness scale?
The Mohs hardness of sodium chloride is 2,5.
What salts can cause hardness of water?
calcium and magnesium
Do Calcium bicarbonate salts cause hardness to the water?
Yes. it causes temporary hardness of water, which can be generally removed by boiling water.
Why Nacl and Kcl does not affect hardness of Water?
Because they are salts and thus are neutral. Also- water is also neutral.Improve:The above answer is not correct. Neutrality is not the issue. The reason is that sodium and potassium salts are readily soluble and will not precipitate out under normal conditions and so do not cause scale to build up in pipes and boilers. They also do not react with soap to form a scum and inhibit lathering.The sulphate, carbonate and chloride salts of calcium and magnesium are responsible for the hardness of water. They cause something called 'permanent hardness' which is manifested by the interference with soap lathering and the formation of scum. This is due to the presence of the calcium and magnesium ions in the water which causes the precipitation of insoluble stearates from the soap. Sodium and potassium ions do not cause this effect.The other type of hardness called 'temporary hardness' is mainly due to carbonate and bicarbonate salts of calcium and magnesium. Calcium and magnesium carbonate are less soluble in hot water than cold and will precipitate out in hot water pipes and boilers forming limescale. This is because the carbonate salts in tap water are in equilibrium with bicarbonate salts and the heating drives off carbon dioxide and breaks down the bicarbonate to the much less soluble carbonate.
What is the role of the bone salts and organic matrix in making bone both hard and flexible?
Bone salts (calcium, mainly) lend hardness; the protein-rich organic matrix permits some flexibility
How do prepare hard water?
To prepare hard water, simply dissolve calcium and magnesium salts like calcium chloride or magnesium sulfate in regular water. The concentration of these salts determines the hardness of the water. The dissolved salts will increase the mineral content of the water, making it hard.
The hardness of bone is due to what?
The hardness of bone is due to the calcium salts deposited in it.The exceptional hardness of bone, which allows it to resist compression, is attributed to the presence of inorganic hydroxyapatites. Hydroxyapatites such as calcium phosphates are particularly important for bone hardness. Organic substances such as collagen fibers contribute to tensile strength, but not to hardness.the presence of inorganic hydroxyapatites.
What is the role of bone salts and the organic matrix in making the bone both hard and flexible?
Bone salts, such as calcium and phosphorus, provide hardness to bones by forming a mineralized matrix. The organic matrix, composed mainly of collagen fibers, gives bones flexibility by providing a framework for mineral deposition. Together, bone salts and the organic matrix work synergistically to make bones both strong and flexible.
Why only magnisium sulphate and calcium sulphate cause hardness of water not sodium sulphate?
Magnesium sulfate and calcium sulfate cause hardness in water because they are slightly soluble in water, leading to the presence of excess ions in the water. Sodium sulfate, on the other hand, is highly soluble and does not produce excess ions that contribute to water hardness.
What is the function of calcium salts?
Calcium salts play a vital role in the formation and maintenance of healthy bones and teeth, as well as in muscle function, nerve transmission, and blood clotting. They are also used as a dietary supplement to help prevent or treat calcium deficiency.
Water hardness due to?
Water hardness is due to high levels of minerals, primarily calcium and magnesium, present in the water. These minerals can accumulate in water sources through contact with rocks and soil, leading to increased hardness. Water hardness can impact the taste, quality, and effectiveness of soaps and detergents.
The salts that form tiny crystals in the intercellular matrix of bone tissue consist largely of?
The salts that form tiny crystals in the intercellular matrix of bone tissue consist largely of calcium and phosphate ions, specifically in the form of hydroxyapatite. These salts provide the bone with its strength and hardness, contributing to its overall structure and function.
