Does the hardness of water depend upon the metal or non metal ion of the mineral?

The hardness of water depends primarily on the concentration and chemical identities of the metal cations dissolved in the water. The non metal ions dissolved in the water have little effect unless the particular ions are capable of forming coordinate covalent bonds to the metal ions.

Is talc a metal?
Talc is not classified as a metal. It is a very soft hydrous silicate mineral composed of magnesium, silica and water
Wat salt is responsible for temporary and permanent hardness of water?
Temporary hardness of water: CaHCO3, MgHCO3 Permanent hardness of water: CaSO4, MgSO4
Two elements found in hard water?
Typicall water hardness is caused from calcium and magnesium compounds dissolved in the water. The term "hard water" is used to describe water that has a high mineral content, usually calcium and magnesium in the form of carbonates, but may include several other metals as well as bicarbonates and sulfates, (water with a low mineral content is known as soft water). A high enough concentration of these metals in your water can cause white lime scales on surfaces which the water comes into contact with. Total water 'hardness' is reported as ppm w/v (or mg/L) of calcium carbonate (CaCO3). Water hardness usually measures the total concentration of calcium and magnesium, the two most common metal ions, although in some locations around the world iron, aluminium, and manganese may also be present at elevated levels. Calcium usually enters the water as either calcium carbonate (CaCO3), from limestone or chalk, or from mineral deposits of calcium sulfate (CaSO4).
Water hardness due to?
We often talk about water of different qualities in our daily life and very often we are faced with certain problems caused by hard water. The total hardness (TH) consists of all calcium (Ca) and magnesium (Mg) salts dissolved in it. Water hardness consists of two types of hardness, carbonate, and non-carbonate. Carbonate hardness consists of calcium and magnesium bicarbonates Ca(HCO3)2 and Mg(HCO3)2. Non-carbonate hardness consists of all their other salts such as chlorides, nitrates, sulfates, etc. After washing in hard water, stains from precipitated limescale remain which are very difficult to remove, textiles washed in “hard” water become stiff due to the deposition of limescale on fine textile fibers, and washing in hard water consumes more detergents due to the reaction of detergents with hardness salts and, creation of insoluble soaps – soap scum. Using soft water can solve all these problems.
Which minerals dissolve in water?
Rock salt is a mineral that is easily soluble in room temperature water.
Is Hardness or Specific gravity compares the weight of a mineral with the weight of an equal amount of water?
Hardness compares the weight of a mineral with the weight of an equal amount of water
The hardness of water is a measurement of how acidic it is?
no it's the mineral content
The hardness of water is a measurement of how acidic it is.?
no it's the mineral content
What happens when heated metal is suddenly immersed in water?
The metal increases in hardness, a mechanical property. The process which transforms the metal hardness is called "quenching".
What is the definition for the hardness of a mineral?
Hardness - measure of how easily a mineral is scratched.
Why temporary hardness is removed from water by boiling but permanent hardness is not?
Permanent hardness is hardness (mineral content) that cannot be removed by boiling. It is usually caused by the presence in the water of calcium and magnesium sulphates or chlorides which become more soluble as the temperature rises.
What is the name of a rose colored mineral with a mass of 53 grams and when placed in water its displaces a volume of 20 cubic centimeters of water what is the hardness or this mineral?
most likely it is quartz
What is hardness in relation to water quality?
Hardness of water pretains to the concentration of minerals and other trace elements in your local water supply. Well water-such in my area is "very hard"-meaning it contains a large amount of iron and other minerals-when boiled down in a pot of the water on your stove-it will leave a deposit on the pan once the water has boiled away. A water softener helps filter out these particles.
How does hard water differs from soft water?
Hard water content of 2+ and 3+ mineral metal ions is high. Most common hardness is result of Ca2+ and Mg2+ ions in ground- or surface water. Soft water on the other hand, contains lower levels of calcium and magnesium. Rain water is soft.
Is tropical water hard water?
Tropical refers to the temperature of the water; aquariums can be tropical and hard, or tropical and soft water. Water hardness is simply a measure of the mineral content of the water.
What is a mineral made out of?
It is made out of metal and carbon dioxide. The CO2 (water) evaporates from this making it the silver mineral.
How often do you check your calcium hardness?
The recommended frequency for checking calcium hardness in swimming pools is once a month. Other water tests will depend on how often the pool is used.
