Hardness of water is defined by its content of [Metal]2+ and M3+ ions that will precipitate in alkali (OH-) or with (bi)carbonate when heated above 60oC.
Most common ions Ca2+, Mg2+, (Mn2+ and Fe2+,3+)
Soft or hard water has to do with the amount of dissolved minerals in water and what those minerals are. "Harder" water has more dissolved minerals (like calcium.)
Calcium and magnesium are typically found dissolved in large quantities in hard water. These minerals can cause a buildup of scale in pipes, appliances, and fixtures over time.
no
You think probable to hard water.
No. Hard water is water with high amounts of dissolved calcium and magnesium.
the difference is that soft water contains no dissolved minerals.the hard water contains dissolved minerals
Hard water is just a term. Various salts and minerals are dissolved (are solutes) in hard water. These may include Calcium, Iron, Chloride Ion, Sodium, and Potassium.
Hard water contains high levels of dissolved minerals such as calcium and magnesium, which can lead to scale buildup in pipes and appliances. Soft water, on the other hand, has been treated to remove these minerals, making it less likely to cause scale buildup. The main equation to differentiate hard water from soft water is the presence of these dissolved minerals in hard water.
Depends where you live, the more calcium chloride dissolved in the water the harder it is
Dissolved minerals in the water. In most cases it is better to water your garden with hard water instead of treated water. The plants typically like the minerals found in hard water.
To find out how much solid is dissolved in pond water, you can perform a process called gravimetric analysis. This involves evaporating the water from a known volume of pond water and then measuring the mass of the residue left behind, which represents the dissolved solids. By comparing the initial and final masses, you can calculate the amount of solid dissolved in the pond water.
Hard water is a mixture: water containing calcium and magnesium carbonates, also some sulfates or chlorides.
