At APEC, we strive to provide the best drinking water available to everyone. Even if it means offering a free system to those in need. Hard water
Hard water contains a significant quantity of dissolved minerals, such as calcium and magnesium. In general, hard water is not harmful for health. In fact, it may confer some benefits because it is rich in minerals and reduces the solubility of potentially toxic metal ions such as lead and copper. However, there are some industrial applications where hard water may lead to inefficiencies or damage to containers and pipes. In such instances, water softening methods are used. When water is softened, metal cations are exchanged for sodium ions.
Perhaps you have on occassion noticed mineral deposits on your cooking dishes, or rings of insoluble soap scum in your bathtub. These are not signs of poor housekeeping, but are rather signs of hard water from the municipal water supply. These ions do not pose any health threat, but they can engage in reactions that leave insoluble mineral deposits. These deposits can make hard water unsuitable for many uses, and so a variety of means have been developed to "soften" hard water; i. Mineral deposits are formed by ionic reactions resulting in the formation of an insoluble precipitate. This precipitate, known as scale, coats the vessels in which the water is heated, producing the mineral deposits on your cooking dishes.
Types of Hard Water. • Temporary hardness: –Caused by a combination of calcium ions and bicarbonate ions in the water. –Contain metal ion and CO. 2.
Although water is typically crystal clear, it contains minerals and chemicals. This article will look at the differences between the two types of water, as well as the pros and cons of each and what to know about water softening. The hardness of water is determined primarily by the amount of calcium and magnesium it contains. Higher levels of these and other minerals make water hard.
You've heard the terms "hard water" and "soft water, but do you know what they mean? Is one type of water somehow better than the other?
School Chemistry Notes: Explaining hard and soft water. The difference between hard water and soft water is explained and the causes and treatment of hard water fully explained. Extra Aqueous Chemistry Index:. Water cycle, potable water, water treatment, pollution, tests for ions. Colloids — sols, foam and emulsions. Gas and salt solubility in water and solubility curves. Calculation of water of crystallisation.
Orders made before 12 noon will be delivered the next day. We do not deliver on Sundays or Public Holidays. Our retail store is open Mon — Sat 11am — 5pm. The result is water with sodium ions instead of calcium ions. You will not know if the water is soft or hard by just looking at it.
The main difference between hard and soft water is the mineral content. Minerals commonly found in hard water are chalk, lime, calcium, and magnesium. Rain water is naturally soft but picks up these minerals as it runs through the ground. Hard water can cause problems in the house. Hard Water Problems Calcium, lime, and magnesium cause the problems commonly associated with hard water.
Hard water is water that has high mineral content in contrast with " soft water ". Hard water is formed when water percolates through deposits of limestone , chalk or gypsum  which are largely made up of calcium and magnesium carbonates , bicarbonates and sulfates. Iron oxides or iron carbonates can give a reddish brown colouration to hard water deposits. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers , cooling towers , and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters.
