Although water is typically crystal clear, it contains minerals and chemicals.

School Chemistry Notes: Explaining hard and soft water.

What is the difference between hard and soft water?

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.

Here are some of the most common issues:. Bottle Test Gather a clean empty plastic bottle with a cap and dish washing liquid. Remove the cap and fill the bottle about halfway. Add about 5 drops of the dish washing liquid and shake vigorously. You should see foam forming. If the foam stays, the water is not hard. If the foam quickly dissipates, the water is hard. Water Test Kit A hard water test kit will indicate the hardness of the water with a good accuracy. To perform the test you start out by filling a vial with the water in question.

Then add a drop of solution and shake well for 5 to 10 seconds. Keep adding one drop and shaking until a half inch of suds is sustained.

Each drop used represents 1 grain of hardness. Anything less than 3 grains of hardness is at most slightly hard and does not need to be remedied.

Anything higher than 3 you might want to treat. Water Test from a professional. Hard Water Solutions If you do have hard water and the resulting problems, the best solution is a water softener. These devices run the water through a resin bed to exchange the hard ions with soft ones. The resin bed will slowly buildup up hardness ions and need to be cleaned, as you might already know the Kinetico systems clean themselves.

The salt in the bin is the key chemical for this cleaning process a. Depending on the hardness of the water, this regeneration process is run on a timed basis triggered by a control panel. More efficient systems work based on the usage of water and not on a clock. While these are temporary remedies, will help you out on the short term. We highly recommend a Water Softener or Treatment for the prolongation of your appliances and plumbing.

Large amounts of sediment are present at the bottom of the water heather or other appliances including faucets.

Soft water

Soft water is surface water that contains low concentrations of ions and in particular is low in ions of calcium and magnesium. Soft water naturally occurs where rainfall and the drainage basin of rivers are formed of hard, impervious and calcium-poor rocks. The term may also be used to describe water that has been produced by a water softening process although such water is more correctly termed softened water. In these cases the water may also contain elevated levels of sodium and bicarbonate ions. Because soft water has few calcium ions, there is no inhibition of the lathering action of soaps and no soap scum is formed in normal washing. Similarly, soft water produces no calcium deposits in water heating systems.

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.

Hard Water vs. Soft Water: Which One Is Healthier?

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.

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.
