Main Difference

The main difference between Hard Water and Soft Water is that Hard Water is the water that contains a considerable amount of several dissolved minerals, whereas Soft Water is the water that contains sodium ions only.

Hard Water vs. Soft Water

Hard water is the quality of water, which contains a considerable amount of several dissolved minerals salt, i.e., magnesium and calcium; on the other hand, soft water contains only sodium ions in it. Hard water is come through soft water, which comes down from land by rainwater and dissolved many salts and becomes hard water; whereas, soft water a natural water which is rainwater.

Hard water is sometimes preferable for drinking purposes because of dissolved substances; on the flip side, soft water does not prefer for drinking purposes due to salty taste. Hard water mostly uses for drinking; on the flip side, soft water does not apply for drinking.

Hard water, when it gets boiled, settled down many minerals; on the other hand, soft water, when it gets heated, do not settle many minerals except sodium. Hard water does not produce lathery when treated with soap; on the flip side, soft water gives good leathery when treated with soap.

Hard water, when used in washing and bathing purposes it gives scum and dull look; on the flip side, soft water is best in using washing and bathing purpose. Hard water feels dense to touch; on the other hand, soft water feels slimy to touch.

Hard water when used in bathing the hair and skin becomes dry; on the flip side, soft water, when used in washing the hair and skin become smooth. Hard water is the water which extracts from underground water, whereas soft water is the water coming down as rainwater.

What is Hard Water?

Hard water is the water that contains many mineral ions, inconsiderable amount. Hard water mostly extracts from underground. Hard water contains mainly ions like calcium and magnesium and other ions etc.

Hard water is preferable for drinking purposes due to it contains many useful ions that are essential for human life. Its taste is pleasant, and human beings use it for drinking. It gives many precipitates when it gets boiled, and the mineral precipitates do use for different purposes.

Hard water does not give good lathering with treated with soap. When it uses in washing the dishes and clothes, they become dull, and scum is visible on plates. When it uses in bathing purposes, the hairs are going to dull.

Hard water feels denser when we touch it because it contains many mineral ions. The best example of hard water is the water extracted from the underground. Hard Water dissolved minerals sometimes deposited in the veins or arteries and causes disturbance like blood pressure disease.

What is Soft Water?

Soft water defines as the water which contains only sodium ions. It is present in nature as the rainwater, which goes down to the earth and mixing many useful minerals and becomes hard water. It is not preferable for drinking purposes because it does not contain essential minerals.

Soft water taste is salty due to sodium ions present in it. When it gets boiled, the only precipitate is a sodium ion. By heating it, the precipitate of sodium ion use for salt preparation and the manufacturing of many useful compounds.

Soft water gives good lathery production when treated with soap. It uses in washing the dishes and clothes on its excellent working. It also applies to bathe, and our skin becomes fresh.

Soft water feels light when we touch it due to less density, and fewer ions are present. The best example of soft water is the water present naturally and the rainwater. Soft water is not useful for drinking purposes due to the only presence of sodium ions.

Key Differences

  1. Hard water defines as the water which contains many dissolved ions; on the other hand, soft water defines as the water which contains only sodium ions.
  2. Hard water formerly extracts from underground water; on the flip side, soft water originally came through rainwater.
  3. Hard water is preferable for drinking purposes; whereas, soft water is not preferable for drinking purposes.
  4. Hard water is good for drinking purposes due to its better taste; on the other hand, soft water is not suitable for drinking due to salty taste.
  5. Hard water usually gives mineral ions when it gets boiled; on the flip side, soft water, only sodium ions when it gets heated.
  6. Hard water produces reduced lather while using soap; on the other hand, soft water produces good lather while using soap.
  7. Hard water is feeling dense due to many mineral ions are present; on the flip side, soft water is feeling light due to less density.
  8. Hard water gives dull and produces scum when used in washing purposes; on the other hand, soft water does not provide a dark look.
  9. A hard water example is the water extract through underground; on the other hand, a soft water example is a water that comes through rainfall.

Conclusion

Hard water is the water that contains poly mineral ions like calcium and magnesium etc. and soft water is the water that contains only sodium ions in it. Hard water is preferable for drinking, and soft water does not prefer for drinking purposes due to salty taste.
