One effect of soap and detergent in hard water is it will not lather as well as it does in soft water. This can affect the way the soap or detergent cleans in hard water making them less effective.
Soaps are sodium or potassium salts of long-chain fatty acids. Hard water contains calcium and magnesium ions. When soaps are dissolved in hard water, these ions displace sodium or potassium from their salts and form insoluble calcium or magnesium salts of fatty acids. These insoluble salts separate as scum. This is the reason why soaps do not work in hard water.
Hard water does not produce lather. So soap does not work effectively with hard water as soap does not form a good lather with hard water.
Hard water contains the salts of calcium and magnesium, which neutralize the soap. So that more or less amount of soap is precipitated before you get the effect of soap on the water. Only after you have wasted the certain amount of soap, you get the foam in the water. The ability of soap to clean the clothes comes only after foam formation.
Soap scum is calcium soap of fatty acids. It is the result of soap in hard water-- the fatty acids in soap bond with the calcium ions in hard water and create an insoluble compound.

The reason detergents are more effective than soap for cleaning hard water has to do with their ingredients and their function. Most detergents have cleaning properties that are able to combat hard water and mildew. The function of soap, however, is less complex. The function of water is to make water even wetter than what it is. This does not necessarily mean it contains cleaning properties.

Hard water is any water containing an appreciable quantity of dissolved minerals. Soft water is treated water in which the only cation (positively charged ion) is sodium Soap is less effective in hard water because its reacts to form the calcium or magnesium salt of the organic acid of the soap.

Hard to find Silka papaya soaps are usually sold for around $5 for a 15 grams bar of soap. There is also Likas Papaya Soap which is less aromatic but equally effective.
A soap is an organic molecule that has a polar/hydrophilic end and a nonpolar/hydrophobic end. The polar end typically has a hydroxyl functional group, which acts like a weak acid in water. Hard water is water that has a relatively large solute load, typically calcium, magnesium and other metals. When you add a soap to hard water, the metal ions in the water attach themselves to the polar end and you get a precipitate of the salt form of the soap. This inactivates the soap. However, if you add enough soap, you will effectively "soften" the water by pulling enough metal ions out of solution to still have active soap molecules in the water.

Usually soap holders or soap dispensers are the best for areas with hard water.

soft water:1. makes lather with soap faster.2. use a lot of water.hard water:1. makes lather with soap in very less amount.2. soap is wasted.3. chlorides, sulphates and bicarbonates of Ca and Mg are responsible.
