The soap attaches to, envelopes, the minerals in the water and so then it takes ALOT more soap to create suds, or in particular, a cleansing affect. The use of surfectants (water-softening agents) enables you to use less soap with normal tap water. While people think soft water makes it harder to wash off the soap, actually it is the opposite. The best cleaner in the world is "clean water", mineral free water, and it will rinse your clothes, dishes, skin, etc. soap free.

∙ 13y agoHere's a website with the experiement. I did it for a science fair project and got an A+. It's also really fun to do(: I used a lot of subsititutes from the experiment and I'd be happy to share my version, too.

How do you prepare soap solution for testing hardness of water?
titrate water with standard soap solution .End point is when floating bubbles aee stable
What are the two form of hardness found in water?
Hardness in water is usually characterised as temporary or permanent. Both are due to the presence of calcium or magnesium ions. If they are present as the hydrogen carbonate, when the water is boiled this is converted to the carbonate which precipitates out as a solid, leaving water which is no longer hard, so this is called temporary hardness. If they are present as the sulfate the solution is unaffected by boiling, and this is called permanent hardness.
How does adding soap to water affect adhesion?
Soap is a non-polar molecule that breaks weak hydrogen bonds between water molecules, so it makes the water less cohesive.
How does liquid soap affect the surface tension of water?
it affects the surface tension because of its temperture
Water hardness due to?
We often talk about water of different qualities in our daily life and very often we are faced with certain problems caused by hard water. The total hardness (TH) consists of all calcium (Ca) and magnesium (Mg) salts dissolved in it. Water hardness consists of two types of hardness, carbonate, and non-carbonate. Carbonate hardness consists of calcium and magnesium bicarbonates Ca(HCO3)2 and Mg(HCO3)2. Non-carbonate hardness consists of all their other salts such as chlorides, nitrates, sulfates, etc. After washing in hard water, stains from precipitated limescale remain which are very difficult to remove, textiles washed in “hard” water become stiff due to the deposition of limescale on fine textile fibers, and washing in hard water consumes more detergents due to the reaction of detergents with hardness salts and, creation of insoluble soaps – soap scum. Using soft water can solve all these problems.

What materials will you need for what affect does soap and water have on plants?
soap,water,plants
How does soap affect fats?
Soap dissolves fats and helps them become soluble in water.

What do you see when distilled water is added to washing soda crystals?
fully distilled water has no hardness therefore the soap will not lather
Does soap affect the buoyancy of water?
If it alters its density, yes.
What is the effect of soap and detergent in the hard water?
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.
When is the water soft?
when all or most of the ca2+ ions in the water have been replaced by na1+ ions meaning when soap foams in water. After removing hardness producing ions, the water may be soft.
What is the role of Coconut oil in soap?
Coconut is used in soap because of its hardness and moisturizing nature. It helps to make soap hard.
What is pseudo hardness?
pseudo hardness interferes to high concentration of sodium ion which interfers with normal behavior of soap.
How does soap affect oil?
Soap helps break up oil. This happens because the soap particles surround the oil molecules and help them dissolve in water.
How do you affect the river water by total hardness?
Water is polluted from sewage, industrial wastes, and wide array of synthetic chemicals. Pollution is the creation of wastes by man's activity and nature's inability to absorb it. Hard water is that has high mineral content (in contrast with soft water).Hard water has high concentrations of Ca2+ & Mg2+ ions . Hard water is generally not harmful to one's health but can pose serious problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers ,cooling towers ,other equipment that handles water. In domestic settings, the hardness of water is often indicated by the nonformation of suds when soap is agitated in the water sample.
