knowing that soap makes water loose stability, does it also make it thinner?

Water has (relatively) high cohesion, due to the polar covalent bonding of the water molecule. Soap destroys this covalency by adhering to water molecules with its ionic end. This is why soap is used as a cleanser. Soap itself doesn't clean, it disperses water molecules, thus increasing water's absorption properties. Without water's cohesive ability, items that float on the surface of water now sink.

Surface tension and elasticity of the water are just about the same thing, for all practical purposes. The water can not get out of the way fast enough to let the stone sink before the motion and deflection cause the stone to bounce. The gyroscope motion of the stone is what gives it enough balance to not lose much of it's momentum when it hits something, like water. That's why flat, smooth stone work best.

I'm quite sure that it does since bar soap has touched your body. It also probably collects bacteria from the air. Actually, pretty much everything has bacteria on it.

Ya you should cuz distilled water is not good as a conductor but adding salt to it makes it a good conductor of electricity and since soap contains alot of salts that can decompose into negative and positive charges i think ya u should worry about electric shock

The difference in solubility of the components allows for separation.  I don't remember the specifics, but that is the reason.  Water will not have a big enough difference.

shower gel all the way, soap dries out the skin sometimes, shower gel gives you some moisture.  Also, for me, it lathers up more easily, more fun in the shower!

The ethanol or alcohol is less polar that water and the fat that is being hydolyzed from its parent triglycerides is not soluble in water to any great degree. This is true if you are discussing the determination of free fatty acids in a fat or an oil. If you simply wish to make soap from fat, the base, water and fat will do a nice job of it but it will require additional sodium ion, usually in the form of salt to curdle the soap base.\n\nI learned to make soap for washing purposes with a recipe that started with: "First one must select a nice fat pig to kill...."

Not really it tends to make you lean with lots of endurance.  The resistance of water doesn't change.  However, if you see the pools where you stand up and fight the water.  Those can make people real strong.

Yes!!!!!! Because you stretch the arms and it elongates them, eventually making them thinner.

The problem is not the weight of the water, it's the drag of the fluid. Unless you can find some magic way to eliminate the drag in a fluid like water which is so much more than that of a gas, you will be stuck with lower speeds. Even if you had some "magic" bubble around the sub, you would still need to displace the liquid to move the bubble.

Normally, the soap we used is sodium or potassium salt made from the mixture of a sodium or potassium solution with fat acid.  Therefore, sodium palmitate, for example, is a salt and also a soap we used daily.  When sodium palmitate is dissolved by water, it will ionize into sodium ion and palmitate ion.  Palmitate ion is made out of two parts which is the hydrophobic part and the hydrophilic part.  The hydrophobic part will dissolves in grease or oil but not water, while the hydrophilic part will dissolve in water but not grease or oil.  In short, the hydrophobic part of the ion dislikes water while the hydrophilic part of the ion likes water.  Therefore, the hydrophilic part of the palmitate ion will dissolve in water, reducing or breaking the surface tension of water as the hydrophilic part of the ion forces itself into the neat structure of the water.  Therefore, the neat structure of the water will be broken up, causing the surface tension of water to break up.  For your information, palmitate ion is the one doing all the cleaning, breaking up the dirt on our clothes.  As for detergent, it ionizes into sulfonate ion and has two parts as well.  The mechanism of detergent breaking the surface tension of water is the same as the mechanism of soap.  I hope you understand what I’m saying as I learn all these in a different language.  Sorry if I wrote the wrong terms.

It's bernoulli's principle. Fluids have a lower pressure when moving than when still. Since the water is moving past the spoons (which act like the wing of a plane) they feel a pull from the pressure drop and come together. Try it with a peice of paper sometime. Roll a piec of paper up so when you place it on a flat surface it looks like a curved bridge. then blow under it and it will collapse instead of blow away. It's pretty neet.

Dont drop the soap! nite nite, keep your butt hole tight!

When you softly place a pin onto the surface of water (horizontally) it doesn't sink because the weight of the pin is balanced by the upward (vertical) component of surface tension. When you add a detergent powder it reduces the viscosity of water and hence the upward force due to vertical component of surface tenbsion decreases and hence it sinks.

a) Sodium stearate, a soap, forms a scum on bath tubs and shower screens with either magnesium, calcium or iron(II), as these salts are insoluble. For example:\n\n2CH3(CH2)16COONa  +  Mg^2+  ---> (CH3(CH2)16COO)2Mg  + 2Na^+\n\nb) Adding dilute HCl acid to soap, produces a greasy solid, which has its uses in cosmetics:\n\nCH3(CH2)16COONa  +  HCl  --->  CH3(CH2)16COOH  +  NaCl\n\nI hope that helps. If you need more assistance, please email me or re post.

they dont have large enough hydrophobic regions to absorb oils and greases into solution, or create micelles. the best soaps are Sodium fatty acids... they have an ionic side, which helps them be soluble in water, and a long organic chain to create a hydrophobic region to make it easier to form micelles in water to pick up grease.

water with salt bcoz water bcoms lighter wen alt dissolves in it ans hence its density decreases allowing it to evaporate easily
