Which one's pH's value is higher- soap, or hand sanitizer's?

Most hand sanitizers use alcohol as a sterilant, so unless there's something in them to make them more alkaline, the pH should be pretty close to neutral -- 7.  That would mean that soaps have the higher pH.

Definitely.  When I have mechanic's hands, I sometimes have used Tide to clean my  hands.  It is much stronger and more drying thant hand soap.  Dishsoap has the capability to emulsify dirt better than regular soap.  I see this when I put the barbque rack in the sink and wash it with Dawn.  The foam traps all the little burnt peices of meat and keeps it out of the water during the washing.

think about how many people use a restroom everyday, then think about how many wash their hand properly, [like none, you have to wash ur hands for at least a minute] so imagine how bacterial feces and vaginal blood and all that. i don't even want to think about it. i just bring hand sanitizer everywhere.

Keep the chlorine level at 1.5 ppm and shock regularly and it is not a problem. It is, however, not socially acceptable. But no one is going to get a disease from it-- IF the chemicals are maintained properly. We "carry" a lot of foreign matter into a pool when we go in. Saliva, dead skin, hair, dandruff, etc., etc. That's why pool sanitizers are necessary! Plus, a pool being an open vessel, is constantly bombarded with air borne contamination. Rain water does infinately more damage to a pool than a little urine.

more soluble in what solution?

Question is how many wash their hands after using toilet???\n\nDryer is cost less per use while paper towel does better job.

No need to break it down to "molecular" other wise, try this: Sodium thiosulphate. Dont just use it coz they all vary in their Ph U know the basisity or acidity they concentrate.

Actually, acid medium is a way to avoid fungal overgrowth, so i'd go with neutral or slightly alkaline

I'll answer the last part of your question first. Soap is made up of polar molecules. That just means that one end of each molecule is different from the other like the poles of a magnet. One end dissolves in grease and fats while the other end dissolves in water. Since most really dirty things are fatty and greasy, this means that one end of each soap molecule sticks to the dirt on your hands while the other end sticks to the water running over them. This washes the dirt away. Why not use plain water? If you don't have soap plain water will help get you clean but because of surface tension water won't stick to grease so you will never get completely clean. Another class of cleaners solves this problem. Detergents reduce the surface tension of water allowing it to clean better. Look at the list of ingredients on your cleanser. If one of them is Sodium Lauryl Sulfate, your cleanser is a detergent. Now for the first part of your question. Long ago people found that you could make a cleaner by heating lard (renderings from animals killed for food) with potash, an alkali produced by burning wood, probably for cooking the aforementioned food. This discovery was probably accidental, the result of being in the right place at the right time. It took place so long ago that the discoverer (or discoverers, it probably happened in several places at different times) is lost in history. BTW. It's no coincidence that many of today's soap producers are owned by or connected to slaughter houses and meat producers. Do some research on Procter and Gamble. Your teacher will be proud of you.

Sodium hydroxide is a very strong base, not an acid (the common name is lye).\nTriglycerides are fats, like beef tallow.  Mixing them and allowinging to react would produce Granny's lye soap.

Antibacterial cleaners main ingredient is alcohol. The alcohol kills bacteria so it cannot spread to others. It does not remove it from your hands, just kills it. When you wash your hands you also wash away the dead bacteria.

98 % is but there r also air born diseases and viruses that r caught not by touch but from the air.If someone ate in a room with someone who had an airborn virus you would get it.I know this from experience.Hand sanitizer is good to take anywhere especially buses and when handleing money.

None.....soap scum is a chemical reaction.\n\nMold is the most common thing you find in the shower.\n\nBleach will destroy both of these.

Soaps are water-soluble sodium or potassium salts of fatty acids.Saponification of fats and oils is the most widely used soapmaking process.\nDetergent surfactants are made from a variety of petrochemicals (derived from petroleum) and/or oleochemicals (derived from fats and oils). \n\nCheck these links to find more information On Soaps & detergents to help your chemistry Project.

If you are working in a chemical lab, you should have gotten this answer during your safety training.  However, in the case of most strong acids (HCl, HBr, HI, H2SO4, etc.) you should flush with lots of water.  If irritation persists, you should seek medical attention promptly bring with you the MSDS for the chemical you spill on yourself.  If you spilled HF, you are in deep trouble.  However, I doubt you could have gotten access to HF without knowing the appropriate precautions to take.\n\nMedically, some acids are used in the removal of warts (among them is trichloroacetic acid).  The alternative there is freezing them off with liquid nitrogen.

my husband uses baking soda and water. \n\nI use a little bleach water with a VERY SMALL amount of dish soap and then rinse it all very well. Bleach is the same thing in city water, it wont hurt you, and it doesnt taste so horribly bad after its been rinsed out, where as baking soda does.\n\nwe're never tried it but we've heard that denture cleaner can work too.
