(PDF) CHE485 - Lab Report on Preparation of Soap and ...

Soap produce precipitate if in contact with acidic water or hardness in water such as Ca2+, Mg2+ and Fe3+ ion as in the experiment but not the case for detergent. The hydrochloric acid needed to change the pH of the soap solutions to 3 is 10 drops of HCl while for detergent solution is 2 drops of HCl.

Cleaning Capacity of Soap with Hard and Soft Water (Theory ...

Although soap is a good cleaning agent, its cleaning capacity is reduced when used in hard water. Hardness of water is due to the presence of sulphates, chlorides or bicarbonate salts of Ca2+ or Mg2+ ions. Soaps are sodium or potassium salts of long chain fatty acids. When soap is added to hard water, the Ca2+ and Mg2+ ions present in hard ...

Science Story Time Experiment: Pepper Soap | Penn State ...

Stick your soapy finger into the water. The Science Behind It. The pepper floats on the water because it is less dense or lighter than the water. Remember the pepper is representing our germs in this experiment. Without any soap on your finger the germs (or pepper) don’t move at all. However, germs do not like soap.

Colors on the Move - American Chemical Society

The milk is made mostly of water molecules, but it also has fat molecules and protein molecules which are bigger than water molecules. The detergent is made up of detergent molecules. The cool thing about the different molecules is that they have positive and negative charges in different areas. Some molecules or parts of molecules have no charges.

Soap is the salt of a weak acid. Most organic acids arc weak acids. Consequently, hydrolysis occurs to some extent when soap dissolves in water. Soap solutions tend to be slightly alkaline (basic) due to partial hydrolysis of the acid. For part 2.4.1 Soap preparation at the end of this experiment, total soap produced is 3.1020g.

Dish Soap Bubbles Experiment | 3M Science at Home

Use a rubber band to fasten the towel to the open side of the bottle. Add the water and dish soap to the small bowl. Swirl to stir. Add food coloring directly to the towel. Get creative here – try to make a fun pattern! Dip the towel into the soap solution. Blow with force into the mouthpiece of the plastic bottle.

The detergent molecules also help to make the washing process more effective by reducing the surface tension of the water. Surface tension is the force which helps a blob of water on a surface hold its shape and not spread out. The surfactant molecules of the detergent break apart these forces and make water behave, well, wetter! Back to the top.
