Soap is a fatty acid reaction product, after saponification, saponification fatty acid is a zwitterionic surfactant, a hydrophilic based on hydrophobic, hydrophilic ion adsorption in soapy water to the surface of the water-repellent based ion separation, the formation of groups like structure to form pull bubbles, liquid detergent and soap can be mixed. This is because these two materials are anionic detergent washing, but close to neutral liquid detergent and soap is alkaline. It is worth noting, however, soap soluble in water. If the wash water temperature is low, not only soap removal effect should be discounted, but not easy to rinse clean and drowned. To do this, use soap when washing clothes, preferably with some warm water.

1. Identification of hard water soap to improve tests

The stearic acid, sodium hydroxide (accounting for about 15% of stearic acid mass) into the beaker, add appropriate amount of ethanol as solvent. Slowly heating the mixture to the surface in the beaker without oil beads, or get soap. Two were added in the test tube containing a small amount of distilled water and calcium chloride solution, and then drops the soap, observed phenomena. Experimental results show that the new system of soapy water to test the effect of hard water is better than the muddy, soapy water, soap can eliminate the interference of other components, the phenomenon of apparent configuration of soapy water to facilitate easy operation, saving time and materials.

1. To do with soap colloid experiments

①     Tyndall phenomenon: the beam of light through the liquid soap from the side you can see a bright path.

②     ② salt (colloid coagulation): the liquid soap into a beaker containing saturated salt water, the beaker of liquid layers, namely the upper white solid soap (sodium stearate).

1. The cohesive effect of the use of soap manufacturing solid alcohol

Preparation of solid alcohol, can serve as a fun experiment, students in the event of chemical knowledge, enhance their interest to apply their knowledge. Use of soap (sodium stearate) as a coagulant, so that the liquid alcohol is included in the framework of its space in the mesh can be solid alcohol. 2.5g of solid sodium hydroxide will be added 150ml 95% ethanol solution, then add 10ml of water, that is, a liquid, can be divided into ten. The other will be 1.5g of sodium dissolved in 20ml 95% stearic acid in ethanol solution, obtained a B solution. The two solutions will be placed in two small beaker in a water bath heated to boiling, liquid B will stop all the heat into a fluid, slightly stirred, cooled after alcohol was a translucent solid.

Tide is the world’s leading Japanese-based P & G’s well-known detergent brand is the world’s first synthetic detergent washing powder is the most popular one in the United States, was born in the United States in 1946, is the world’s first synthetic detergent .
