Soap without white coloring substance, the color is white pale, the color is like light ivory color. We use a few drops of food coloring in the final stage.

Soap-making recipes contained in the book of Nelson Chemistry 12, that published by Nelson Thomson in 2001, edition of Ontario (Canada).

As what I know, the soap started to attract human attention when people see the form of bubbles when rain falls on the dust where they want to cook meat outside their house, like camping. The bubbles turned out to be very effective in cleaning grease, much better than only using water. In fact, soap is formulated when animal fat is heated by dust that have strong base.

Solvents that change their hydrophilicity on the addition and removal of CO2 can eliminate the need to make energy-intensive distillation on an industrial scale.

In the chemical processing industry, the separation of solvent from the product is usually done by distillation and requires the addition of a volatile solvent and a very large amount of energy. Today, Philip Jessop and his colleagues at Queen's University in Kingston, Canada has developed a new type of solvent that can change from hydrophobic into hydrophilic which means can be moved from its product without distillation.

A professor who is not known, which is studying the organisms attached to, willing to answer the question above.

Therefore pottery made of clay burning in the oven; I thought that the hydrochloric acid cannot destroy the pottery.

As you know, hydrochloric acid is stored in glass bottles. Glass is an amorphous silicate (silica), and the main components of clay are also silica. In addition, the substance coating for pottery is also classified as glass. Therefore, if the immersion time is relatively short, I think it is a good idea to use diluted hydrochloric acid to clean the pottery material.

Chemistry is the science of material, nature, structure, reaction and energy that accompanies the changes. Chemical specially divided into several main areas, namely: analytical chemistry, organic chemistry, inorganic chemistry, physical chemistry, and biochemistry.

Chemical is assessing the nature of substances, and in particular studying the reactions that transform one substance into another substance. Chemistry provides the guidelines to adjust the needs of substances that exist to meet some specific need or application and create a material that is really new, designed from the outset in order to have certain desired character of material. Through all the success, the chemistry has contributed to remarkable improvements in agricultural products, controlling the spread of disease, increase energy production, and reduction of environmental pollution.
