Organic Acids And Bases


Examples of these compounds include: lactic acid, acetic acid, formic acid, citric acid and oxalic acid.
Acetic acid, ethanoic acid or acetic acid is an organic acid chemical compounds known as sour flavoring and aroma in food. Acetic acid has the empirical formula C2H4O2. This formula is often written in the form of CH3-COOH, CH3COOH, or CH3CO2H. Pure acetic acid (called glacial acetic acid) is a colorless hygroscopic liquid, and has a freezing point of 16.7 ° C.
Acetic acid is one of the simplest carboxylic acids, as formic acid. Solution of acetic acid in water is a weak acid, meaning that only partially dissociate into H + and CH3COO-. Acetic acid is a chemical reagent and industrial raw materials is important. Acetic acid is used in the production of polymers such as polyethylene terephthalate, cellulose acetate and polyvinyl acetate, as well as a wide range of fibers and fabrics. In the food industry, acetic acid is used as an acidity regulator. In households, diluted acetic acid is often used as a water softener. Within a year, world demand for acetic acid to 6.5 million tons per year. 1.5 million tons per year generated from the recycling, the remainder derived from the petrochemical industry as well as from biological sources.
And further the organic bases of organic bases that we have encountered many in DNA and RNA da tone also those around us as ammonia
And organic bases in the DNA and RNA were also on the up again there purine bases pyrimidine bases da tone too.

  1. Vinegar is very beneficial to humans, but in addition there are several benefits of vinegar there are also negative effects that bias make it kropos or decayed teeth
    I ask why vinegar bias makes it kropos or decayed teeth, and we can find out together in the teeth that it also contained a lot of enamel and dentin why bias vinegar damage the enamel or dentin,

    1. I think that because he's so sour it makes our teeth can not stand and make it eroded emanel
      that if you ask me

    2. I'll try to answer
      Bacteria will process food waste in our mouth becomes acidic. (This process may be imagined like the food becomes stale, stale food will also sour right?)

      This acid will attack the teeth and make the teeth become brittle (a process of demineralization). Apart from this process, acids attack the teeth can also come directly from food / drink we consume, the process of tooth decay by direct acid is known as dental erosion. Below is a chart that shows the level of acidity of foods / drinks which we used daily consumption:

      Chart the acidity of food daily drink PH is good for dental health is pH neutral (in the range 6-7), the smaller the pH showed a higher degree of acidity (ie more acidic). Our mouth is critical pH 5.5, due to demineralization / tooth decay process begins at this pH.

      We can see that some of the food / beverage craze we are under a critical pH of the mouth, in the sense of can cause dental erosion became brittle teeth, the source of all dental problems

    3. habit of consuming foods containing high levels of acetic acid. This will lead to tooth loss is easy, because the vinegar will erode the phosphor coating on the teeth.
