Acid Bases Organik

         The purpose of the organic acid is a weak acid is very incomplete because of ionization. At one time most of the acid in solution as molecules that are not ionized. For example, in the case etanoik acid, a solution containing 99% etanoik acid molecules and only 1 percent of that is really ionized. The position of the equilibrium being shifted to the left.
Comparing the strength of a weak acid
The strength of weak acids measured by pKa scale. The smaller the stronger the acidity level.
Factors to be considered
Two factors that affect the ionization of the acid is:
• The strength of the bond to be decided,
• the stability of the ions formed
The organic acid is a carboxylic acid group and is an organic base is an amine compound group.
- Carboxylic Acid
    Carboxylic acids are organic acids characterized by the carboxyl functional groups formed through the combination of a carbonyl group with a hydroxyl group in a carbon trail.
Carboxylic acid derivatives are esters, carboxylic acid anhydrides, and amides.
- Extraction of acid-base: based on the acid-base properties of organic compounds in addition kelarutanya.
Preparation of Carboxylic Acid Esters Using
This method can be used to convert alcohols into esters, but this method is not applicable to phenols - compounds in which the-OH group is attached directly to a benzene ring.
- The chemistry of the reaction
Esters are produced when carboxylic acid is heated with alcohol in the presence of acid. The catalyst is usually concentrated sulfuric acid. Dry hydrogen chloride gas is sometimes used, but their use tends to involve aromatic esters (carboxylic acid ester which contains a benzene ring).

  1. As we know that the example of the organic acid is a carboxylic acid. We can create instances of such carboxylic acid esters, carboxylic acid anhydrides, and amides. Is the derivative of a carboxylic acid is also acidic? If yes, is the strength of the acid derivative of the first acid decreasing or increasing? Is organic acids can be converted into an inorganic acid or vice versa?

  2. I will try to answer. yes derivative is also acidic, but it seems to diminish the degree of acidity. I know of inorganic materials can be converted into organic materials such as organic mercury Derived from Inorganic mercury which is then converted into methyl mercury by bacteria in the sediment and the water is acidic.
    but for a change from organic to inorganic I know less

  3. based on what I know about the conversion of inorganic compounds to ogranik. Urea is an organic compound composed of the elements carbon, hydrogen, oxygen and nitrogen with CON2H4Senyawa this formula are organic compounds made ​​the first successful synthesis of inorganic compounds, which ultimately undermine the concept of vitalism.

  4. In my opinion the derivative carboksilat chemistry still have same acidic charecteristic, because the the structure is still same, contain of H+, but it has lower acid characteristic.
