Question

Name the acid present in vinegar.

Answer 1

An acid is any compound which contains hydrogen that has the power of donating a proton (hydrogen ion) to a different compound.

Complete step by step answer:
Acid bases and salts find widespread occurrence in nature. The acid present within the digestive juice is secreted by the liner of our stomach in a very significant amount of $1.2-1.5 L$ each day and is crucial for digestive processes. ethanoic acid is understood to be the most constituent of vinegar. Lemon and orange juices contain citric and ascorbic acids, and hydroxy acid is found in tamarind paste.. Acids are known to show blue paper into red and liberate hydrogen on reacting with active metals. Similarly, bases are known to show red paper blue, taste bitter and feel soapy. A standard example of a base is salt used for laundry purposes. When acids and bases are mixed within the right proportion they react with one another to offer salts. Some commonly known samples of salts are common salt, barium sulphate, soda niter etc. common salt (common salt) is a vital component of our diet and is created by reaction between acid and caustic soda. It exists in solid state as a cluster of charged sodium ions and charged chloride ions which are held together because of electrostatic interactions between oppositely charged species. The electrostatic forces between two charges are inversely proportional to the dielectric constant of the medium. Water, a dissolvent, possesses a really high dielectric constant of $80$. Thus, when a binary compound is dissolved in water, the electrostatic interactions are reduced by an element of 80 and this facilitates the ions to maneuver freely within the solution. Also, they're well-separated because of hydration with water molecules.
Comparing, the ionization of acid thereupon of ethanoic acid in water we discover that though both of them are polar covalent molecules, former is totally ionized into its constituent ions, while the latter is barely partially ionized ($<5\%$). The extent to which ionization occurs depends upon the strength of the bond and also the extent of solvation of ions produced. The terms dissociation and ionization are used with different meanings. Dissociation refers to the method of separation of ions in water already existing in and of itself within the solid state of the solute, as in common salt. On the opposite hand, ionization corresponds to a process within which a neutral molecule splits into charged ions within the solution. Here, we shall not distinguish between the 2 and use the 2 terms interchangeably.

Acid present in vinegar is ethanoic acid.

Note: Acetic acid is present in $5-20\%$ by volume in vinegar. Formula of carboxylic acid is $C{{H}_{3}}COOH$. Vinegar is mainly used for cooking purposes.
