    What is Indigestion and Acidity and How it is Caused?

    Acidity is nothing but excess secretion of gastric acid which is formed in our stomach to help us digest food. Secreted by special cells that line our stomach, this acid consists of hydrochloric acid, sodium chloride and potassium chloride. The main role of the gastric acid is to activate the various digestive enzymes in our stomach which help in breaking down the amino acids present in food particles.

    During an acid reflux, the gastric acid comes up through the food pipe due to over-production or improper closing of the 'lower esophageal sphincter' muscle. The LES works like a valve between our food pipe and stomach, preventing food that has passed from coming back up. When acidity occur, the LES does not work as it should and allows acid to enter the esophagus, thus causing mild to severe irritation and chest pain.

    What is tourine

    Taurine, or 2-aminoethanesulfonic acid, is an organic acid widely distributed in animal tissues. It is a major constituent of bile and can be found in the large intestine and accounts for up to 0.1% of total human body weight.[1] Taurine has many fundamental biological roles such as conjugation of bile acids, antioxidation, osmoregulation, membrane stabilization and modulation of calcium signaling. It is essential for cardiovascular function, and development and function of skeletal muscle, the retina and the central nervous system. Taurine is unusual among biological molecules in being a sulfonic acid, while the vast majority of biologically occurring acids contain the more weakly acidic carboxyl group. While taurine is sometimes called an amino acid, and indeed is an acid containing an amino group, it is not an amino acid in the usual biochemical meaning of the term, which refers to compounds containing both an amino and a carboxyl group.

    How carboxylic acid different from mineral acid from ionization point of view

    • A mineral acid is defined as a water-soluble acid derived from inorganic minerals by chemical reaction as opposed to organic acids (e.g. acetic acid, formic acid).
    • Specifically: When you put sulfuric acid (H2SO4) into water, all of the molecules of acid will dissociate into two protons (H+) and sulfate anions (SO4 -2). There will be no intact molecules of H2SO4 in solution. When you put acetic acid (CH3COOH) into water, only some of the molecules dissociate into proton (H+) and acetate anions (CH3COO-). Some of the acetic acid molecules remain intact in solution.
    1. - Mineral acids are inorganic derivatives while carboxylic acid is a organic compound.
    2. - Mineral acids dissociate completely into ions while carboxylic acid dissociate partially.
    3. - Mineral acids show high conductivity while carboxylic acid shows low conductivity.
    4. - Mineral acids shows negligible in ionization on increasing the temperature while ionization of carboxylic acid increases with the increase of temperature.

    Dose Muriatic Acid damage Chrome

    muriatic acid aka hydrocloric acid will attack chrome plating. (Pretty safe on Google Chrome though ;-]) If you are thinking about chromed pool fittings those are pretty safe as the ph in pools is pretty nuetral even after shocking a pool.

    If you are talking about the acid undiluted on chrome it will atack it but that will depend on the chrome, the acid strength and how long it is left on. Some people do use the acid to clean the chrome but wash off the acid right away with lots of water.

    I need to acid wash my grids. What is the ratio for acid and water?

    Why not try white vinegar and water first, 50/50 mix. White vinegar is a mild acid, and it is a lot safer to use than acid. If you are going to use Muriatic acid ( "mild" version of Hydrochloric acid), then a good ratio is 1 part acid to 20 parts water. And Always add the acid to the water. You could make a stronger solution, 1part acid to 10 parts water, if needed. But be cautious with any ratio. Follow container directions. Wear eye protection ( an absolute must). Wear gloves, etc. This is dangerous stuff, and you can buy it at Home Depot or Lowes!
