acid. Refer to the matter as a sculptor with a common base reaction. Sour taste can be identified by acid, The reaction is made completely of metal properties, calcium and sodium carbonate, bass. Water soluble acid has a pH less than 7 are acidic, without force, based on the reduced pH values and change the blue litmus is red
.Ph value is a value that represents the value of a pH acid-base of the substance contained in the product by the value pH is in the range 1-14 pH values less than 7 the substance will be that type of activity is over 7 acids and pH values the substance of that type will have a formidable force as a base, or alkali. The pH is equal to 7 shows that the substance of that type in a neutral pH balance, also known as or is not acid or base does not cause skin irritations. The pH in the many useful substances in the manufacture of various products. Drinks ranging from cosmetics to medical industry. Agriculture etc
