Acid

An acid is a substance which dissociates in water to give positively charged hydrogen (H+). Acids are generally sour in taste and react with the base to produce salt. This note contains further information about acid, its chemical and physical properties. Learn More

Bases

A base is defined as any substance which releases hydroxyl ions (OH-) when dissolved in water. Bases which are soluble in water are called alkalies. This note about bases provides information about bases its properties and common uses. Learn More

Salt

A salt is a compound formed by the partial or complete neutralization of an acid by a base. Basic properties of salt include its salty or bitter taste, solubility in water and its unique coloration. This note provides information about properties, preparation, uses of salts. Learn More

Indicators

An indicator is a substance which changes color in the presence of acids or alkalis. The pH scale is a standard scale, which is used for measuring the approximate strength of an acid or an alkali solution. This note provides an information about the indicator, its type and features. Learn More
