The most common characteristic of bases is their bitter taste and soapy feel. A base is a substance that renders hydroxyl ion(OH–) in their aqueous solution. Bases turn the colour of red litmus paper to blue.
Salts
Salt is an ionic compound that results from the neutralization reaction of acids and bases. Salts are constituted of positively charged ions, known as cations, and negatively charged ions, known as anions, which can either be organic or inorganic in nature. These ions are present in a relative amount, thus rendering the nature of the salt neutral.
