In chemistry a salt is any compound formed by the neutralisation of an acid by a base or an alkali. It does not just refer to table salt. Sodium chloride is the chemical name for common table salt.

The addition of NH 4 Cl to a solution of ammonia shows the effect of adding a common ion to a system at equilibrium.

Neutralisation is the reaction of an acid with a base that results in the pH moving towards seven. It is a useful process that occurs in everyday life such as in the treatment of acid indigestion ...

Pour desired household chemicals into separate 50 mL beakers. Add a few drops of universal indicator OR about 25 mL of red cabbage indicator and mix. Compare colors to standard solutions in lighted ...

A pH or acid-base indicator is a compound that changes color depending on the pH of the substance that is added to it. Acids and bases make pH indicators turn different colors. Two substances that ...

How can just four nitrogenous bases--adenine, cytosine, guanine, and uracil--possibly code for all 20 amino acids? Thus, early researchers quickly determined that the smallest combination of As ...

Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists ... two or three different bases.
