Question

1. when is
a salt formed?​

Answer 1

Answer:

In terms of chemistry, a salt can be any compound formed by the reaction of an acid with a base. Energy, in the form of heat, is given off during this neutralization reaction so it is said to be exothermic. The most common salt, sodium chloride (NaCl), is a product of the reaction between hydrochloric acid (HCl) and the base sodium hydroxide (NaOH). In this reaction, positively charged hydrogen ions (H+) from the acid are attracted to negatively charged hydroxyl ions (OH-) from the base. These ions combine and form water. After the water forms, the sodium and chlorine ions remain dissolved and the acid and base are said to be neutralized. Solid salt is formed when the water evaporates and the negatively charged chlorine ions combine with the positively charged sodium ions.

Solid sodium chloride exists in the form of tiny, cube-shaped particles called crystals. These crystals are colorless, have a density of 2.165 g/cm3 and melt at 1,472°F (800.8°C). They also dissolve in water, separating into the component sodium and chlorine ions. This process known as ionization is important to many industrial chemical reactions.
