A chemical compound is a pure chemical substance consisting of two or more different chemical elements[1][2][3] that can be separated into simpler substances by chemical reactions[4] and that have a unique and defined chemical structure. Chemical compounds consist of a fixed ratio of atoms[3] that are hold together in a defined spatial arrangement by chemical bonds. [Wikipedia]
A salt is defined as the product formed from the neutralization reaction of acids and bases. Salts are ionic compounds composed of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). [Wikipedia]
