Существует десять общих способов получения средних солей. Они основаны на химических свойствах важнейших классов неорганических соединений, а также простых веществ (металлов и неметаллов) . В таблице, отражающей генетическую связь между веществами, общие способы получения солей обозначены крестиками. Учтите, что не любой из этих способов применим для получения конкретной соли, обычно их число меньше десяти.
