In the 17th century, Johann Rudolph Glauber made hydrochloric acid and sodium sulfate by reacting sulfuric acid and sodium chloride. With the event on the direct chamber process in 1746 as well as the Leblanc approach, making it possible for huge-scale manufacture of sulfuric acid and sodium carbonate, respectively, chemical reactions became implemented in to the business. Further optimization of sulfuric acid technology resulted during the Call approach during the 1880s,[six] and also the Haber method was developed in 1909–1910 for ammonia synthesis.[7]

Mixture reactions can be named synthesis reactions .The overall form of a combination reaction is:
