In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases and Lewis bases.All definitions agree that bases are substances which react with acids as originally proposed by G.-F. Rouelle in the mid-18th century.. Svante Arrhenius proposed in 1884 that a base is a substance which dissociates in aqueous solution to form hydroxide ions OH −. Following the basic hydrolysis, we added a small volume of highly concentrated (5x) acetate/acetic acid buffer with pH about 4 to our basic hydrolysate and adjusted the pH using 6 M HCl. Top Pick!
