BaSO 4: The precipitate of barium … WebThe titration’s end point is the formation of a reddish-brown precipitate of Ag 2 CrO 4. Note The Mohr method was first published in 1855 by Karl Friedrich Mohr. Because CrO 42– imparts a yellow color to the solution, which might obscure the end point, only a small amount of K 2 CrO 4 is added.
