Methylene blue active substances (MBAS) bring about the transfer of methylene blue, a cationic dye, from an aqueous solution into an immiscible organic liquid upon equilibration. This occurs through ion pair formation by the MBAS anion and the methylene blue cation. The intensity of the resulting blue color in the organic ...formalcharge(H) = 1 −(0 + 2 2) = 0. The formal charges on the atoms in the NH 4+ ion are thus. In the Lewis structure, each hydrogen has a zero placed nearby while the nitrogen has a +1 placed nearby. Adding together the formal charges on the atoms should give us the total charge on the molecule or ion.C + H2 + Cl2 = HCCl3 - Chemical Equation Balancer.
