In the above equation, the overall charge is zero, or neutral, on both sides of the equation. The cation is given the same name as the neutral me tal atom. Balancing by charge means making sure that the overall charge is the same on both sides of the equation. The charge on the cation is the same as the group number. Balancing by mass means ensuring that there are equal masses of each element on the product and reactant sides. Net ionic equations must be balanced by both mass and charge. However, it is not absolutely necessary to order the reactants in this way. This is somewhat customary because that is the order in which the ions must be written in the silver chloride product. Notice that in writing the net ionic equation, the positively-charged silver cation was written first on the reactant side, followed by the negatively-charged chloride anion. The internal sensing elements are housed within a durable.
The silver/silver sulfide sensing pellet produces a potential change due to the ion exchange between the inorganic pellet membrane and the sample. Because of the extreme insolubility of silver sulfide, the two ions are virtually never present in solution together. The net ionic equation is the chemical equation that shows only those elements, compounds, and ions that are directly involved in the chemical reaction. The HI4115 is a solid state, combination ion selective electrode (ISE) for the determination of silver (Ag +) or sulfide (S 2-) in solution. The Orion 94-16 Silver/Sulfide Half-Cell Electrode and Orion 96-16 Sure-Flow Combination Silver/Sulfide Electrode measure silver and sulfide ions in aqueous solutions quickly, simply, accurately, and economically.
