WebA complete reaction is one where all of at least one of the available reactants is used up and converted into products. So for example K C l and N a X 2 S O X 4: In this equation you will need 2 M K C l and 1 M N a X 2 S O X 4 in order for all the reactants to react. However, you only have 1 M K C l (so 1 M chloride ions). WebShekhar Suman. The difference in potential between two half cells in an electrochemical cell is called the cell potential, Ecell. The potential difference is caused by the ability of electrons to flow from one-half of the cell to the other. Electrons can move between electrodes because the chemical reaction is a redox reaction.
WebThese ions are known as spectator ions. Na+ + Cl– + Ag+ + NO3– → AgCl (s) + Na+ + NO3–. The spectator ions do not participate in chemical reactions. They present in the same form throughout the reaction. Their role is only to spector the chemical reaction. While writing net ionic equations the spectator ions are omitted from the ...
