<span>Cell references in a formula are called electrode potentials. Electrode potentials are standard voltages for half-cell potentials. All half-cell potentials use the Standard Hydrogen Electrode (SHE) as a universal reference for redox reactions. For hydrogen, the standard electrode potential is zero for all temperatures.</span>
Answer:
When dissolved in water, acids donate hydrogen ions (H+). Hydrogen ions are hydrogen atoms that have lost an electron and now have just a proton, giving them a positive electrical charge. Bases, on the other hand, mixed with water yield hydroxide ions (OH-).
Element which possess different number of "Neutrons" in different situations could be an isotope of the atom
Ex. - 17 Cl 34, 17 Cl 35, 17 Cl 36
They all the isotopes.
