As for other thermodynamic quantities, the standard cell potential, Ecell, is a cell potential measured when both half-cells are under standard-state conditions (1 M concentrations, 1 bar pressures, 298 K): To simplify the collection and sharing of potential data for half-reactions, the scientific community has designated one particular half-cell to serve as a universal reference for cell potential measurements, assigning it a potential of exactly 0 V. This half-cell is the standard hydrogen electrode (SHE) and it is based on half-reaction below: A typical SHE contains an inert platinum electrode immersed in precisely 1 M aqueous H+ and a stream of bubbling H2 gas at 1 bar pressure, all maintained at a temperature of 298 K (see Figure 17.5). Conversions Between Moles and Mass The molar mass of any substance is the mass in grams of one mole of representative particles of that substance. A balanced chemical equation is analogous to a recipe for chocolate chip cookies. ratio and rewrite the equation using the whole number ratio.
