1 Do what you're comfortable with and tip if you like the service or don't tip if you feel tipping an owner is ridiculous. 2  Switch stylists to someone who doesn't own the salon.  Accept that tipping is customary and add it into the cost of the service. If you can't afford the tip, switch to a less expensive stylist.
Standard Electrode Potentials. In an electrochemical cell, an electric potential is created between two dissimilar metals. This potential is a measure of the energy per unit charge which is available from the oxidation/reduction reactions to drive the reaction. It is customary to visualize the cell reaction in terms of two half-reactions, an oxidation half-reaction and a reduction half-reaction.
Reduction at cathode. The cell potential (often called the electromotive force or emf) has a contribution from the anode which is a measure of its ability to lose electrons-it will be called its oxidation potential. The cathode has a contribution based on its ability to gain electeons, its reduction potential.ince the tabulated standard electrode potentials are reduction potentials, the one which is most negative will need to be reversed in sign to get its oxidation potential. When that is done, it is clear that the theoretical standard cell potential for the zinc-copper cell is 1.10 volts.
