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.
Key Concepts. 1  A metal is a lattice of positive metal 'ions' in a 'sea' of delocalised electrons. 2  Metallic bonding refers to the interaction between the delocalised electrons and the metal nuclei. 3  The physical properties of metals are the result of the delocalisation of the electrons involved in metallic bonding.
