If any of your boating is also in brackish or salt water, fit aluminum anodes. Don Casey has been one of the most consulted experts on boat care and upgrades for 30 years, and a panelist on our Ask The Experts website for a decade.here the zinc is mounted directly to the protected metal--bolted to the side of a metal rudder, for example--it is essential to make sure the surface under the zinc is bare and bright before the anode is installed. This is to ensure good electrical contact.
A hydrophobic molecule is a molecule that won't combine with water. The word hydrophobic describes this water-repelling characteristic; hydro means water in Greek, and phobic derives from phobos, which means fearing.. Though these molecules don't literally fear water, they do not mix with water molecules.
Now the molecule also has a bent shape, and angular shape, so that the molecule itself is a polar molecule. As a result, water is an excellent solvent for other polar molecules, particularly those which have hydrogen bonded to either oxygen or nitrogen atoms. This is because it is possible to have hydrogen bonding between the molecules. Water is also an excellent solvent for both positive and negatively charged ions. With a positively charged ion, water molecules can surround the ion with the negative oxygen end nearest the positive charge and with the negative ion, a water molecule can have its positively charged hydrogen end closest to the ion.
