Therefore in this example the manufacturers recommended weight of magnesium anodes would be 14kg to 20kg. Luckily anodes are sold by weight. Common sizes are 1.5kg, 2.5kg and 3.5kg ingots for standard weld-on canal boat anodes.nodes will offer protection based on the Noble Series of metals. The theory is that by attaching a piece of metal to the hull that is more reactive than the hull itself then this piece of metal will corrode first. For our inland waters we use sacrificial magnesium anodes for protection.
Pure water is a poor conductor of electricity while fresh water or tap water may be said to be a modest conductor and salt water has a much higher conductivity than fresh wate â¦ r. The electrical conductivity of water, both pure water and water with dissolved salts, is simpler to measure than to explain.
Pure water is not a good conductor of electricity. Some substances when dissolvedin water to produce a solution will conduct an electrical current. Such substances produce ions (charged electrical particles) when dissolved in water and these ions carry the current through the solution.his science fair project focuses on the use a conductivity device that will enable the investigator to determine if a substance dissolved in water can or cannot conduct electricity and if it can, what type of conductor (electrolyte) it is.
