The wig heads, now in various states of decoration, are proving to be a big hit. Things can get pretty silly around here late at night. Fortunately, we do have water to drink. Salinity is the total amount of solid material that is dissolved in water. Actually, if you do that, you will only have one component of seawater.
Ocean water includes various salts, metals, and even dissolved gases.
They are chlorine, sodium, sulfur, magnesium calcium and potassium. Another 89 elements have been identified in seawater, but in extremely small amounts. There are various ways to measure the salinity of water. You can take a measured weight of seawater, let the water evaporate, and then weigh the salt which is left. This method is not the most accurate, although it works very well in the your kitchen or school laboratory.
