The composition of salt water, or sea water, is about 35 parts of salts per 1,000 parts of fresh water, though the salinity can vary from between 30 to 37 parts per 1,000. The salts are mostly sodium and chloride, the sa... More »

The chemical composition of table salt is NaCl. Table salt is a combination of sodium and chlorine, which form ionic bonds. More »

The chemical composition of table salt is one atom of sodium (Na) to one atom of chlorine (Cl), known as sodium chloride (NaCl). Table salt also often has iodine added in for health reasons, but this does not change the ... More » Science Chemistry Atoms & Molecules

The time it takes for salt water to freeze depends on the amount of salt in the water, the temperature of the water, and the volume of water. The more salt the water has, the lower its freezing point. Smaller volumes of ... More »

Some recipes for growing crystals include mixing three tablespoons of borax with a cup of boiling water or mixing equal parts Epsom salt and hot tap water. Salt crystal geode recipes call for only hot water, salt and an ... More » Science Chemistry

Rock salt, solar salt or evaporated salt are the primary salts used in water softeners and are all primarily sodium chloride. Solar salt, made by evaporating seawater, has the lowest sodium chloride levels at 85 percent.... More »

An ocean's salinity is affected by water and air temperature, the volume of water that flows into it, its age and the chemical composition of surrounding geological formations. Because the effect of these factors varies ... More »
