Document Summary
70. 8% of the earth is covered by water. An ion is an atom or molecule where the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge. Intermolecular bond of hydrogen with an electronegative atom. 105 degrees apart in the water molecule. *hydrogen bonds are weak* - only between 2 water molecules. Covalent bonds between oxygen and hydrogen molecules are strong (within water molecules) Positive on one end, negative on another. The total amount of solid material dissolved in water (not including dissolved organic substances); it is the ratio of the mass of dissolved substances to the mass of the water sample. Does not include fine particles in suspension. Oceanic salinity is based on the balance between input and output of ions. Salinity is expressed in parts per thousand (ppt) Parts of salt per thousand of seawater.
