Welcome To Whitehall Township Whitehall Township is located in the center of the Lehigh Valley. The Township is one hour north of Philadelphia and an hour and half from New York City.
SALINITY OVERVIEW Salinity is the concentration of dissolved salts in water, usually expressed in parts per thousand (ppt). Objects float higher in salt water than fresh water because salt water is denser (heavier per unit of volume).
NOTE: Parts per million (ppm) is a common concentration measure used in environmental chemistry. The formula for ppm is given by: Carbon dioxide reacts with water to form carbonic acid (Equation 1). Carbonic acid then dissociates to give the hydrogen ion (H +) and the hydrogen carbonate ion (HCO 3 -) (Equation 2).The ability of H 2 CO 3 to deliver H + is what classifies this molecule as an acid, thus lowering the pH of a solution.he formula for ppm is given by: Carbon dioxide reacts with water to form carbonic acid (Equation 1).
