ABSTRACT The average concentration of CaCO3 obtained was 212 ppm‚ with a standard deviation of 1 ppt. The results indicate that the unk B tap water can be considered as hard water. INTRODUCTION Hard water is due to metal ions (minerals) that are dissolved in the ground water. These minerals include Ca 2+‚ Mg2+‚ Fe3+‚ SO42-‚ HCO3-. When this water evaporates or boils‚ the difficult to dissolve metal salts remain as a scaly residue. Hard water inhibits the effectiveness of soap and detergents

mixing by currents‚ winds‚ and tides. Other chemical and physical factors – such as salinity‚ pH‚ and especially temperature- can affect the dissolved oxygen (DO) concentration and distribution. Salinity‚ usually expressed as parts per thousand (ppt)‚ is the content of dissolved salts in water. Generally‚ as temperature and salinity increase‚ the solubility of oxygen in water decreases. The partial pressure of oxygen in the air above the water affects the amount of DO in the water. Less oxygen
