... pH and logarithmic units The activity of hydrogen ions can be expressed most conveniently in logarithmic units. pH is defined as the negative logarithm of the activity of H+ ions: – pH = -log [H+] – where [H+] is the concentration of H+ ions in moles per liter (a mole is a unit of measurement, equa ...

HYDRATE EARLY, HYDRATE OFTEN!
... Prehydrate two hours prior to practice or competition with 16-20 ounces of fluids and another 8-10 ounces after warm-up. During exercise: Frequent water breaks, taking in 6-8 ounces every 15 -20 minutes during activity, will also prevent dehydration. When exercising for longer than 50 minutes, sport ...

Hard water
Hard water is water that has high mineral content (in contrast with ""soft water""). Hard water is formed when water percolates through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates. Hard drinking water may have moderate health benefits, but can pose serious problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of suds formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters. Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects.
