WebSimply, plug the DO tip into the electrode body to perform calibration and measurement and unplug it when the DO electrode will be stored for a long period. Materials Needed Clean water (e.g., distilled, deionized, or tap water) Sodium sulfite (Na 2 SO 3) or Nitrogen gas Cobalt (II) salt (e.g., CoCl 2 •6H2O) Soft cotton gauze or tissue WebSalinity is the measure of the amount of dissolved salts in water. It is usually expressed in parts per thousand (ppt) or percentage (%). Freshwater from rivers has a salinity value of 0.5ppt or less. Within the estuary, salinity levels are referred to as oligohaline (0.5-5.0 ppt), mesohaline (5.0-18.0 ppt), or polyhaline (18.0-30.0 ppt).
WebThe electric potential of the S.H.E. is defined as 0 mV at 25℃ by such organizations as the International Union of Pure and Applied Chemistry (IUPAC). An S.H.E. is formed by dipping a platinized electrode into the hydrochloric acid obtained by bubbling saturation of hydrogen gas at 1 atm, giving a mean activity of 1 (approximately 1.2-N HCl). WebApr 14, 2024 · 3.4 Reference electrode. The electrode provides a constant potential independent of the pH of the measured medium (3.2). ノート 1: 現在, the most commonly used type is the silver/silver chloride reference electrode, whose potential is stabilized by a constant concentration of potassium chloride (KCl) (3.6) in the reference electrolyte. …
WebThe pH electrode behaviour follows the Nernst equation: E = E0 + 2.303 (RT/nF) log aH+ where slope, also called sensitivity, is denoted by -2.303 RT/nF and pH is equal to -log aH+. Since R, F, and n are constants, the slope changes with temperature and this effect can be compensated by a pH meter with ATC capability. Click image to enlarge.
