Determination of Calcium Ion Concentration
www.canterbury.ac.nzthe concentration in mol L−1 of Ca2+ in your sample solution. 4. Calculate the concentration, in mg/L (parts per million or ppm), of Ca2+ in your sample solution. 5. In the case of a solid sample which has been dissolved in acid, the concentration of Ca2+ in your sample solution may be used to calculate the percentage, by weight, of CaCO 3
Manual: Theory and Practice of pH Measurement
www.emerson.comTherefore, if the hydrogen ion concentration is 1.0 x 10-4 moles/liter, the pH is 4.00. The term neutral is often used in discussions about acids, bases, and pH. A neutral solution is one in which the hydrogen ion concentration exactly equals the hydroxide ion concentration. At 25°C, a neutral solution has pH 7.00.
Precipitation Titration: Determination of Chloride by the ...
academic.brooklyn.cuny.eduStandard silver nitrate solution and the silver chloride precipitates formed were protected from light at all times because silver chloride decomposes according to: AgCl ÷ Ag(s) + ½ Cl 2 (g) The silver ion concentration at chemical equivalence in the titration of chloride with silver ions is given by: [Ag+-] = = = 1.35 x 105 M
