The electrical conductivity of sodium chloride NaCl in water depends on the concentration of the salt and the temperature of the solution. When NaCl dissolves in water, it dissociates into sodium Na+ and chloride Cl- ions, which are responsible for the conductivity of the solution. As the concentration of NaCl increases, the number of ions in the solution also increases, leading to higher conductivity. Similarly, as the temperature of the solution increases, the mobility of the ions also increases, resulting in higher conductivity.To provide specific values for the electrical conductivity of NaCl in water at various concentrations and temperatures, we can refer to the literature or experimental data. One such source is the "International Critical Tables of Numerical Data, Physics, Chemistry and Technology" by Washburn 1926-1930 , which provides the following values for the electrical conductivity k of NaCl solutions at 25C:- 0.01 mol/L NaCl: k = 1.09 mS/cm- 0.1 mol/L NaCl: k = 10.8 mS/cm- 1 mol/L NaCl: k = 76.7 mS/cm- 5 mol/L NaCl: k = 186 mS/cmAs for the effect of temperature on the conductivity of NaCl solutions, the conductivity generally increases with increasing temperature. For example, the conductivity of a 1 mol/L NaCl solution increases from 76.7 mS/cm at 25C to approximately 126 mS/cm at 50C and 182 mS/cm at 75C.In summary, the electrical conductivity of sodium chloride in water increases with both the concentration of the salt and the temperature of the solution. The exact values for conductivity at various concentrations and temperatures can be found in the literature or determined experimentally.
