Concentration units for the elements involved are all in mg/L. The empirical coefficient value is determined based on the calculation result. When the calculated temperature is less than 100°C, the empirical coefficient is 4/3; when the calculated temperature is higher than 100°C, the empirical coefficient is 1/3.
