PH-neutralization.xlsx

the neutralization reaction of a strong acid (HNO₃, q₁), a buffer stream (NaHCO₃, q₂) and a strong base (NaOH, q₃) in the reaction tank. The PH value of the output stream is measurable and determined by the flow rate of inlet (q₁~ q₃) and outlet (q₄). In order to keep a constant level in the tank, the flow rate of outlet stream varies with the inlets streams flow rate. A data set of 81 samples points was obtained under the conditions of different inlet flow rate to verify the relationship between the pH and the liquid flow q₁~q_4.
