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.

反应釜内发生强酸（硝酸，HNO₃，流量参数q₁）、缓冲液流（碳酸氢钠，NaHCO₃，流量参数q₂）与强碱（氢氧化钠，NaOH，流量参数q₃）的中和反应。出料流的pH值可被实时测量，其数值由各入口流股（q₁~q₃）与出口流股（q₄）的流量共同决定。为维持反应釜内液位恒定，出口流股的流量需随各入口流股的流量动态调节。本数据集共包含81个样本点，采集自不同入口流量工况下的实验数据，用于验证pH值与各流股流量q₁~q₄之间的关联关系。
