According to the neutralization reaction, the remaining value is calculated based on the concentration of hydrogen ions or hydroxide ions in the saline solution: pH = -LOG(hydrogen ion concentration) or pH = 14 + LOG(hydroxide ion concentration)

PH=14+log(concentration of hydroxide ions), as stated in high school chemistry textbooks
