Abstract:
Hydrochloric acid in chemical industries such as oil well acidification steel pickling, food production, ore and calcium chloride processing, to name but a few, is a commonly used chemical product. Consequently, as an entity that demonstrates various activities at various levels of pH, an essential factor that expresses a solution's chemical conditions (acidity/alkalinity) for a broad array of applications. In this context, at standard conditions (25oC), the pH of hydrochloric acid [pH=-0.434ln (M) +0.0005], R2=1] was mathematically designed against its molar concentrations (0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45 & 0.50M) with theoretical hydrogen ion concentration algorithms in solution over a web-based software interface. This model can therefore be applied alternatively to the pH determination of standard solution of hydrochloric acid (molarity) at the specified condition.
