Short summary
In Earth sciences, pH-driven reactions in porous environments impact natural processes like mineral dissolution and groundwater remediation. Traditional models struggle due to pore-scale complexities. This study explores how porous structure and flow rate affect mixing and chemical reactions. Surprisingly, pH-driven reactions occur faster than predicted, emphasizing water’s unique pH behavior in porous media.
