Can pH be adjusted via neutralization so that it can be poured down the drain?
Lab buildings at Harvard contain wastewater treatment systems for the neutralization of lab wastewater that may be mildly corrosive. Therefore, the discharge of weak corrosive solutions (5.5 < pH <10.5) to the laboratory sinks in small quantities (less than one liter per hour) is permissible. Corrosive solutions with pH ranges (2.0< pH<5.5) and (10.5
