Phosphoric Acid Complete Neutralization

H3PO4 + 3NaOH → Na3PO4 + 3H2O

Genel Bakış

Complete neutralization of triprotic phosphoric acid requires three equivalents of sodium hydroxide, producing trisodium phosphate (TSP). The resulting solution is strongly basic because the phosphate ion is a moderately strong base. TSP was once the workhorse of industrial and household cleaning.

Günlük Örnek

TSP was a common heavy-duty household cleaner for walls and surfaces before phosphate regulations limited its use due to water pollution concerns.

Endüstriyel Önemi

Trisodium phosphate is used in boiler water treatment, as a food additive, and in heavy-duty cleaning. Environmental phosphate bans have reduced its use in consumer products.
