TSP stands for which chemical compound?

• A. Trisodium Phosphate
• B. Trisodium Phosphate Dodecahydrate
• C. Tri-Sodium Phosphate
• D. Trisodium Phosphate Dihydrate

Answer: (A)

Trisodium phosphate is the common meaning behind the acronym TSP. It refers to the chemical salt Na3PO4. In everyday naming, TSP is understood to denote the anhydrous form, the base salt, even though hydrates exist (for example, the dihydrate and dodecahydrate are the same salt with water molecules attached). The other options either use a stylistic variation in spelling or specify a hydrated form, which are technically different in formula from the simple base salt. So the best match for TSP is trisodium phosphate.
