FAQ
Frequently Asked Questions
Yes, in regulated quantities. It is approved as a food additive (E340(i)) for use as an acidity regulator, stabiliser, and nutrient supplement.
Monobasic potassium phosphate (KH₂PO₄) has one potassium ion and is acidic. Dibasic potassium phosphate (K₂HPO₄) has two potassium ions and is alkaline. They are often used together to create buffer solutions.
Yes, it is a component of many water-soluble fertilisers. However, you should use a product formulated for gardening rather than pure laboratory-grade chemical, and always follow application instructions.
In chemistry, 'basic' here refers to the number of replaceable hydrogen atoms from the parent acid (phosphoric acid, H₃PO₄). 'Monobasic' means only one hydrogen has been replaced by a metal ion (potassium).
A chemical compound with the formula KH₂PO₄, consisting of potassium and dihydrogen phosphate ions, used as a buffering agent, fertilizer, and food additive.
Monobasic potassium phosphate is usually technical/scientific in register.
Monobasic potassium phosphate: in British English it is pronounced /ˌmɒnəʊˌbeɪsɪk pəˈtæsiəm ˈfɒsfeɪt/, and in American English it is pronounced /ˌmɑːnoʊˌbeɪsɪk pəˈtæsiəm ˈfɑːsfeɪt/. Tap the audio buttons above to hear it.
