Potassium phosphate is a generic term for the salts of potassium and phosphate ions, including monopotassium phosphate, Dipotassium phosphate, and tripotassium phosphate. It is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent and is therefore completely safe to use in spirulina cultivation.
- Dipotassium phosphate (K2HPO4) is a highly water-soluble salt which is often used as a fertilizer, food additive and buffering agent. It is a common source of phosphorus and potassium.
- A dipotassium phosphate solution is formed by the stoichiometric reaction of phosphoric acid with two equivalents of potassium hydroxide:
- H3PO4 + 2 KOH → K2HPO4 + 2 H2O
