Calcium dihydrogen phosphate

Description:
Calcium dihydrogen phosphate, with the chemical formula Ca(H₂PO₄)₂, is an inorganic compound commonly used as a fertilizer and food additive. It appears as a white crystalline solid and is highly soluble in water, which makes it effective for agricultural applications. The compound is a source of both calcium and phosphorus, essential nutrients for plant growth. In terms of its chemical properties, it can act as a weak acid due to the presence of hydrogen ions in its structure. Calcium dihydrogen phosphate is also utilized in the food industry as a leavening agent and as a calcium supplement. It is generally regarded as safe for consumption, although excessive intake can lead to health issues related to phosphorus imbalance. The compound is stable under normal conditions but should be stored in a dry environment to prevent moisture absorption, which can lead to caking. Overall, calcium dihydrogen phosphate plays a significant role in both agricultural and nutritional contexts.
