|---|---|
| Penampilan (Penampilan) | Putih atau of-putih bubuk atau kekuatan kristal, bau |
| Kelarutan (solubility) | Pada suhu kamar, asam sitrat adalah bubuk kristal putih (crystalline powder). Hal ini dapat ada baik dalam bentuk anhidrat (bebas air) atau sebagai monohidrat. Bentuk anhidrat mengkristal dari air panas, sedangkan bentuk monohidrat ketika asam sitrat mengkristal dari air dingin. Monohidrat dapat dikonversi ke bentuk anhidrat dengan memanaskannya di atas 74 c. Asam sitrat juga larut dalam etanol absolut (anhidrat) (76 bagian asam sitrat per 100 bagian etanol) pada 15 derajat celcius. Dalam struktur kimia, asam sitrat memiliki sifat-sifat yang sama dengan asam karboksilat lainnya. Ketika dipanaskan di atas 175 ° C, ia terurai melalui hilangnya karbon dioksida dan air. |

Penggunaan dan pembuatan:
1. Asam sitrat adalah asam organik lemah yang dikenal sebagai bahan kimia komoditas, karena lebih dari satu juta ton diproduksi setiap tahun oleh fermentasi mikologis dalam skala industri menggunakan larutan gula mentah, seperti molase dan strain Aspergillus niger. Asam sitrat didistribusikan secara luas dalam tanaman dan dalam jaringan hewan dan cairan dan ada dalam jumlah yang lebih besar dari rahmat dalam berbagai buah-buahan dan sayuran, terutama dalam buah jeruk seperti lemon dan jeruk nipis. Asam sitrat terutama digunakan sebagai pengasam, agen rasa dan agen chelating.
2. Digunakan dalam agen pengekstrakan untuk logam jejak; penentuan fosfat pentoxide yang larut dalam sitrat.
