ferric chloride

Anhydrous ferric chloride, kerarre da sinadaran masana'antu - FeCl ₃ - lu'ulu'u duhu launin ruwan kasa da inuwõyinta suna kusa, ja, da shunayya, duhu kore. Matauni nauyi - 162,21 g / mol. Abu ya narke a zazzabi na 307,5 ° C, da 500 ° C fara decompose. A 100 g na ruwa da narkar da auna anhydrous gishiri:

• 74,4 g (0 ° C).
• 99 g (25 ° C).
• 315 g (50 ° C).
• 536 g (100 ° C).

Anhydrous ferric chloride (III) - sosai hygroscopic abu hanzari janyo hankalin danshi daga kewaye yanayi. A cikin iska reacts tare da ruwa juya cikin rawaya lu'ulu'u hexahydrate FeCl ₃ + 6H ₂ O. _The taro sulusi da murabba'i na anhydrous ferric chloride a abu, samu a kasuwanci, ya kai gare shi 95%. Akwai kananan adadin ferrous chloride FeCl ₂ da kuma insoluble impurities. Ciniki sunan - "Ferric chloride." The abu na wuta da kuma fashewa, amma da bayani yana mai lalatattu sakamako a kan karfe abubuwa.

Bugu da ƙari kuma masana'antu samar anhydrous crystalline taro sulusi da murabba'i ferric a cikinta (III) ne 60%. The abu ne mai launin rawaya-kasa-kasa crystalline taro ko sako-sako da guda daga cikin wannan dafa. An muhimmanci alama na ions da ferric baƙin ƙarfe - launi. Ga mataki na hadawan abu da iskar shaka na Fe ²⁺ ne halayyar greenish, hydrated ferric chloride hexahydrate - blue-kore m. A hadawan abu da iskar shaka Fe ³⁺ ions saya launi daga rawaya zuwa ruwan kasa. Domin ingantaccen kafiya a ferric chloride bayani ne reagents:
