Description
Calcium Iodide Hydrate is a white crystalline compound that consists of calcium ions and iodide ions. It is known for its unique chemical properties and has a variety of applications across different industries.
Uses
Used in Photography:
Calcium Iodide Hydrate is used as a chemical component in the photography industry for its ability to enhance the development process of photographic films and papers. Its presence aids in the formation of latent images, which are then transformed into visible images through the development process.
Used in Animal Nutrition (Cat Food):
In the animal nutrition industry, specifically for cat food, Calcium Iodide Hydrate is used as a source of iodine. Iodine is an essential trace element that plays a crucial role in maintaining proper thyroid function, which is vital for the overall health and well-being of cats. By including Calcium Iodide Hydrate in cat food, manufacturers ensure that cats receive the necessary iodine for optimal health and prevent iodine deficiency-related issues.
Purification Methods
Dissolve the salt in acetone, which is then diluted and evaporated. This drying process is repeated twice, then the CaI2 is recrystallised from acetone/diethyl ether and stored over P2O5. It is very hygroscopic when anhydrous and is light sensitive [Cremlyn et al. J Chem Soc 528 1958]. The yellow hexahydrate has m 42o. It is soluble in H2O, MeOH, EtOH and Me2CO but insoluble in Et2O.
Check Digit Verification of cas no
The CAS Registry Mumber 71626-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,2 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71626-98:
(7*7)+(6*1)+(5*6)+(4*2)+(3*6)+(2*9)+(1*8)=137
137 % 10 = 7
So 71626-98-7 is a valid CAS Registry Number.
