WebCasting starts from brass bars and cores. The most important ingredient in faucet production is brass, from which the faucet body is made by means of casting. The core … WebIodometric methods depend on the following equilibrium: I2 + I − ⇌ I − 3. Since the solubility of I 2 in water is quite low, the formation of the tri-iodide ion, I 3 -, allows us to obtain useful concentrations of I 2 in aqueous solutions. The equilibrium constant for this reaction is approximately 700.
