Chlorine reacts with water according to the equation: #Cl_2 + H_2O -> HCIO + H^+ + Cl^-#. Given this, how do you write an equation to show how iodine reacts with water?
Iodine is strongly reactive, even though it is less extreme for iodine than for other halogens. Iodine cannot be found as an element, but rather as
When iodine is added to water, the following reaction results:
#I_2(l) + H_2O(l) -> OI^(-)(aq) + 2H^+(aq) + I^(-)(aq)#
Iodine may also occur as
#I_3^(-)(aq), HIO(aq), IO^(-)(aq), HIO_3(aq)#
Iodine can bind to many different substances, for example, other halogens. The compounds that are formed behave differently when they come in contact with water.
Solubility of iodine and iodine compounds
Water solubility of iodine is determined by temperature
#I_2 + I^-) -> [I_3]^-#
