The formation of the iron(III) thiocyanate complex ion is an exothermic equilibrium system. For each change to the system, indic
ate how the concentration of each species in the chemical equation will change to reestablish equilibrium. An up arrow indicates an increase in concentration, a down arrow indicates a decrease in concentration, and leaving it blank means there is no change in the concentration.
The equation for the formation of iron(III) thiocyanate complex ion is
Fe³⁺ + SCN⁻ ⇄ Fe(SCN)²⁺
Three factors affect the equilibrium of a reaction
temperature
pressure (in gases)
concentration
Since the formation of Fe(SCN)²⁺ is an exothermic reaction (delta H is negative); an increase in temperature will favor the backward reaction and more reactants will be produced. When the temperature is however reduced, the forward reaction will be favored and more products will be produced.
When the concentration of the reactants increases, the forward reaction is favored and hence more Fe(SCN)²⁺ is produced. However, when the concentration of Fe(SCN)²⁺ decreases, the backward reaction is favored and more reactants are produced.
bleaching powder is actually a mixture of calcium chloride, calcium hydroxide and calcium hypochlorite. hence it is not a single salt. It is not completely soluble in water as it composed of heavy calcium salts, which are known to be insoluble in water.
It would not be gain because it would say +6 instead of -2. Having a -2 charge means it wants to loose 2 electrons so it can form a full shell of 8 electrons. It wants to be inert (stable).
- Hope that helps! Please let me know if you need further explanation.
flammibility is the chemical makeup of the element that makes it flamable and reactivitie is the chemical makeup of an element that is able to reacte to another element
