Question

Elemental iodine can be produced for sale by reacting chlorine gas with potassium iodide solution. How many moles of chlorine are required to react with 4.25 moles of potassium iodide?

Answer 1

To react with 4.25 moles of potassium iodide, we would need 2.125 moles of chlorine.

Step-by-step explanation:

To determine the number of moles of chlorine required to react with 4.25 moles of potassium iodide, we need to consider the balanced chemical equation:

Cl2 + 2KI → 2KCl + I2

From the equation, we can see that the reaction requires 1 mole of chlorine (Cl2) to react with 2 moles of potassium iodide (2KI).

Therefore, to react with 4.25 moles of potassium iodide, we would need:

(4.25 moles KI) x (1 mole Cl2/2 moles KI) = 2.125 moles Cl2
