Question

Potassium chlorate, KClO3, acts as an oxidizing agent in matches, explosive, flares, and fireworks. In the equation below it is former from the element chlorine and potassium hydroxide
3 Cl2 + 6 KOH --> KClO3 + 5 KCl + 3H2O

-write a conversion factor that could be used to convert between moles of potassium hydroxide and moles of potassium chlorate

- How many moles of potassium chlorate form when 2 moles of potassium hydroxide react completely?

- What is the maximum number of moles of KClO3 that could form in the combination of Cl2 with 9.0 moles of KOH?

Explanation / Answer

1) moles of potassium hydroxide/moles of potassium chlorate = 6:1

2) using the above relation :-

2/moles of potassium chlorate = 6:1

or, moles of potassium chlorate = 1/3 = 0.334

3) assuming Cl2 to be in excess

using the above relation :-

9/moles of potassium chlorate = 6:1

or, moles of potassium chlorate = 9/6 = 1.5
