When a strong acid-strong base neutralization reaction is also a limiting reactant situation, the leftover reactant will determine your final solution pH. Remember that a limiting reactant indicates that you will run out of one reactant first.

Considering the reaction of potassium hydroxide and hydrobromic acid, notice that if you have excess acid leftover it would react with water to produce H3O+ ions in solution: HBr + H2O → Br- + H3O+

If you have excess base left over, it will dissociate in water to produce OH- ions: KOH → K+ + OH-

You mix 2 moles of HBr with 3 moles of KOH in enough water to make 1 L of solution. What is the pH of your final solution?

Explanation:

As you can see, you'd need

0.02625

moles of potassium hydroxide in order for all the moles of iron(III) hydroxide to react. Since you have fewer moles of potassium hydroxide than you'd need, potassium hydroxide will act as a limiting reagent.

will take part in the reaction. Since iron(III) nitrate and iron(III) hydroxide are in a

1

:

1

mole ratio in the balanced chemical reaction, you can say that the reaction will produce

0.00330

moles of iron(III) hydroxide.

Use the compound's molar mass to convert this to grams
