1. 1.

   A solution holds 0.01 mol of H₂SO₄ and 0.02 mol of HCl. How many moles of NaOH neutralize both completely, Ari?
2. 2.

   A solution holds 0.005 mol of H₂SO₄ and 0.012 mol of HCl. How many moles of NaOH neutralize both completely, Bo?
4. 3.

   Using the curve, why does pH jump so sharply between 24.9 and 25.1 mL, Jun?

   • The NaOH turns into an acid
   • The last H⁺ is used up there
   • The water starts to evaporate
5. 4.

   Using the curve, what is in the solution at 25.0 mL, Kira?

   Use the picture in question 3.

   • NaCl and water
   • Extra HCl
   • Extra NaOH
6. 5.

   Using the curve, why is the pH 11.96 at 30.0 mL, Luz?

   Use the picture in question 3.

   • Extra H⁺ from HCl remains
   • Extra OH⁻ from NaOH remains
   • The NaCl formed is a base
7. 6.

   Milo says every neutralization makes table salt, NaCl. Agree or disagree?

   • Agree: water and salt are the same thing
   • Agree: salt is just another word for NaCl
   • Disagree: the salt depends on the reactants
8. 7.

   Noah says HNO₃ + KOH makes NaCl and water. Agree or disagree?

   • Agree: neutralization gives NaCl each time
   • Agree: potassium turns into sodium
   • Disagree: it makes KNO₃ and water
9. 8.

   Pia says a strong acid and a strong base reach pH 7 at the equivalence point. Agree or disagree?

   • Disagree: water itself is acidic
   • Agree: the salt left is neutral
   • Disagree: the pH ends at 1
10. 9.

    What is HBr dissolved in water called, Ren?

    • Bromic acid
    • Hydrogen bromate
    • Hydrobromic acid
11. 10.

    Which acid and base make potassium sulfate, K₂SO₄, Zee?

    • H₂SO₄ and NaOH
    • H₂SO₄ and KOH
    • HCl and KOH
