All of the following are basic salts except

• K₂SO₃

• K₂S

• K₂CO₃

• ZnSO₄

If 20.0 mL of 0.100 M HCl are titrated with 19.5 mL of an NaOH solution. What is the molarity of the NaOH solution?

• 0.0975 M NaOH

• 0.103 M NaOH

• 0.0103 M NaOH

• 0.975 M NaOH

What is the purpose of an indicator in the solution with the unknown concentration?

• It tells when there is enough acid in the solution.

• It tells when there is enough base in the solution

• It tells when the equivalence point is obtained.

• It tells the concentration of base

When titrating a weak base with HCl, the

• pH will be less than 7 at the equivalence point.

• pH will be greater than 7 at the equivalence point.

• pH will be equal to 7 at the equivalence point.

• titration will require more moles of acid than base to reach the equivalence point.

Which indicator is used to study neutralizations of weak acids with strong bases?

• Bromothymol blue

• methyl orange

• crystal violet

• phenolphthalein

Which one of these salts will form a neutral solution on dissolving in water?

• NaCl

• KNO₂

• NH₄NO₃

• FeCl₃

In The following neutralization reaction.

HCl + KOH --> H2O + KCl
