  • In an oxoacid such as H2SO4, ionizable hydrogen atoms are those bonded to
    Ionizable hydrogen atoms are those bonded to oxygen.
  • Rank the following solutions in order from most acidic to least acidic.
    Order by increasing pH: lowest pH is most acidic, highest pH is least acidic.
  • What is a basic anion?
    A basic anion is the conjugate base of a weak acid, such as CH3COO-.
  • HCO3- conjugate acid
    The conjugate acid of HCO3- is H2CO3.
  • For F-, enter an equation that shows how the anion acts as a base.
    F- + H2O ⇌ HF + OH-.
  • Is NH3 a strong base?
    No, NH3 is a weak base.
  • Predict whether aqueous solutions of the following compounds are acidic, basic, or neutral.
    Strong acid/strong base salts are neutral; strong acid/weak base salts are acidic; weak acid/strong base salts are basic.
  • What is the key difference between binary acids and oxyacids in terms of their composition?
    Binary acids do not contain oxygen, while oxyacids always contain oxygen along with hydrogen and a nonmetal.
  • How do you determine which binary acid is stronger when comparing acids in the same group on the periodic table?
    For binary acids in the same group, the acid with the larger atomic radius (lower down the group) is stronger.
  • Is KOH an acid or a base?
    KOH (potassium hydroxide) is a base.
  • How can you classify KOH as an acid or base?
    KOH is a base because it contains a metal (potassium) and hydroxide ion (OH−), which is characteristic of bases.
  • Is bleach an acid or a base?
    Bleach is a base.
  • Is dish soap typically a base?
    Yes, dish soap is typically a base.
  • What is the name of a reaction between an acid and a base?
    A reaction between an acid and a base is called a neutralization reaction.
  • Is bleach considered a base?
    Yes, bleach is considered a base.
  • Is soda an acid or a base?
    Soda is an acid.
  • Is laundry detergent an acid or a base?
    Laundry detergent is a base.
  • Is KI (potassium iodide) an acid or a base?
    KI is a salt, not an acid or a base.
  • Is drain cleaner an acid or a base?
    Drain cleaner is typically a base.
  • Is C2H5NH2 (ethylamine) an acid or a base?
    C2H5NH2 is a base (specifically, a weak base known as an amine).
  • Is hand soap an acid or a base?
    Hand soap is a base.
  • Is oven cleaner an acid or a base?
    Oven cleaner is a base.
  • Is drain cleaner an acid, base, or neutral substance?
    Drain cleaner is a base.
  • Is battery acid an acid or a base?
    Battery acid is an acid.
  • Is HNO3 (nitric acid) an acid or a base?
    HNO3 is an acid (specifically, a strong oxyacid).
  • Is C2H5NH2 an acid or a base?
    C2H5NH2 is a base (a weak base, specifically an amine).
  • Which type of substance will not be classified as an acid?
    A substance that does not contain hydrogen ions (H+) or does not fit the definition of a binary or oxyacid will not be classified as an acid.
  • What type of solution will turn litmus paper from red to blue?
    A basic solution will turn litmus paper from red to blue.
  • What must be added to a base to neutralize it?
    An acid must be added to a base to neutralize it.
  • What is an acid?
    An acid is a substance that typically contains hydrogen ions (H+) and can donate H+ in solution. Most acids are either binary acids (H+ with a nonmetal) or oxyacids (H+, oxygen, and a nonmetal).
  • Is CH3NH2 (methylamine) an acid or a base?
    CH3NH2 is a base (specifically, a weak base known as an amine).
  • What is produced when an acid reacts with a base?
    When an acid reacts with a base, water and a salt are produced.
  • What characterizes a substance as an acid?
    A substance is characterized as an acid if it can donate hydrogen ions (H+) in solution.
  • What characterizes a substance as a base?
    A substance is characterized as a base if it contains a metal with a negative ion (such as OH−), has a negative charge, or is an amine (contains nitrogen and hydrogen or carbon, hydrogen, and nitrogen).
  • What characterizes a strong acid or base?
    A strong acid or base is one that completely ionizes or dissociates in water, making it a strong electrolyte.
