    Acids and Bases Theories and Neutralization Practice Q Answer Key
    1) List four properties of an acid.
    Dissociates into H+ ions in solution, turns litmus paper red, pH is less than 7, conducts electricity, caustic and corrosive, tastes sour, reacts with metals to produce hydrogen gas through single replacement.
    2) Which ions exist in acid solutions?
    H+ or H3O+ ions (hydrogen ion or hydronium ion)
    3) List three properties of a base.
    Dissociates into OH- ions in solution, turns litmus paper blue, pH is greater than 7, conducts electricity, caustic, tastes bitter, slippery
    4) Which ions exist in base solutions?
    OH- or hydroxide ions
    5) What forms when an acid reacts with a base?
    A salt and water.
    6) What are some properties that acids and bases have in common?
    They are both electrolytes. They are both caustic.
    7) I am a substance who turns blue litmus red, neutralizes bases, and tastes sour. What am I? An acid.
    8) I am a substance who turns red litmus blue, neutralizes acids, and tastes bitter. What am I? A base.
    9) An aqueous solutions of an ionic compound turns red litmus blue. Conducts electricity, and reacts with an acid to form a salt and water. This could  be: d. LiOH
    10) Which substance can be classified as an Arrhenius acid? a) HCl
    11) Which metal will react with hydrochloric acid and produce H2 (g)? c) Mg
    12) According to the Arrhenius theory, a substance that is classified as an acid will yield: c) H+
    13) Which substance is classified as an Arrhenius base? b) NaOH
    14) State if the following observations indicate an acid or a base.
    a) A solution conducts electricity and feels slippery. Base
    b) A solution conducts electricity and reacts with a metal. Acid
    c) A solution is sour and turns blue litmus paper red. Acid.
    d) A solution reacts with an acid and produces salt. Base
    15) Choose one.
    a) CH3COOH is an acid.
    b) NH4Cl is a salt.
    c) KOH is a base.
    d) H3PO4 is an acid.
    e) Ca(NO3)2 is a salt.
    16) Write a reaction (if any) between: (Use Table K, L and J)
    a) Aluminum solid and nitric acid aqueous: Al + HNO3 --> H2 + Al(NO3)3
    b) Lithium solid and sulfuric acid aqueous: Li + H2SO4 --> H2 + Li2SO4
    c) sodium solid and acetic acid aqueous: Na + CH3COOH --> H2 + NaCH3COO
    17) Which metals do not react with acids? How do you know this?  Gold, silver and copper will not react with an acid because they are less reactive than Hydrogen (H2) according to Reference Table J.
     18) Identify the alternate theory acid and base in each of these reactions:
    HNO3 + H2O --> H3O + NO3-    HNO3= acid (proton donor) , H2O= base (proton acceptor)
    HBr + H2O --> H3O+ + Br-         HBr= acid, H2O= base
     19) Write balanced equations of neutralization reactions between these substances: (Be sure to check your oxidation states when writing the formula for the salt!)
    a) HCl + KOH --> H2O + KCl
    b) 2 HNO3 + Ca(OH)2 -->  2 H2O + Ca(NO3)2
    c) H2SO4 + 2 KOH --> 2 H2O + K2SO4
