Questions and Answers
  • 1. 

    Choose the correct symbol for the Acetate Ion (from acetic acid).

    • A.

      I-

    • B.

      C2H3O2-

    • C.

      My cat has two eyes.

    Correct Answer
    B. C2H3O2-
    Explanation
    The correct symbol for the Acetate Ion (from acetic acid) is C2H3O2-. This symbol represents the chemical formula of the acetate ion, which consists of two carbon atoms (C2), three hydrogen atoms (H3), and two oxygen atoms (O2), with a negative charge (-) indicating that it is an ion. Acetate ions are commonly found in various chemical compounds and have important roles in biological processes and industrial applications.

    Choose the correct symbol for the Bromide Ion.

    • A.

      OH-

    • B.

      I have no brains.

    • C.

      Br-

    Correct Answer
    C. Br-
    Explanation
    The correct symbol for the Bromide Ion is Br-. This is because the symbol "Br" represents the element bromine, and the negative sign ("-") indicates that the bromine atom has gained an extra electron, resulting in a negatively charged ion.

    Rate this question:

  • 3. 

    Choose the correct symbol for the Chlorate Ion (from chloric acid).

    • A.

      ClO3-

    • B.

      CI-

    • C.

      CN-

    Correct Answer
    A. ClO3-
    Explanation
    The correct symbol for the Chlorate Ion is ClO3-. This is because the Chlorate Ion is formed from chloric acid, which consists of a chlorine atom bonded to three oxygen atoms. The negative charge indicates that the ion has gained an extra electron, resulting in a negative charge. Therefore, the correct symbol for the Chlorate Ion is ClO3-.

    Rate this question:

  • 4. 

    Choose the correct symbol for the Chloride Ion (from hydrochloric acid).

    • A.

      ClO3-

    • B.

      CI-

    • C.

      Two slices of cheese minus one.

    Correct Answer
    B. CI-
    Explanation
    The correct symbol for the Chloride Ion is CI-. This is because the symbol Cl represents the element chlorine, and the negative sign (-) indicates that the ion has a negative charge. Therefore, CI- represents the Chloride Ion with a charge of -1. The other options, ClO3- and Two slices of cheese minus one, do not accurately represent the symbol for the Chloride Ion.

    Rate this question:

  • 5. 

    Choose the correct symbol for the Cyanide Ion (hydrocyanic acid).

    • A.

      CN-

    • B.

      The news station lost a "N".

    • C.

      Br-

    Correct Answer
    A. CN-
    Explanation
    The correct symbol for the Cyanide Ion (hydrocyanic acid) is CN-. This is indicated by the statement "The news station lost a 'N'." The symbol for cyanide ion is CN-, where C represents carbon and N represents nitrogen. The statement is a play on words, suggesting that the letter 'N' is missing from the word "cyanide" to form the correct symbol CN-.

    Rate this question:

  • 6. 

    Choose the correct symbol for the Dihydrogen Phosphate Ion (from hydrocryanic acid).

    • A.

      Hop twice, then hop on Pop 4 times, not!

    • B.

      H2PO4-

    • C.

      C2H3O2-

    Correct Answer
    B. H2PO4-
    Explanation
    The correct symbol for the Dihydrogen Phosphate Ion is H2PO4-. This is because the given clue "Hop twice, then hop on Pop 4 times, not!" suggests that there are two hydrogen atoms (H2) and one phosphate group (PO4) in the ion. The negative sign (-) indicates that the ion has a charge of -1. Therefore, H2PO4- is the correct symbol for the Dihydrogen Phosphate Ion.

    Rate this question:

  • 7. 

    Choose the correct symbol for the Fluoride Ion.

    • A.

      Br-

    • B.

      CI-

    • C.

      F-

    Correct Answer
    C. F-
    Explanation
    The correct symbol for the Fluoride Ion is F-. This is because the symbol "F" represents the element fluorine, and the negative sign ("-") indicates that the ion has a charge of -1. Fluoride ions are formed when fluorine gains an electron to achieve a stable electron configuration.

    Rate this question:

  • 8. 

    Choose the correct symbol for the Hydrogen Carbonate Ion (or bicarbonate from carbonic acid).

    • A.

      CIO3-

    • B.

      Happy-three is a crowd, not.

    • C.

      HCO3-

    Correct Answer
    C. HCO3-
    Explanation
    The correct symbol for the Hydrogen Carbonate Ion (or bicarbonate from carbonic acid) is HCO3-. This is because the symbol represents the elements present in the ion, which are hydrogen (H), carbon (C), and oxygen (O). The negative sign (-) indicates that the ion has a negative charge.

    Rate this question:

  • 9. 

    Choose the correct Ion to correspond with this symbol. HSO4-

    • A.

      Bromide

    • B.

      Fluoride

    • C.

      Hydrogen Sulfate (or bisulfate from sulfuric acid)

    Correct Answer
    C. Hydrogen Sulfate (or bisulfate from sulfuric acid)
    Explanation
    The correct ion to correspond with the symbol HSO4- is hydrogen sulfate or bisulfate. This ion is formed when sulfuric acid (H2SO4) loses one hydrogen ion (H+) and becomes negatively charged. The symbol HSO4- represents the hydrogen sulfate ion, which consists of one hydrogen atom, one sulfur atom, and four oxygen atoms. This ion is commonly found in various chemical compounds and plays a significant role in many chemical reactions.

    Rate this question:

  • 10. 

    Choose the correct Ion to correspond with this symbol. OH-

    • A.

      Hydroxide (from water)

    • B.

      Hydrogen Sulfate (or bisulfate from sulfuric acid)

    • C.

      Hi!

    Correct Answer
    A. Hydroxide (from water)
    Explanation
    The correct answer is Hydroxide (from water). The symbol OH- represents a hydroxide ion, which is formed when a water molecule loses a hydrogen ion (H+) and becomes negatively charged. Hydroxide ions are commonly found in basic solutions and play a crucial role in many chemical reactions. The other options, Hydrogen Sulfate and Hi!, do not correspond to the given symbol OH-.

    Rate this question:

  • 11. 

    Choose the correct Ion to correspond with this symbol. I-

    • A.

      Acetate

    • B.

      Bromide

    • C.

      Iodide

    Correct Answer
    C. Iodide
    Explanation
    The correct ion that corresponds with the symbol I- is iodide. The symbol I- represents an ion with a single negative charge, which is characteristic of iodide. Acetate and bromide are not represented by the symbol I-.

    Rate this question:

  • 12. 

    Choose the correct Ion to correspond with this symbol. NO3- 

    • A.

      Nitrite

    • B.

      Nitrate (from nitric acid)

    • C.

      Iodide

    Correct Answer
    B. Nitrate (from nitric acid)
    Explanation
    The correct ion to correspond with the symbol NO3- is nitrate. Nitrate is a polyatomic ion that consists of one nitrogen atom bonded to three oxygen atoms. It carries a negative charge, indicated by the - sign. Nitrate is commonly found in compounds such as nitrates of alkali metals and alkaline earth metals. It is also a component of nitric acid, which is where the name "nitrate (from nitric acid)" comes from. Nitrite, on the other hand, has a different chemical formula (NO2-) and is not the correct ion for the given symbol.

    Rate this question:

  • 13. 

    Choose the correct Ion to correspond with this symbol. NO2-

    • A.

      Nitrite (from nitrous acid)

    • B.

      Nitrate (from nitric acid)

    • C.

      Trivial

    Correct Answer
    A. Nitrite (from nitrous acid)
    Explanation
    The symbol NO2- corresponds to the ion nitrite. This ion is derived from nitrous acid. Nitrite ions have one nitrogen atom and two oxygen atoms, with a negative charge. Nitrate, on the other hand, has three oxygen atoms and a negative charge, and is derived from nitric acid. Therefore, the correct answer is nitrite (from nitrous acid).
