Test 2: Chemistry-monovalent Ions/Anions & Acid Radicals(-)

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.

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.

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-.

The correct symbol for the Permanganate Ion is MnO4-.

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.

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-.

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.

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-.

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.

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.

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).

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.

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.

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-.
