Study Notes

Naming Acids

Acids must be in an aqueous solution.
There are two main types of acids: Binary Acids and Oxyacids
Binary Acids are made of a hydrogen atom bonded to a nonmetal atom
Oxyacids consist of a hydrogen atom bonded to an oxyanion, which is a polyatomic anion containing oxygen

Naming Binary Acids

The name of a binary acid begins with the prefix hydro
Continue the name by using the base name of the nonmetal and adding the suffix -ic acid
- For example, HCl is named hydrochloric acid

Naming Oxyacids

The name of an oxyacid is derived from the name of the oxyanion
If the oxyanion's name ends in -ate, the acid's name ends in -ic acid
If the oxyanion's name ends in -ite, the acid's name ends in -ous acid
- For example, H2SO4 is named sulfuric acid because sulfate ends in -ate
- Likewise, H2SO3 is named sulfurous acid because sulfite ends in -ite

Metals Whose Charge Is Invariant

Not all metals form multiple types of ions
The metals in Groups 1A and 2A always have the same charge
- Group 1A metals (alkali metals) always have a +1 charge
- Group 2A metals (alkaline earth metals) always have a +2 charge
The metals in Group 8A (noble gases) do not usually form ions
- They exist in their elemental form, and their oxidation state is 0
Some of the transition metals in the d-block also have invariant charges
- These include Sc, Ti, Y, Zr, Cd, Sn, Al, and Pb
Transition metals whose charge is invariant always have the same charge from compound to compound.
For example, titanium (Ti) always has a charge of +4.

Nomenclature: Naming Compounds

The general process for naming compounds includes prefixes, suffixes, and Roman numerals to indicate the charge of the cation.
The charge of the cation is then used to determine the formula of the compound
When writing the name of a compound, the cation is written first, followed by the anion
- For example, Sodium Chloride would be named NaCl
The use of prefixes and suffixes in naming compounds is a way to indicate the number of atoms of each element in a molecule
- The prefixes mono, di, tri, tetra, penta, hexa are used to indicate the number of atoms of a particular element in a molecule.
If you know the charge of a metal ion, you can use it to figure out the formula of an ionic compound, which is the main way that ionic compounds are named.
The charge of a transition metal is shown with a Roman numeral in parentheses
For example, CuSO4 would be named Copper (II) Sulfate

Naming Acids

Acids are composed of one or more nonmetals.
Acids are classified as either binary or oxyacids.
Binary Acids contain two elements: a hydrogen (H) and a nonmetal.
Oxyacids contain hydrogen (H), a nonmetal, and oxygen (O).

Naming Binary Acids

The prefix "hydro" is placed in front of the base name of the nonmetal.
The suffix "-ic" is added to the base name of the nonmetal.
The word "acid" is appended to the end of the name.

Naming Oxyacids

The name of the oxyacid is based on the name of the oxyanion present.
If the oxyanion ends in "-ite", the suffix "-ous" is used.
If the oxyanion ends in "-ate", the suffix "-ic" is used.
The word "acid" is appended to the end of the name.

Metals Whose Charge Is Invariant

Metals in group 1A & 2A (alkali and alkaline earth metals) have invariant charges.
These metals form only one type of ion.

Transition Metals

Some transition metals exhibit a range of ionic charges.
Transition metals with varying charges require a Roman numeral to denote the specific charge of the cation present in a particular compound.

Nomenclature: Naming Compounds

Acids contain one or more nonmetals.
Binary acids are composed of two elements, a hydrogen atom, and a nonmetal.
Oxyacids contain oxygen.
Naming acids:
Binary acids start with the prefix "hydro".
- The nonmetal is followed by the suffix "-ic" (acid).
Oxyacids are named by the base of the oxyanion followed by the suffix "-ic" (acid).
- Example: "sulfate" would be "sulfuric" acid, and "sulfite" would be "sulfurous" acid.
The charge of the metal cation, represented in Roman numerals, is written within parentheses after the metal's name.
- For example, Iron(II) means that iron has a +2 charge.
The charge of the metal cation is invariant from one compound to another for metals found in groups 1A and 2A, and group 8A (18). The charge is invariant for the following transition metals:
- Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Cd, Sn, La, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, and Pb.
