Inorganic Chemistry

Acs gen chem formula sheet

Inorganic chemistry delves into the study of elements and their compounds, excluding organic molecules. It encompasses a wide range of topics, including acid-base equilibria, solubility rules, and oxidation-reduction reactions. These concepts play a crucial role in understanding the behavior of inorganic substances in various chemical systems.

Acid-Base Equilibria

Acid-base equilibria involve reactions between acids and bases, resulting in the formation of salts and water. The strength of an acid or base is determined by its ability to donate or accept protons (H+ ions). The pH of a solution, a measure of its acidity or basicity, is calculated using the following equation:“`pH =

log[H+]

When studying for the ACS General Chemistry exam, it’s essential to have a comprehensive formula sheet. This resource can be a lifesaver, providing quick access to the formulas you need. For those who are interested in legal matters, the Howard v.

“`where [H+] represents the molar concentration of hydrogen ions in the solution.

Solubility Rules

Solubility rules predict the solubility of ionic compounds in water. These rules help determine whether a compound will dissolve, precipitate, or form a gas when added to water. Some common solubility rules include:

  • Most alkali metal (Group 1) and ammonium (NH4+) salts are soluble in water.
  • Most chloride (Cl-), bromide (Br-), and iodide (I-) salts are soluble in water.
  • Most sulfate (SO42-) salts are soluble in water, except for those of barium (Ba2+), strontium (Sr2+), and lead (Pb2+).

Oxidation-Reduction Reactions

Oxidation-reduction reactions involve the transfer of electrons between atoms or ions. In these reactions, one species is oxidized (loses electrons) while another species is reduced (gains electrons). The oxidation state of an element is a measure of its electron gain or loss.The

half-reaction method is commonly used to balance oxidation-reduction reactions. In this method, the reaction is divided into two half-reactions, one for oxidation and one for reduction. The half-reactions are then balanced separately before combining them to form the overall balanced equation.

Organic Chemistry

Acs gen chem formula sheet

Organic chemistry is the study of compounds that contain carbon. These compounds are found in all living things and are essential for life. Organic chemistry is a vast and complex field, but some of the most important concepts include functional groups, IUPAC nomenclature, and stereochemistry.

Functional Groups

Functional groups are atoms or groups of atoms that give organic compounds their characteristic properties. Some of the most common functional groups include:

  • Alkanes: Contain only carbon and hydrogen atoms, and have the general formula CnH2n+2.
  • Alkenes: Contain at least one carbon-carbon double bond, and have the general formula CnH2n.
  • Alkynes: Contain at least one carbon-carbon triple bond, and have the general formula CnH2n-2.
  • Alcohols: Contain a hydroxyl group (-OH), and have the general formula CnH2n+1OH.
  • Ethers: Contain an ether group (-O-), and have the general formula CnH2n+1OR.
  • Aldehydes: Contain a carbonyl group (-C=O), and have the general formula CnH2n+1CHO.
  • Ketones: Contain a carbonyl group (-C=O), and have the general formula CnH2n+1COR.
  • Carboxylic acids: Contain a carboxyl group (-COOH), and have the general formula CnH2n+1COOH.
  • Amines: Contain a nitrogen atom with one or more hydrogen atoms attached, and have the general formula CnH2n+1NH2.

IUPAC Nomenclature, Acs gen chem formula sheet

IUPAC nomenclature is a system for naming organic compounds. It is based on the structure of the compound and the functional groups that it contains. IUPAC nomenclature is used by chemists all over the world to ensure that everyone is using the same names for the same compounds.

Stereochemistry

Stereochemistry is the study of the three-dimensional structure of molecules. It is important in organic chemistry because the three-dimensional structure of a molecule can affect its properties. For example, the optical activity of a molecule is determined by its stereochemistry.

Physical Chemistry

Acs gen chem formula sheet

Physical chemistry is the study of the physical and chemical properties of matter, with a focus on the relationship between energy and matter. It deals with macroscopic and microscopic phenomena, and its principles are used in various fields, including chemical engineering, materials science, and biochemistry.

Key formulas in physical chemistry include:

Thermodynamics

  • First Law of Thermodynamics:ΔU = Q – W, where ΔU is the change in internal energy, Q is the heat added to the system, and W is the work done by the system.
  • Second Law of Thermodynamics:The entropy of an isolated system can never decrease over time.
  • Gibbs Free Energy:G = H – TS, where G is the Gibbs free energy, H is the enthalpy, T is the temperature, and S is the entropy.

Kinetics

  • Rate Law:Rate = k[A]^m[B]^n, where Rate is the rate of reaction, k is the rate constant, [A] and [B] are the concentrations of reactants A and B, and m and n are the orders of reaction with respect to A and B, respectively.

  • Arrhenius Equation:k = Ae^(-Ea/RT), where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature.
  • Half-Life:t 1/2= (ln 2)/k, where t 1/2is the half-life, and k is the rate constant.

Electrochemistry

  • Nernst Equation:E = E° – (RT/nF)lnQ, where E is the cell potential, E° is the standard cell potential, R is the gas constant, T is the temperature, n is the number of electrons transferred, F is the Faraday constant, and Q is the reaction quotient.

  • Faraday’s Law of Electrolysis:m = (ItM)/nF, where m is the mass of substance deposited or evolved, I is the current, t is the time, M is the molar mass of the substance, n is the number of electrons transferred, and F is the Faraday constant.

  • Ohm’s Law:V = IR, where V is the voltage, I is the current, and R is the resistance.
