Chapter 4 - Reactions in Aqueous Solutions
A solution is a mixture of two or more components that is homogenous.
The solute is the substance that is present in lesser quantities.
The solvent is the material that is present in greater quantities.
Aqueous solutions are those in which the solute is a liquid or solid at first, and the solvent is water.
There are two types of solutes that dissolve in water: electrolytes and nonelectrolytes.
An electrolyte is a material that, when dissolved in water, produces an electrically conductive solution.
When dissolved in water, a nonelectrolyte does not conduct electricity.
The precipitation reaction, which results in the creation of an insoluble product known as a precipitate, is a typical type of reaction that happens in an aqueous solution.
A precipitate is a solid that separates from a solution because it is insoluble.
Ionic chemicals are used in most precipitation reactions.
A metathesis reaction is a reaction in which portions of two substances are exchanged.
It is determined by the solute's solubility, which is defined as the greatest amount of solute that may dissolve in a given amount of solvent at a particular temperature.
The definitions of acids and bases given by Arrhenius are limited in that they only apply to aqueous solutions.
A proton donor is a Bronsted acid.
A proton acceptor is a Bronsted base.
The hydronium ion is the hydrated proton, H3O+(aq).
The reaction in which a Brnsted acid (HCl) contributes a proton to a Brnsted base is depicted in this equation (H2O).
Hydrochloric acid (HCl), nitric acid (HNO3), acetic acid (CH3COOH), sulfuric acid (H2SO4), and phosphoric acid are some of the most regularly utilized acids in laboratories (H3PO4).
The first three are monoprotic acids, which means that when ionized, each unit of the acid generates one hydrogen ion.
Because each unit of sulfuric acid (H2SO4) releases two H+ ions, it is a diprotic acid.
Tricrotic acids, which produce three hydrogen ions, are uncommon.
Phosphoric acid is the most well-known tricrotic acid.
While acid-base reactions are proton-transfer events, oxidation-reduction reactions, or redox reactions, are electron-transfer reactions.
A half-reaction that illustrates the electrons involved in a redox reaction in detail.
The half-reaction that involves the loss of electrons is referred to as an oxidation reaction.
A reduction reaction is a half-reaction in which electrons are gained.
Magnesium is oxidized during the production of magnesium oxide. It's called a reducing agent because it transfers electrons to oxygen, causing it to be reduced.
Because it receives electrons from magnesium, oxygen is reduced and functions as an oxidizing agent, causing magnesium to be oxidized.
It's helpful to give oxidation numbers to the reactants and products to keep track of electrons in redox processes.
The oxidation number, commonly known as the oxidation state, of an atom, indicates how many charges it would have in a molecule if electrons were transported.
Combination, decomposition, combustion, and displacement reactions are some of the most prevalent oxidation-reduction reactions.
A combination reaction occurs when two or more chemicals react to produce a single result.
The reaction of decomposition is the polar opposite of the reaction of combination.
A decomposition reaction occurs when a chemical is broken down into two or more components.
A combustion reaction occurs when a chemical combines with oxygen, usually releasing heat and light in the form of a flame.
An ion of a compound is replaced by an ion of another element in a displacement reaction
In a disproportionation process, an element in one oxidation state gets oxidized and reduced at the same time.
The amount of solute present in a given amount of solvent, or a given amount of solution, is referred to as the concentration of a solution.
Molarity (M), also known as molar concentration, is the number of moles of solute per liter of solution and is one of the most often used units in chemistry.
Where n is the number of moles of solute and V denotes the volume of the solution in liters, molarity is defined.
Gravimetric analysis is a technique for analyzing data based on mass measurements.
First, an unknown-composition sample ingredient is dissolved in water and allowed to react with another component to generate a precipitate.
The precipitate is filtered, dried, and weighed after that.
We can compute the mass of a specific chemical composition of the original sample using the mass and chemical formula of the precipitate created.
Finally, we may calculate the percent composition by mass of the component in the original compound using the mass of the component and the mass of the original sample.
Titration is the most convenient method for conducting quantitative research of acid-base neutralization processes.
In a titration, a solution with an exact concentration, known as a standard solution, is gradually added to another solution with an unknown concentration until the chemical reaction between the two solutions is complete.
A sudden change in the color of an indicator in the acid solution usually indicates the equivalence point.
The point at which the acid has completely interacted with or been neutralized by the base is called the equivalence point.
The indicators in acid-base titrations are compounds that have distinct hues in acidic and basic environments.
The transfer of electrons occurs in redox reactions, while the transfer of protons occurs in acid-base reactions.
We can titrate an oxidizing agent against a reducing agent in the same way that we can titrate an acid against a base.
When the reducing agent is oxidized by the oxidizing agent, the equivalence point is reached.
Because they have distinct hues in their oxidized and reduced forms, oxidizing agents can be utilized as an internal indicator in redox titration.
Acid-base neutralization require the same type of calculations as redox titrations.
