Chemical equilibria

ALCHEM6: THE CONCEPT OF CHEMICAL EQUILIBRIUM MADE EASY Details FREE 1 year

In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time.

ALCHEM6: COMPARISON BETWEEN KC AND KP MADE EASY Details 1 year

Kc is the equilibrium constant given as a ratio between concentrations of products and reactants. The molar concentrations of the components are used for the expression of Kc.

ALCHEM6: FACTORS AFFECTING THE POSITION OF EQUILIBRIUM IN ACCORDANCE WITH THE LE’ CHATELIER’S PRINCIPLE MADE EASY Details 1 year

Le Chatelier’s principles, also known as the equilibrium law, are used to predict the effect of some changes on a system in chemical equilibrium (such as the change in temperature or pressure). The principle is named after the French chemist Henry Louis Le Chatelier.

Ionic equilibria

CHEM6: ACIDS, BASES AND SALTS MADE EASY Details 1 year

Earlier, acids, bases, and salts were characterized by the experimental testing of their aqueous solutions. An acid is defined as a substance whose water solution tastes sour, turns blue litmus red and neutralizes bases.

CHEM6: HYDROLYSIS OF SALTS MADE EASY Details 1 year

Salt is a compound formed by the neutralization reaction between an acid and a base. They generally ionize in water furnishing cations and anions. The cations or anions formed during ionization of salts either exist as hydrated ions in aqueous solutions or interact with water to regenerate the acids and bases. The process of interaction between cations or anions of salts and water is known as hydrolysis of salts.

CHEM6: BUFFER SOLUTION MADE EASY Details 1 year

A buffer is an aqueous solution that consists of a mixture of a weak acid and its salt (acid buffer) or a weak base with its salt (basic buffer). Its pH changes very little when a small amount of strong acid or base is added to it and is thus used to prevent a solution's pH change.

CHEM6: ACID–BASE TITRATIONS MADE EASY Details Unlimited

An acid–base titration is a method of quantitative analysis for determining the concentration of an acid or base by exactly neutralizing it with a standard solution of base or acid having known concentration.

CHEM6: SOLUBILITY EQUILIBRIA MADE EASY Details 1 year

A solution is a homogeneous mixture of one or more solutes in a solvent. Sugar cubes added to a cup of tea or coffee are a common example of a solution. The property which helps sugar molecules to dissolve is known as solubility. Hence, the term solubility can be defined as a property of a substance (solute) to dissolve in a given solvent. A solute is any substance which can be either solid or liquid or gas dissolved in a solvent.
