Physical Chemistry is a main section in advanced level chemistry. Equilibrium, electrolysis, kinetics, Thermodynamics are some sub sections you have to study. Physical chemistry includes more calculations than other sections in chemistry.

## How to study physical chemistry?

Physical chemitry is completely different from inorganic chemistry and organic chemistry because there are less content to remember in physical chemistry.

In physical chemistry, you have to solve so many problems to be an expert.

## Physical Chemistry Sections

• States of matter: Gases and liquids
• Thermodynamics
• Kinetics, reaction rates
• Equilibrium
• Electrolysis and Electro-Chemistry

### States of matter: Gases and liquids

Matter can exist three states. They are solid, liquid, and gaseous. In physical chemistry, we will focus on learning gas behavior. We will learn, Boyle's law, Charles' Law, ideal gas equation and more.

### Thermodynamics

Enthalpy, entropy, Gibbs free energy of reactions are studied.

### Chemical calculations

Calculate weight, concentration and pH of solution

In this tutorial, we discuss how to find pH of aqueous solution when a solid compound like NaOH is dissolved.

## Equilibrium

Acid base reaction Example

What are the acids and bases, how they react with each other and what are the products are discussed with problems.

NaOH + HCl titration curves

Titration curves are used to decide correct indicators. Different titration curves are obtained for different concentrations of NaOH and HCl solutions.

Calculate pH of Strong Bases

What is a strong base and how it behaves in water to show basic characteristics and then calculate the pH value from pOH.

Weak acid Dissociation and pH

What is a weak acid? How to calculate its pH when we know the concentration of weak acid.

Strong acid diluting and pH

A relationship between pH and strong acid concentration is obtained when strong acid is diluted by distilled water.

Relationship of weak acid concentration and pH

As strong acids, a relationship between pH and weak acid concentration is obtained when weak acid is diluted by distilled water.

Strong and weak acid solution

H+ concentration is measured when a aqueous solution contains a strong acid and dilute acid.

## Air properties

Saturated air, relative humidity definition and problems

What is saturated air and how relative humidity is calculated with water vapor mass and water vapor pressure.
