Concentration Terms in Physical Chemistry

An introduction about how learning this course makes sense is explained.

Hoping to see students appreciate learning this course after this lecture.

Mole concept is an important concept in Chemistry. Having clarity in this concept enables us to understand higher level concepts better.

This lecture discusses the mole concept in detail with examples and numerical problems. Explanations are given in a simplistic manner so that even a high school student can catch it easily.

After the lecture student will be better equipped to solve mole concept related numerical problems.

Mole fraction is a concentration term widely used in Chemistry to express how much of each component is present in the mixture.

Lecture takes you through the detailed explanation of the concept with solved numerical problems.

Mass %, Volume % & Mass/Volume % are 3 types of concentration terms used to express how much of a particular substance is present in the mixture. Usage of the concentration terms can be seen in most of the things we use in our day to day life like hand sanitizer, tablets, vinegar, shampoo etc.

This lecture takes you through these concentration terms in detail with the help of a numerical problem.

ppm, ppb and ppt is another set of concentration terms widely used to express that component of the mixture which is present in very low quantity. Example; fluoride, lead content of water. Metal content in the human body etc

Lecture takes you through the clear explanation of above concentration terms

'Molality' is the concentration term often used in colligative properties (elevation in boiling point, depression in freezing point, lowering of vapor pressure) related experiments where it involves a temperature change.

Lecture takes you through the clear explanation of this concentration term.

'Molarity' is the famous concentration term used in titration-lab and osmotic pressure related experiments.

There exists a slight difference between molality and molarity and the lecture concentrates on giving clarity on this line.

Along with molarity and molality, normality is also used a lot in chemistry labs. This particular concentration term is very helpful when we need to back calculate in an experiment.

Lecture explains equivalent mass, equivalents and normality in comparison to molar mass, mole and molarity.

A consolidated sheet that includes all formulas discussed in this course.

Lecture goes through solving numerical problems on the concentration terms discussed. Majorly, problems concentrate on inter-conversion of two or more concentration terms.
