Class 12 Chemistry | Volumetric Analysis – Lecture 01 | Acidity & Basicity of Acids, Bases & Salts

Description:
Welcome to Lecture 01 of Volumetric Analysis for Class 12 Chemistry (NEB Curriculum).
In this session, we begin our study of volumetric analysis by first understanding an essential concept — acidity and basicity of acids, bases, and salts, which forms the backbone of acid-base titration.

In this lecture, you will learn:

Introduction to Volumetric Analysis – Definition, importance, and role in chemical analysis.

Acidity of Acids – Concept of basicity of an acid (number of ionizable hydrogen ions), with examples like HCl, H₂SO₄, and H₃PO₄.

Basicity of Bases – Understanding the number of hydroxide ions a base can release, with examples like NaOH, Ca(OH)₂, and Al(OH)₃.

Acidity & Basicity of Salts – How salts can be neutral, acidic, or basic depending on the acid and base from which they are formed.

Practical Relevance – Why knowing acidity/basicity is important for selecting the correct titration method, indicator, and calculations.

Basic Laboratory Preparation – Overview of apparatus like burette, pipette, and conical flask, along with safety and accuracy tips.
