In the previous post, we learned that getting an appropriate representative sample for analysis is a very important step in getting accurate results. In this

We talked about different methods of analysis in the previous post and inferred that only with experience and intuition, we can choose the correct way
149.Methods of Analysis.
Analytical chemistry is all about analysis. In this post, we shall look at the various methods of analysis that we encounter in this branch of
148.Concentration units (7).
1. Calculate gram equivalents of the following – (Given – Eq.wt of O=8,Al =9)i)7 × 10-3 kg of oxygen.ii) 4.5 × 10-3 kg of aluminium
147.Concentration units – Normality (5).
In the previous posts, we have studied in detail, how to find n-factor and equivalent weight for a number compounds. In this post we shall
146. Concentration units – Normality (4).
SALTS Salts are ionic compounds, consisting of cations (positively charged ions) and anions (negatively charged ions). e.g.- CuSO4 ⇒ Copper sulfate is a salt that
144.Concentration units – Normality (2).
In this post, we will specifically look at some acids whose n-factor calculation can seem a little tricky. We will study the structure of these
143.Concentration units – Normality (1).
4.Normality Normality is a concentration unit that uses chemical equivalent or gram equivalent term. This concentration term is not very commonly used in today’s laboratories.
In analytical chemistry one often has to deal with solutions and thus it is very important to know parameters used to define concentration. A solvent
141.The mole concept(4).
Before starting to solve problems on the mole concept, let us jot down a few important formulae – Let us solve some problems based on
140.The Mole concept(3).
In the previous post, we discussed how to relate a measurable quantity , volume , to a mole. In this post we will discuss how
139.The Mole Concept (2)
In the last post we left some questions unanswered. Questions like –How does one relate the number of particles to volume and mass of the
