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
145.Concentration units – Normality (3).
BASES In general, a base is a compound that yields OH– ion/s on dissociation. Example 5 – Let us now consider a base, sodium hydroxide
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.
142.Concentration units.
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
138.The Mole Concept(1).
In this post, we are going to study one of the most seminal concepts, not only in analytical but in entire chemistry. Understanding this concept
137.Introduction(2).
9.Confidence Limit (CL)- The confidence limit is the level of confidence we have about a value being statistically significant. Confidence Limit (CL)= 100 × (1 − α)
136. Introduction(1).
From this post onwards we will start getting acquainted with some fundamentals of analytical chemistry. What is analytical chemistry? What all topics does it encompass?
135. Practice problems(2).
