Solid State Double Displacement Reaction at Room Temperature
‘Double displacement reactions’ are commonly observed insolutions and aqueous phase. They are less common in solidphase and generally requires high temperature to take place.However, in this article, we report double displacement reactionstaking place in solid phase at room temperature. Wealso highlight the criteria required for the occurrence of displacementreactions in solid state at room temperature. Thedriving force for all the double displacement reactions is explainedusing Pearson’s hard and soft acid and base (HSAB)concept, and in few cases involvement or aid of water of hydrationis observed.

A Green Approach for Complexometric Titration
Gnanamani Simiyon G Ansha Elizabeth Mammen
Green and sustainable methods have sparked great interest lately. Action green starts from our laboratories, where young minds observe and understand the need for safer and sustainable methods. Complexometric estimation requires ammonium buffer to maintain high pH. This article explains a green method by replacing ammonium buffer and later highlights its advantage.

Christmas Tree Model of Periodic Table of Chemical Elements
Gnanamani Simiyon G Mary Vergheese Nancy Sagunthala J Nivetha B
Periodic table consists of elements arranged based on theiratomic number to understand their properties. Many periodic table representations have been reported, but the position of hydrogen and f-block elements remains unclear. We report here a simple ‘Christmas tree model’ as an alternativeto the modern periodic table.
