In a reaction sequence, one or more products are generally formed. Let us see how the reaction of H2SO4 and Cu occurs. Sulphuric acid mainly exists as an aqueous solution as it is hygroscopic in nature. Copper(Cu) is a transition metal with a reddish lustre,playing a huge role in industries. Copper does not undergo corrosion … Read more
There are certain reactions which show certain colour change in the product. Let us look at such beautiful reactions and their properties. Sulphuric acid, hygroscopic and colourless, is a lab reagent that is corrosive in nature. Potassium Sulphide is also hygroscopic and a toxic compound having high solubility in water but low in organic solvents. … Read more
Colour change is an important criterion to cause a reaction. Let us see if this reaction shows any such changes. Sulphuric acid,colourless, mostly exists with water due to its hygroscopic nature. Methyl amine, the simplest of primary amines, has a peculiar pungent odour. It appears as a colourless gas with very low boiling point of … Read more
Iron is an essential element. Combining the ion with sulphate gives an interesting compound. Iron(II) Sulphate(FeSO4) belongs to the class of salts having affinity towards water. It can be produced displacing the lesser reactive metal sulphates.In the olden days, FeSO4 was made into iron gall ink for painting and scribbling but can destroy the paper … Read more

Nb electronic configuration: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 4d4 5s1.Niobium(Nb) is a transition metal present in group five of the table, with a soft and ductile nature and mass number-92. It serves … Read more
There are 118 identified elements in the periodic table. Facts about a specific element are discussed in this article. Ruthenium electronic configuration: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 4d7 5s1. Ruthenium(Ru) is a partly inert transition metal present in group eight of the table, having a mass number of 101.07. Identified for its … Read more
In a periodic table, there are 118 identified elements. In this article, we are discussing about one such element. Radon(Rn) is a nobel gas element present in group eighteen of the table, having very low reactivity and mass number of 222. Rn is radioactive and decays to series of unstable isotopes. In 1899, it was … Read more
There are 118 identified elements in the periodic table. In this article, we are talking about one such element. The electronic configuration of Rubidium is: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1. Rubidium(Rb) is an alkali metal present in the fifth row of the table, having higher density than water. Identified for its … Read more
The formation of salts is an interesting way to understand the chemistry of acids and bases. Let us if this reaction provides us with such example. Hydrochloric acid can exist in both liquid and gaseous (hydrogen chloride) forms.Potassium oxide is a famous yellow reagent having an antifluorite crystal lattice. It reacts vigorously in water to … Read more
A major way to detect product formation is a colour change. Let us if this reaction provides us with such example. Hydrochloric acid can exist in both liquid and gaseous (hydrogen chloride) forms.Potassium Dichromate is a famous orange-coloured reagent in analytical chemistry, mainly in titration reactions. It serves as a good oxidising agent, producing different … Read more
