Inorganic Chemistry(d block) is a free educational application designed for Android users who are interested in improving their knowledge of D block inorganic chemistry. The app provides a basic understanding of the properties of D block elements, such as melting and boiling points, metallic nature, ionization energy, varying oxidation states, and catalytic activity. It also covers electronic configurations, rearrangements in electronic configurations, transition elements, features of transition elements, oxides formed by D block elements, and different complexes of D block elements.

The app features a simple and attractive user interface, with each section well described with text, images, and graphs. Currently, the app only contains information about 3d Block elements. The developers, Zanoj Mobi Apps, invite users to follow them on their social media accounts and to rate and review the app if they find it helpful.
