Welcome to the Chemistry library! Chemistry is the study of matter and the changes it undergoes. Here you can browse chemistry videos, articles, and exercises by topic. We keep the library up-to-date, so you may find new or improved material here over time.

Father of Chemistry Overview. Chemistry is the study of matter, which is defined as everything having mass and occupied space, and the changes that it may undergo when subjected to diverse environments and situations. Chemistry is not only used in scientific investigations but it is also used in everyday life.

Hot Topic: Click Chemistry. The term "click chemistry" was introduced by K. Barry Sharpless et al. and denotes the development of a set of powerful, highly reliable, and selective reactions for the rapid synthesis of useful new compounds and combinatorial libraries through heteroatom links. Their Review in Angewandte Chemie in 2001 still ranks.

Three chemists who pioneered a useful technique called click chemistry to join molecules together efficiently have won this year’s Nobel Prize in Chemistry. Barry Sharpless at Scripps Research.

WASHINGTON, Sept. 27, 2022 — To assist with coverage of the 2022 Nobel Prize in Chemistry, the American Chemical Society (ACS) will issue a statement from ACS President Angela K. Wilson, Ph.D., after the official announcement is made from Stockholm on Wednesday, Oct. 5. Wilson will be available for interviews beginning at 6:15 a.m. ET on that.

Abū Mūsā Jābir ibn Ḥayyān, (born c. 721, Ṭūs, Iran—died c. 815, Al-Kūfah, Iraq), Muslim alchemist known as the father of Arabic chemistry. He systematized a “quantitative” analysis of substances and was the inspiration for Geber, a Latin alchemist who developed an important corpuscular theory of matter. The historical figure

(i)At higher altitudes, people suffer from a disease called anoxia. In this disease, they become weak and cannot think clearly. (ii)When mercuric iodide is added to an aqueous solution of KI, the freezing point is raised. Or 0.90 g of a non-electrolyte was dissolved in 90 g of benzene. This raised the boiling point of benzene by 0.25°C.

In terms of chemistry, Solutions are classified as mixtures of two or more substances in which the solvent is liquid and the solute is liquid, solid, or gas. There are several types of solutions, each with its own set of characteristics, but they can be divided into: True solutions and Colloidal solutions.

Sol: The liquid state of a colloidal solution is called the sol. Gel: The solid or semi-solid (Jelly like) stage of a colloidal solution is called the gel. Difference between Sol and Gel << Back to Human Physiology Notes Page You might also like… @. Difference between Colloids and Crystalloids @.
