The more limited and older definition was that a base is a substance that dissolves in water and dissociates into a hydroxide or OH-ion and a positive ion. In the more general definition, a base is a substance that when dissolved in water increases the number of hydroxide ions. This defin...

(A) math (B) biology (C) physics (D) history (E) chemistry<9> Some people in New York express 2/8 as 8th Feb and others express 2/8 as2nd Aug. This can be confusing as when we see 2/8, we dont know whether it is8th Feb or 2nd Aug. However, it is easy to understand 9...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, s...
chemical reaction, we have a new definition of acidity and basicity, called "Lewis acidity/basicity." ALewis baseis a compound that donates an electron pair to another compound (the ammonia in our example). ALewis acidis a compound that accepts an electron pair (the H+ion in our example)...

Lowry or Brønsted theory explainsacid-basereactions as an acid releasing the proton and a base accepting the proton. While the acid definition is somewhat the same as that, which was proposed by Arrhenius (hydrogen ion is a proton), the definition of what constitutes a base is much broader...
than yours and you'll drift in that direction. There is no doubt that I was actually following that in Peking University. This is not a deliberate choice, but an opportunity given to me by such an environment. Of course, in a certain sense, it is also the result of my personal ...

They may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. In a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains of PAA will lose their protons and acquire a negative...
