What is a Base? A base (in chemistry) means having a pH (on the pH scale) of 8-14.It is a substance that can accept protons. A base that is dissolved in water is called an alkali. What are the properties of bases? Bases have a bitter taste (opposed to sour taste of acids) ...
An acid is a substance with a PH of less than 7. MY LATEST VIDEOS The pH scale measures how acidic or alkaline a substance is. A neutral substance such as pure water has a pH of 7! Acids form H+ions in water. The higher the concentration of H+ions, the more acidic the solution ...

Lewis Acids and Bases In the Brnsted-Lowry definition of acids and bases, a base is defined as a compound that can accept a proton. However, how does it accept the proton? One feature that Brnsted-Lowry bases have in common with each other is that they have an unshared pair of electr...
What is Acid Rain:什么是酸雨What is Acid Rain? “Acid rain” is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry. Wet deposition refers to acidic rain, fog, and snow. As this...
Strong Is Different from Corrosive The carborane acids are incredible proton donors, yet they are not highly corrosive.Corrosivenessis related to the negatively-charged part of the acid. Hydrofluoric acid (HF), for example, is so corrosive it dissolves glass. Thefluorideion attacks the silicon ato...
