Name the Strong Acids and Worlds Strongest Acid

Name the Strong Acids and World's Strongest Acid Most of the standardized tests students take, like the SAT and GRE, are based on your ability to reason or to understand a concept. The emphasis isnt on memorization. However, in chemistry there are some things you just have to commit to memory. Youll remember the symbols for the first few elements and their atomic masses and certain constants just from using them. On the other hand, its harder to remember the names and structures of the amino acids and the strong acids. The good news, regarding the strong acids, is any other acid is a weak acid. The strong acids dissociate completely in water. Strong Acids You Should Know HCl - hydrochloric acidHNO3 - nitric acidH2SO4 - sulfuric acidHBr - hydrobromic acid HI - hydroiodic acidHClO4 - perchloric acid The Worlds Strongest Acid Although this is the strong acid list, probably found in every chemistry text, none of these acids hold the title of Worlds Strongest Acid. The record-holder used to be fluorosulfuric acid (HFSO3), but the carborane superacids are hundreds of times stronger than fluorosulfuric acid and over a million times stronger than concentrated sulfuric acid. The superacids readily release protons, which is a slightly different criterion for acid strength than the ability to dissociate to release a H ion (a proton). Strong Is Different from Corrosive The carborane acids are incredible proton donors, yet they are not highly corrosive. Corrosiveness is related to the negatively-charged part of the acid. Hydrofluoric acid (HF), for example, is so corrosve it dissolves glass. The fluoride ion attacks the silicon atom in silica glass while the proton is interacting with oxygen. Even though it is highly corrosive, hydrofluoric acid is not considered to be a strong acid because it does not completely dissociate in water.Strength of Acids Bases | Titration Basics
