What"s in a Name?

The concerns asked ~ above this quiz space of five an easy forms:What is the formula of...?What is the name of...?What type of compound is...?Which that the following is a...?What are the principal species in a equipment of...?It is really important for chemists to be able to answer thesequestions through confidence. Obviously the first two are necessary for communicating in the language the chemistry.But that"s no all. The surname of compound are acquired from the name of elements and also ions. We should be ableto identify compounds by your type so regarding havesome idea of what their properties are. Names provide us a huge clueto properties, because the device that has actually been arisen fornaming compound is based upon the type of compound being named.

Learning just how to name Chemical Compounds

Naming compounds and also identifying types is a lot prefer checkers: The rules aresimple, yet being successful takes many practice.Don"t intend to get this down pat overnight, and also whatever girlfriend dodon"t mean to be able to cram this for an exam. This quiz can help yousharpen your skills and obtain the to trust you have to perform well onyour exam. Choose a classification such as binary molecule compounds or strong acids,study native your book for 30 minutes, climate fire up this quiz and see how well you do.If you carry out this every day because that a mainly or two, you"ll be amazed just how much friend know.

Categorization through Electrolyte Type

A practically categorization of compound is based on the extent to i beg your pardon theybecome separated (+) and (–) ions once they dissolve in water. To a certainextent, the method we name a compound depends on the type of electrolyte the is.

Strong Electrolytes

Strong electrolytes separate 100% right into ions once they dissolve in water.They include solid acids, solid bases, and salts. Strong acids and strong bases areeasy to identify. (There are only 7 strong acids and also about5 common solid bases.) Salts room a bit trickier to name, butstill simple to identify, as all contain metals as your (generally) first-listed element.The Seven strong AcidsFive strong BasesExamples the Salts
hydrochloric acid, HClhydroiodic acid, HIhydrobromic acid, HBrnitric acid, HNO3sulfuric acid, H2SO4chloric acid, HClO3perchloric acid, HClO4lithium hydroxide, LiOHsodium hydroxide, NaOHpotassium hydroxide, KOHcalcium hydroxide, Ca(OH)2barium hydroxide, Ba(OH)2sodium chloride, NaClmagnesium sulfate, MgSO4ammonium nitrate, NH4NO3calcium chloride, CaCl2
Notice in these examples how comparable the names are within each category.

Weak Electrolytes

Weak acids and also weak bases make up the class weak electrolytes,which perform not fully dissociate in water. In fact, this compounds are frequently only 1–5% dissociated. Principally they are in the type written once in water.Weak acidformulas usually begin with H, and weak base formulasalways contain N. (Although no all compound containing nitrogen are weak bases, every weak bases save nitrogen.)It"s tricky. To be honest, most practicing chemists just look these points up on tables!Six common Weak AcidsThree common Weak Basesammonia, NH3pyridine, C5H5Nmethylamine, CH3NH2
hydrofluoric acid, HFhydrocyanic acid, HCNacetic acid, HC2H3O2nitrous acid, HNO2sulfurous acid, H2SO3chlorous acid, HClO2
Notice the weak mountain and solid acids are called similarly, so just knowing thename that an acid won"t tell united state if the is weak or strong. However, weak bases havea whole different--and in ~ this phase in your understanding, most likely irrational--naming system.Fortunately, you most likely won"t have to know an ext than two or three names of weak bases.(Notice, though the there is "on" or "in" in the weak basic names, and there is a nitrogen atomin their formula. This is no coincidence.)


The critical category, nonelectrolytes, is huge, containingseveral million known (i.e. Studied and named)substances. Some very important and common nonelectrolytes arebinary molecular compounds, which have a basic naming systemall their own. These incorporate such environmentally essential compounds together water, methane,carbon dioxide, carbon monoxide, sulfur dioxide, and most other contents of air.


What"s in a name? Well, the surname of a compound can give you part clue asto just how it reacts, at least what happens as soon as it dissolves in water. If youremember the by learning just how to name chemical compounds friend are likewise learning hints around how castle react, climate the job of finding out names may be easier for you.YOU can DO IT!
