What"s in a Name?

The inquiries asked ~ above this quiz are of five simple forms:What is the formula of...?What is the surname of...?What type of compound is...?Which the the following is a...?What room the principal types in a systems of...?It is really important for chemists to have the ability to answer thesequestions through confidence. Clearly the very first two are vital for communicating in the language the chemistry.But that"s not all. The names of compound are acquired from the surname of elements and also ions. We have to be ableto identify compounds by their type so as to havesome idea the what their properties are. Names offer us a large clueto properties, because the system that has been arisen fornaming link is based upon the form of compound being named.

Learning how to surname Chemical Compounds

Naming compounds and also identifying types is a lot favor checkers: The rules aresimple, but being successful takes numerous practice.Don"t intend to obtain this down pat overnight, and whatever friend dodon"t suppose to be able to cram this because that an exam. This quiz can aid yousharpen your an abilities and acquire the trust you have to perform well onyour exam. Choose a group such together binary molecular compounds or solid acids,study from your publication for 30 minutes, then fire up this quiz and see exactly how well girlfriend do.If you execute this every day for a main or two, you"ll be amazed just how much friend know.

Categorization through Electrolyte Type

A convenient categorization of compound is based upon the degree to which theybecome be separated (+) and also (–) ions when they dissolve in water. To a certainextent, the means we surname a compound relies on the type of electrolyte the is.

Strong Electrolytes

Strong electrolytes separate 100% into ions as soon as they dissolve in water.They include solid acids, strong bases, and also salts. Strong acids and strong bases areeasy to identify. (There are just 7 solid acids and also about5 common strong bases.) Salts room a little trickier come name, butstill basic to identify, as all contain steels as their (generally) first-listed element.The Seven solid AcidsFive strong BasesExamples that 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 instances how comparable the names are within each category.

Weak Electrolytes

Weak acids and also weak bases make up the course weak electrolytes,which carry out not fully dissociate in water. In fact, this compounds are frequently only 1–5% dissociated. Principally they space in the type written when in water.Weak acidformulas usually start with H, and weak basic formulasalways save on computer N. (Although no all compound containing nitrogen space weak bases, every weak bases contain nitrogen.)It"s tricky. To it is in honest, most practicing chemists simply look these points up ~ above tables!Six common Weak AcidsThree typical Weak Basesammonia, NH3pyridine, C5H5Nmethylamine, CH3NH2
hydrofluoric acid, HFhydrocyanic acid, HCNacetic acid, HC2H3O2nitrous acid, HNO2sulfurous acid, H2SO3chlorous acid, HClO2
Notice the weak mountain and strong acids are named similarly, so simply knowing thename the an mountain won"t tell us if the is weak or strong. However, weak bases havea entirety different--and at this phase in her understanding, probably irrational--naming system.Fortunately, you probably won"t have to know an ext than two or 3 names that weak bases.(Notice, though the there is "on" or "in" in the weak basic names, and also there is a nitrogen atomin your formula. This is no coincidence.)


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


What"s in a name? Well, the surname of a link can provide you part clue asto just how it reacts, at the very least what happens once it disappear in water. If youremember the by learning exactly how to surname chemical compounds girlfriend are likewise learning hints about how lock react, climate the job of learning names might be easier for you.YOU have the right to DO IT!
