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 CompoundsNaming 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 TypeA 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 ElectrolytesStrong 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.

Weak ElectrolytesWeak 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 15% 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!
