This doesn't require any work, Ijust don't know what 0.2 N HClO4 means!!! I know that 0.2 M means molarityand concentration (moles/liter) but I have no idea what Nmeans. Is it nanomoles orsomething??? Thanks!! Most descriptive answergets lifesaver by tonight This doesn't require any work, Ijust don't know what 0.2 N HClO4 means!!!

Explanation / Answer

Normality highlights the chemical nature of salts: in solution,salts dissociate into distinct reactive species (ions such asH+, Fe3+, or Cl-). Normalityaccounts for any discrepancy between the concentrations of thevarious ionic species in a solution. For example, in a salt such asMgCl2, there are two moles of Cl- for everymole of Mg2+, so the concentration of Cl- issaid to be 2 N (read: "two normal"). Further examples are givenbelow.
