The equivalence point in a titration refers to the point when the mL of the acid equals the mL of the base.
the molarity of the acid used in the reaction equals the molarity of the base used in the reaction.
the number of moles of one reactant reacts completely with the moles of the other reactant.
the acid in the flask turns clear.

If the particles in a sample of matter have an orderly arrangement and move only in place, the sample is a

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
