KIN 2500 Chapter : Ch08
Document Summary
Memorize strong acids and bases from page 76. Hc7h5o2 (any other acid not on list to the left. Nh3 combines with water to release oh- which is basic. Nh3(g) + h2o(l) nh4 (any other base not on list to the left. +(aq) + oh- (aq) is a weak base) These are ionic compounds with ions that are soluble in water. Examples: strong acids, strong bases, soluble ionic compounds such as pbs, caso4, lioh, . Examples: a weak acid, such as hclo2 or a weak base, such as nh3. Do not conduct electricity in an aqueous solution. Other examples: sugar c6h12o6, o2, ch4, . These are molecular compounds that do not break up into ions in an aqueous solution. Examples: methanol ch3oh, ethanol ch3ch2oh, propanol ch3ch2ch2oh, hcooh. Note: you do not need to memorize the following chart which is found at the top of page 81. Li+, na+, k+, rb+, cs+, fr+ (always soluble)
