1.55 m

0.0968 m

10.3 m

0.645 m

2.)which of the following describes the properties of an acid?

are generally proton donors

produce h+ ions in solution

are electron pair acceptors

may include all of these characteristics

3.)the greater the percent ionization of an acid, the

stronger the acid

weaker the acid

more hydrogen atoms the acid molecule has in its formula

more [oh-] ions are in solution

4.)what do larger values on the ph scale represent?

higher concentration of h3o+ ions

lower concentration of h3o+ ions

lower concentration of oh- ions

more acidic the solution
