Acid and Base strength

Question 1

what is the strength of an acid according to the bronsted-lowry theory

Answer 1

the ability of the acid to donate hydrogen ions to a base

Question 2

what is the strength of a base according to the bronsted0lowry theory

Answer 2

a measure of the bases ability to accept hydrogen ions from an acid

Question 3

strong acids…

Answer 3

donate protons easily, ionise completeley in water and the solution will contain ver little unreacted acid molecules remaining

Question 4

strong bases…

Answer 4

accept protons easily, completely ionise in waterto make hydroxide ions, very little unreacted base molecuules remain

Question 5

weak acids…

Answer 5

only partially ionise to form hydrogen ions in water and the soolution contains a high proportion of acid molecules remaining

Question 6

weak bases…

Answer 6

only partially ionise in water to make hydroxide ions and many of the acid molecules still remain
