Reactions Of Acids- Strong & Weak Acids

Question 1

what happens acid molecules in aqueous solutions

Answer 1

they ionize and release H+

Question 2

what are strong acids

Answer 2

strong acids fully ionize in aqueous solutions

Question 3

give 3 examples of strong acids

Answer 3

hydrochloric acid, sulphuric acid and nitric acid

Question 4

what are weak acids

Answer 4

weak acids partially ionize in aqueous solutions

Question 5

how can you tell something is a weak acid

Answer 5

if it has a reversible reaction symbol for the arrow

Question 6

give 3 examples of weak acids

Answer 6

carbonic acid, ethanoic acid and citric acid

Question 7

the __ scale gives us an idea of the _____________ of hydrogen ions

Answer 7

the ph scale gives us an idea of the concentration of hydrogen ions

Question 8

why do strong acids have a lower ph compared to weak acids for a given concentration

Answer 8

because strong acids fully ionize producing a greater concentration of hydrogen ions

Question 9

as the ph scale __________ by one unit, the concentration of hydrogen ions increase by __ times

Answer 9

as the ph scale decreases by one unit the concentration of hydrogen ions increase by 10 times

Question 10

what is the 10 times difference called

Answer 10

1 order of magnitude

Question 11

what does the concentration of an acid tell us

Answer 11

the amount of acid molecules in a given volume of solution
