Chapter 4 - Acids and Redox

Question 1

oxygen bonded with chlorine is called?

Answer 1

chlorate

Question 2

oxidation state must always add up to?

Answer 2

molecule/atom/ions overall charge (to balance it out)

Question 3

oxidation state of Group 1 atoms?

Answer 3

+1

Question 4

oxidation state of Group 2 atoms?

Answer 4

+2

Question 5

oxidation state of oxygen?

Answer 5

-2
except in peroxides, it is -1
depends when with Fluorine

Question 6

oxidation state of chlorine?

Answer 6

-1

Question 7

oxidation state of fluorine?

Answer 7

-1

Question 8

oxidation state of hydrogen?

Answer 8

+1

except in metal hydrides -1

Question 9

oxidation state of manganese?

Answer 9

transition metal so can change

Question 10

oxidation state of iron?

Answer 10

changes, typically II or III

Question 11

why does oxygen’s oxidation state change when it is bonded to fluorine?

Answer 11

fluorine is much more electronegative than oxygen, and so has a greater share of the electrons

Question 12

what is the reducing agent?

Answer 12

the atom/compound that is oxidized (increase in oxidation state)

Question 13

what is the oxidising agent?

Answer 13

the atom/compound that is reduced (decrease in oxidation state)

Question 14

can an atom be oxidised AND reduced in a reaction?

Answer 14

yes, oxygen can as it is commonly produced in more than one compound on the product side
