Acid rain

Question 1

2 gases involved

Answer 1

-sulfur dioxide dissolves in water to produce sulfurous acid
-oxides of nitrogen dissolve to produce nitrous and nitric acids

Question 2

2 effects of acid rain

Answer 2

-Denature proteins/enzymes by taking out of range of tolerance such as ocean acidification with coral
-mobilises toxic metal ions

Question 3

2 ways of controlling acid rain

Answer 3

-Flue gas desulfurization , can be wet or dry , gas passed through bed of crushed calcium carbonate which reacts to produce solid calcium sulfur , which could in some cases be used to make gypsum building plaster
-Coal desulfurization , crush up and put in stream of flowing water which separates coal and sulfur

Question 4

1 way of controlling NOX which would therefore control acid rain

Answer 4

-catalytic converter turns NOX into nitrogen and oxygen
