Question

Normal rain is slightly acidic because it has absorbed some carbon dioxide from the air. Acid rain is more acidic than normal rain because it has absorbed gases like sulfur oxides and nitrogen oxides as well. Where do these sulphur oxides and nitrogen oxides in the air come from? Acid Rain – Question 2 The effect of acid rain on marble can be modelled by placing chips of marble in vinegar overnight. Vinegar and acid rain have about the same acidity level. When a marble chip is placed in vinegar, bubbles of gas form. The mass of the dry marble chip can be found before and after the experiment. A marble chip has a mass of 2.0 grams before being immersed in vinegar overnight. The chip is removed and dried the next day. What will the mass of the dried marble chip be? A Less than 2.0 grams B Exactly 2.0 grams C Between 2.0 and 2.4 grams

Answer 1

Answer:

Normal rain absorbs carbon dioxide from the atmosphere, forming carbonic acid that is slightly acidic, so that the normal pH of rain is 5.6. Acid rain has a typical pH of between 4.2 and 4.4. Higher acidification of rain is caused by the presence of sulfur dioxide or nitrogen oxides in the atmosphere.
