Conclusion


 * Since the rain did not turn to red or dark red, my hypothesis was incorrect. I thought that there will be some slight acid in the rain water but there was not. The rain water had turned purple but purple than the distilled water. Pure distilled water which I used has a ph of about 7.0 and normal rain water is around 5.6. Rain water is slightly acidic because of carbon dioxide and fumes which float up and react to the tiny droplets in clouds which form sulphuric and nitric acid. Then the rain from those clouds falls as a very weak acid which is known as acid rain. If the Ph of rain drops is lower than 5.6, it is considered acid rain. **
