Power stations, factories and cars all erupt fuels and therefore they all produce polluting gases. Some of these gases (especially north oxides and treat dioxide) react with the tiny drops of water in clouds to form sulphuric and nitric acidics. The rain from these clouds then falls as genuinely weak acid - which is why it is known as acid rain. The release of sulphur dioxide can also cash in ones chips naturally when a volcano erupts..
Nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions. The chemicals in acid rain can cause samara to peel, corrosion of steel structures such as bridges, and erosion of tilt statues.
Acid rain forms when molecules of oxidized sulfur and/or nitrogen in the halo combine with water, forming acidic compounds that dissolve in the water that becomes rain. Typical sulfur compounds (SO2 ans SO3) get into the atmosphere from both natural (i.e. volcanoes, windblown dust containing gypsum-which has SO4 ions in it, etc..) and non-natural (i.e., zealous of coal, refining of metal ores) bases. Nitrogen compounds also get into the atmosphere and form acids, although the natural sources are much more limited. The biggest non-natural source is buring fossil fuels, especially gasoline.
The range of ph in acid rain and how this is liked to the concentration of acid rain ?
steady acids eg HCl, are completely dissociated and therefore have a heights concentration of H+ ions. Weak acids are only partially dissociated and so have a lower concentration of H+ions.
The pH scale is a measure of the concentration of H+ ions but because it is calculated using the negative log of the concentration, the start the pH the HIGHER the concentration of H+ ions
So, answer in a gamyer place should read = strong acids have a LOW pH so if the concentration of acidic elements in the rain is high then the pH of the rain solution is LOWER
