Oh, honey, when sulphur dioxide and nitrogen oxide get together with water in rain clouds, it's like a chemistry party you didn't ask to attend. They form sulfuric acid and nitric acid, which can make rain more acidic than your ex's attitude. It's called acid rain, and it's not great for the environment, but hey, at least science is doing its thing.
sulphur dioxide condenses in the clouds, then it falls with the rain. PH 4
It is due to the Fact the Venus´s atmosphere is 93 times more dense that that of the Earth and is made up of mostly Carbon Dioxide, with traces of nitrogen and sulphur dioxide. This high concentration of CO2 with thick clouds of sulphur dioxide make it the perfect greenhouse effect combination. Couple that with Venus´s closeness to the Sun and you have the hottest planet in the solar system.
Basically, fuels from factories, cars, lorries, etc. are released into the atmosphere and when clouds form, the sulphur dioxide gets dissolved into the clouds. The rain then becomes polluted with sulphuric acid and thus becomes acid rain.
Sulpur Dioxide is the main chemical in acid rain. The Sulphur contained in coal, (which is burnt for industrial purposes) is released into the atmoshpere as Sulphur Dioxide. The Sulphur dioxide can be blown by the wind and reacts with water (clouds) to form Acid Rain.
When sulfur dioxide reacts with water in rain clouds, it forms sulfuric acid through the following chemical reaction: SO2 + H2O → H2SO3 → H2SO4 (sulfuric acid). Similarly, nitrogen oxides react with water to form nitric acid through the following chemical reaction: NOx + H2O → HNO2 → HNO3 (nitric acid). These reactions result in the formation of acid rain, which can have detrimental effects on the environment and ecosystems.
it mixes with clouds and creates acid rain
Sulphur Dioxide and Nitrogen Oxides are produced in countries like Germany, the UK and Poland, and the prevailing winds blow clouds of acid rain vapour over Sweden, where the sulphur acidifies the soil and stunts growth.
Clouds are primarily made up of water vapor, but they also contain other gases such as nitrogen, oxygen, and carbon dioxide.
Power stations, factories and cars all burn fuels and they all produce gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids.The rain from these clouds then falls as very weak acid - known as "acid rain".
Venus has an atmosphere of 96% carbon dioxide. It is also completely covered with clouds consisting of droplets of concentrated sulphuric acid. These cloud tops also show traces of sulphur dioxide, solid sulphur and chlorine. The surface temperature is 460oC (860oF).
Sulphur dioxide is released along-with similar other dangerous gases from the chimney of industries. These gases leach into the atmosphere and mix with air,dust,moisture to form huge black clouds. Thus, when the rain clouds get attracted to the sulphur containing clouds, acid rain occurs.
the sulphur is a base in fossil fuels (in this case coal). when the coal burns the sulphur reacts with the oxygen in the air to produce sulphur dioxide which reacts with water vapour to form acid rain
