Choose the correct option ph of water of acid rain is

You may have heard the word “pH” used to describe drinking water quality, but do you know what it means? pH is a measurement of electrically charged particles in a substance. It indicates how acidic or alkaline (basic) that substance is. The pH scale ranges from 0 to 14: • Acidic water has a pH lower than 7. Strongly acidic substances can have a pH of 0. Battery acid falls into this category. • Alkaline water has a pH of 8 or above. Strongly alkaline substances, such as lye, can have a pH of 14. • Pure water has a pH of 7 and is considered “neutral” because it has neither acidic nor basic qualities. Freshwater pH varies across the world depending on weather patterns, human activity, and natural processes. Water with a very low or high pH can be a sign of chemical or heavy metal pollution. Water that doesn’t fall in the “safe” pH range of 6.5 to 8.5, particularly if it’s alkaline, isn’t necessarily unsafe. However, very alkaline water can have an unpleasant smell or taste, and it can also damage pipes and water-carrying appliances. Acidic water with a pH of less than 6.5 is more likely to be contaminated with pollutants, making it unsafe to drink. It can also corrode (dissolve) metal pipes. Many municipal water suppliers voluntarily test the pH of their water to monitor for pollutants, which may be indicated by a changing pH. When pollutants are present, water companies treat their water to make it safe to drink again. Despite the many health claims made by alkaline water d...

The correct answer is 5. Key Points • Acid Rain • Rainwater with a pH less than 5.6 is calledAcid rain. Hence, Option 1 is correct. • Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. • When sulfur dioxide and nitrogen oxides are released into the air, they react with water and oxygen and produce sulphuric and nitricacids. Thus it forms acid rain. • Acid Rain as the name suggests can be said to be the precipitation of acid in the form of rain in the simplest manner. When atmospheric pollutants like oxides of nitrogen and sulfur react with rainwater and come down with the rain, then this results in Acid Rain. Additional Information • • Effects of Acid rain • Wherever acid rain falls it can have a serious effect on soil, trees, buildings, and water. • It is very dangerous as it causes serious damages to living organisms as well as non-living things. • Acid rain runs off the land and ends up in streams, lakes, and marshes. • The worst affected are things made from limestone or sandstone as these types of rock are particularly susceptible and can be affected by air pollution in gaseous form as well as by acid rain.

The precipitation is not necessarily wet or liquid; the definition includes dust, gases, rain, snow, fog and hail. The type of acid rain that contains water is called wet deposition. Acid rain formed with dust or gases is called dry deposition. The precipitation is not necessarily wet or liquid; the definition includes dust, gasses, rain, snow, fog and hail. The type of acid rain that contains water is called wet deposition. Acid rain formed with dust or gasses is called dry deposition. Causes of acid rain The term acid rain was coined in 1852 by Scottish chemist Robert Angus Smith, according to the Royal Society of Chemistry, which calls him the "father of acid rain." Smith decided on the term while examining rainwater Though manmade pollutants are currently affecting most acidic precipitation, natural disasters can be a factor as well. For example, volcanoes can cause acid rain by blasting pollutants into the air. These pollutants can be carried around the world in jet streams and turned into acid rain far fr...
