Very strong acids will burn if they touch your skin and can even destroy metals. Acid rain is much, much weaker than this, never acidic enough to burn your skin. Rain is always slightly acidic because it mixes with naturally occurring oxides in the air. Unpolluted rain would have a pH value of between 5 and 6.

The pollution that causes acid rain can also create tiny particles. When these particles get into people’s lungs, they can cause health problems, or can make existing health problems worse. This ground-level ozone causes respiratory problems, like pneumonia and bronchitis, and can even cause permanent lung damage.

While acid rain cannot harm humans directly, the sulfur dioxide that creates it can cause health problems. Specifically, sulfur dioxide particles in the air can encourage chronic lung problems, like asthma and bronchitis.

Humans are affected when we breathe in air pollution, this can cause breathing problems, and even cancer. Drinking water which has been contaminated with acid rain can cause brain damage over time.

A great way to reduce acid rain is to produce energy without using fossil fuels. Instead, people can use renewable energy sources, such as solar and wind power. Renewable energy sources help reduce acid rain because they produce much less pollution.

Acid rain was first identified in North America at Hubbard Brook in the mid-1960s, and later shown to result from long-range transport of sulfur dioxide and nitrogen oxides from power plants. Hubbard Brook research influenced national and international acid rain policies, including the 1990 Clean Air Act amendments.

i) Carbonic acid ii) Sulphuric acid iii) Nitric acid iv) None of the above. Acid rain contains mineral acids like carbonic acid, sulphuric acid and nitric acid.

H2O (l) + H2CO3 (aq) ⇌ HCO3− (aq) + H3O+ (aq) Unpolluted rain can also contain other chemicals which affect its pH (acidity level). A common example is nitric acid produced by electric discharge in the atmosphere such as lightning.

Present in acid rain is CH3COOH.

Acid rain results when sulfur dioxide (SO2) and nitrogen oxides (NOX) are emitted into the atmosphere and transported by wind and air currents. The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

sulfenic acid

malic acid

Acid rain forms when molecules of oxidized sulfur and/or nitrogen in the atmosphere combine with water, forming acidic compounds that dissolve in the water that becomes rain. Acid rain in L.A. is mostly HNO3 (nitric acid) due to all of the automobile exhaust.

The Nitty-Gritty Ripe bananas are alkaline (have a pH of around 5.5), while unripe ones are acidic (have a pH of about 6.6, which is less acidic). Unripe bananas have around 4.4 Millie equivalents of organic acid per 100 grams. The primary one is oxalic acid, followed by malic, tartaric, and citric acid.

That’s because watermelon is rich in an amino acid called L-citrulline, which the body converts to L-arginine, an essential amino acid that helps relax blood vessels and improve circulation.

(2008). … Galdon et al. (2008) who measured the organic acid content in fresh onions reported that onions contain glutamic acid (325 Ϯ 133 mg/100 g), citric acid (48.5 Ϯ 24.1 mg/100 g), malic acid (43.6 Ϯ 10.4 mg/100 g) and oxalic acid (11.3 Ϯ 3.7 mg/100 g).

Watermelon is healthy because it’s full of lycopene – an antioxidant that helps break down harmful free-oxygen radicals. It prevents kidney injury and therefore, is a kidney-friendly food. How to eat watermelon: Keep it simple – just cut and serve! You can even have watermelon juice to refresh yourself instantly.
