The rain becomes acidic because carbondioxide, sulphurdioxide and nitrogendioxide which are released into the air as pollutants dissolve in rain drops to form carbonic acid, sulphuric nitric acid respectively. acid

Because co2 ,so2 and no2 which are released into air as pollutants dissolve in rain drops to form h2co3 ,h2so3 and hno3 respectively called acid rain 🌧️

[@GunjanSingh-lz3ez]

Sir you are best expantioner in the world 🙏🙏🙏 thank you for creating this video 🙏❤️❤️❤️

[@anishpradhan9852]

12:30 because CO2, SO2 and NO2 (which are released into air as pollutants) dissolve in rain drops to form H2CO3, H2SO3, and HNO3 respectively, called Acid rain.

[@nitinkumar7thd179]

[@_Aestheticx.693]

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.❤ Bhai I guess that was right answer

[@SakshamBhardwaj-xn1bg]

I am in class 10 but I am watching it for teachers day

[@tanusriagrawal4664]

10th mei aakar 7th class ka top8c nahi pata 😂😂😂😂😂

[@amitsingh-qq8qs]

Uncontaminated precipitation is naturally acidic. Water contains atmospheric gases as well as carbon dioxide, and when the carbon dioxide dissolves it forms carbonic acid, which makes the pH of normal rain about a 5.6 on the pH scale

[@ShiwanshMishra-b6x]

Sir aap bahut achaa explain karte ho shot video me hi itna achaa explanation wah sir Thankyou so much sir 😊

[@markanshumandayal0311]

It is caused by the large scale emission of acidic gases into the atmosphere from thermal power plants, industries and automobiles.

[@ZunairaMasoodZuni]

Thank you so muchh sir!! Your explanation helped me alot.

carbon dioxide (CO2) dissolves into it forming weak carbonic acid

[@RAMYTFF20]

Thank you sir💐🐼💗

[@Yo_boys]

Sir you are❤

[@rui_yt.]

sir you deserve 2 M subscribes.

[@RajivKumar-ew7tc]

acidic because carbon dioxide (CO2) dissolves into it forming weak carbonic acid.

[@lokeshsagtani5293]

when acids are realesed into air pollutants which dissolve in the rain........then when it rain it carrys acids with itv and then the rain is called acidic................

[@PinkiSaxena-d6e]

Thanks mannu bhaiya

[@ramparkash1700]

The rain containing excess of acids is called acidic rain. Sulphur dioxide, nitrogen dioxide, carbon dioxide are released into the air as pollutants during the burning of various types of fuels used in factories, homes and automobiles.These gases,released in the atmosphere, are fairly soluble in water.

[@neelamtadadikar4064]

The rain becames acidic because of carbondioxide, sulphur dioxide, nitrogen which are released into the air as pollutant and dissolve in rain drops.

[@pahadilover9062]

Acid rain is caused by a chemical reaction that begins when compound like sulfur dioxide and nitrogen oxides are released into the air . These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic
pollutants, is called acidic rain

[@pahadilover9062]

Sir is my answer is correct or not

[@pahadilover9062]

Ok wrong

[@aNiMa320]

Because when Co2 Dissolved in H2o Form Corbonic acid. Please tell me it is Right or wrong

[@prateekyadav7870]

Which acid in stomach help in digestion

[@spoiled_brat9118]

HcL

[@ruchibhardwaj9942]

Hydro cloric acid

[@aarnav_bj56]

The rain which contains acid is called acid rain, this acid in the rain comes from the gases realsed from factories, industries and vehicle fumes. Thus the acid rain occurs 😅

Sorry 7.49

[@navyapatel7821]

We do this in class with all acids and based

[@sunilmarathalab8636]

The the rain becomes acidic because carbon dioxide sulphuric dioxide and nitrogen dioxide which are released into the air as pollutants dissolve in airdrops to form carbonic acid sulphuric acid and nitric acid respectively

[@vijendrachauhan4907]

Thank you sir 😊

[@Sanaartstudio123]

Sir I have a doubt
If coffee is bitter in taste, so why it is called acidic....
Please help me to clear my doubt
Whatever I love your videos... ☺

[@youtubeyora123]

Coffee is acidic because it contains a number of acidic compounds and thats why it is called acidic in nature

[@kanchanghai6811]

Sar Jo aapane haldi Plus detergent kara tha vah base tha ya acid

[@Tochan_king_nishudeshwal]

Because of carbon dioxide, nitrogen they are released into atmosphere and dissolve in rain

Edit:1 like

[@aERRUPT]

ah as per you taught and as per the book the factories and many else realse acidic compunds ... which seeps to the seas and then evaporate and when the moisture along with the dust and acids mix it rains .. by becoming heavy and that ranin containing acid is the reason ...

[@nightgamer1697]

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

[@yuvrajcracker]

Science wali Mam 🤤🤤👄👄😂😂😂😂😂😂😂😂😂😂

[@dkgaming7814]

many factories release acid wastes in water bodies then that water evaporates and make clouds then the rain happens with acidic water so it is called acid rain

[@TIRUMALESWARARAO]

Hi gues

Sir ek question hai ki jab hamlog karela kathe hai to pet ma jalan nahi Hoti to agar hamlog eno pithe hai vo to meta meta sa hota hai

[@Rudrazzz]

Wo sweet in taste hai aur wo acid nahi hain hame ye pata chal gaya,par ek baat batao eno bhi soapy in touching hota hai 🧼 then base ka bhi ek property hay ki soapy on touching and then it is called as base

[@GurvinderSingh-qw6fp]

This happens due to excessive amount of sulfur dioxide and other gases
