🔴 NCERT Class 10 Science Chapter 2 is all about acids, bases and salts. In your previous classes, you have learned that the sour and bitter tastes of food are due to acids and bases, respectively, present in them. We all know that acids are sour in taste and change the colour of blue litmus to red, whereas, bases are bitter and change the colour of the red litmus to blue. In this chapter, we will study the reactions of acids and bases, how acids and bases cancel out each other’s effects and many more interesting things that we use in our day-to-day life. You will get to understand the chemical properties of acids and bases, how acids and bases react with metals, how do metal carbonates and metal hydrogen carbonates react with acids, how do acids and bases react with each other, reaction of metallic oxides with acids and reaction of a non-metallic oxide with base explained with suitable examples and various chemical reactions.
🔴 The chapter then explains what all acids and bases have in common with a suitable example which gives the conclusion that acid solution in water conducts electricity. Students get to learn various experiments on what happens to acid or a base in a water solution and how strong are acid or base solutions by making use of universal indicator. Along with it, you will get to learn about the importance of pH in everyday life. The chapter ends with explaining in detail about salt preparation, properties and its uses.
🔴 These videos are prepared by our expert faculties to help students in their board exam preparations. They clear concepts of NCERT for Maths so as to aid the students to solve the problems easily. They also focus on problem solving in such a way that it is easy to understand for the students. They provide a detailed and step-wise explanation of each concept given in the exercises of NCERT books.

[@Jayvyas01]

Why the Na (sodium) is not combined by cathode reaction? But cl (clorin) is combined with anode reaction? Please answer teacher 👩‍🏫‍

[@Jayvyas01]

Supper question?

[@musharrafali8560]

Avanti mam aap ne bahut ache se. Teach kra is process ko

[@SajidKhan-gz9yr]

Is this right that Negatively charged at cathode Positively charged at anode

[@preetiyogaa]

perhaps cz unlike charges attract each other

[@Anand_Kumar88]

Yes It's right. May you confused

[@asadkamboh7663]

bhai battery k poles ko ulta kr do ap ki bat thk ho jay gi

[@ChemistrywithKamranchaudhary]

nahi bilkul Nahin Hamein Yahi padhaya Jata Hai Ke anode positively charged hota hai aur negatively charged cathode hota hai lekin Yeh definition galat hai Hamesha Ham anode or cathode ko Is Tarah define Karte Hain Ki anode wo electrode hota hai jaha par oxidation ho rahi hoti hai aur cathode wo electrode hota hai jaha par reduction ho rahi hoti hai

[@kishorilal5573]

Thank you mam for clear my doubts

[@Lt.Brahman]

Mam I have a doubt 2Cl(aq) - 2e > 2Cl Isme mam chlorine ke atom ko apni orbit fill karne ke leye 2 electron chaiye to 2Cl + 2e hona chahiye fir in done ke beech mein minus ka sign kyu aaya

[@payalkumari7711]

Mam your explanation is too good

Finally I clear my dout thank you thank you so much didi😀😀😀😀

[@nationfirst6457]

Plzzzz reply... How to make any metal for anode and cathode... Means here we are using two iron metal for anode and cathode but how to know metal is anode or cathode

[@ChemistrywithKamranchaudhary]

ye 1 electrolytic cell Mein Hum kaam kar rahe hote hain electrolytic cell Mein Hum electrical energy ko chemical energy Mein convert karte hain SO Ham electrolytic cell mein battery use karte hain As a energy source so electrolytic cell ke liye aap keh sakte hain Ke Jo electrode battery ke positive terminal ke sath attach hoga woh anode Hoga aur jo electrode battery ke negative terminal ke sath attach Hoga woh cathode hoga

[@madhaviabhijeet8926]

the metal stick near negative end(smaller line) in anode(positive) and the other one is cathode(positive). that's how i remember it.

[@khushbupatne9725]

Mam aap bhot achha samjhate ho 😍 aaj mera exam h science ka mujhe chlor-alkali process ko samjh ne problem hori thi ab bhot achhe se mind me beth gya sub thank you so much mam ❤️

[@annu9996]

Fabulous Explained Mam...The way u teach is very superb❤️❤️.. And finally now my doubt is clear 😁😁

[@examcompetitor4793]

Who it is possible to form sodium hydroxide...how Na+ is forming bond with OH- ..after na losing their outermost electron

[@deepabhanushali6790]

Thank you ma'am for your excellent explanation

[@kittujasthi88]

Yo, did she swap the reactions the reactions at cathode with the reactions at anode ?

[@jd_edits569]

23-24 here

[@ant-.-]

Wow kitne aache se samjaya❤❤❤

[@user-cz5qp6hu7e]

Best Explanation Mam..Even my school teacher also didn't say this much clearly..Thank you so much mam..💫✨💗🥰☺️❤️

[@awaisjabbar5013]

Mam you are great, You solve my confusion

[@salmaparveen9907]

Mam sodium is highly reactive but it why it didn't go to cathode to fill its last shell similarly why OH ions didn't go to anode to lose electron?

[@amritamishra7707]

Thank u so much...mam..mera sara doubt clear ho gya..ab me ..mere frnd logo ko smjhane jaungi..for revise..thank u thank u...so much..😀😀

[@sumeerkhajuria5511]

fantastic explanation and very attractive way understanding concepts

[@user-ww4kn4jv1p]

My science exam is in 6 hours and this made this topic so clear. Thank you so much

[@simransharma3507]

Very well explained mam

[@PJ-Eachother3]

Mam i have dout was that sodium was less reactive campare to hydrogen and in reactivity series it is also menstion.

[@ChemistrywithKamranchaudhary]

Agar Hum sodium metal Ki Baat Karen to wo more reactive Hoti Hai hydrogen se lekin Yahan Par Hamare Paas sodium ka ion maujood hai so sodium ka ion jo hoga woh less reactive hoga H positive ions sy.. is concept ko samajhne ke liye aapko reactivity series ka idea Hona chahie

[@raginisinha3003]

Finally 🥳🥳 There's someone who understand us this topic

[@sarangabbasi2560]

2024-2025 attandance 😊

[@bhavygaming6651]

Great explanation thank you so much ma'am

[@a.k2767]

Mam why sodium will not go if it is very reactive. What is the real reason behind it

[@aaryanmaurya07]

Because of electrochemical series

[@saumyayay]

thanks a lot, you explained this very clearly!

[@lenovo6739]

Mam at which electrode NaOH is formed? And why?

[@indianlover4807]

Cathode

[@bhattifruitfarm9206]

Very good teaching process

[@user-xb2xp5or4k]

Anyone from 2024-25 batch 😊😊??

[@avantikanautiyal_]

very well explained!!... Understood chlor alkali process clearly..thanks a lot 😊🤗

[@anitcreations2076]

Mam keep uploading videos to help us to understand the concept clearly ....

[@sagnikpall]

If h gets electrons it won't be diatomic it will become monowtomic which is not possible

[@bihariagarwal7447]

Maam you are wonderful The explanation is really great I don't have words to describe

[@Siddharth_10_]

❤❤❤ what a great explanation! 😊😊

[@shubhiagarwal5762]

Thank you ma'am for this good explanation ❤️ but i have a doubt i just want to clear if cathode is negatively charge or positively...as i know it is positively charged...please make my this doubt clear!!!

[@vickyvm6]

Avanti, hydrogen gas first produced on cathode due to lower discharge potential of H+ as compared to sodium ion. Also same for anodic reaction :):)

[@aryankumarsrivastava8904]

Sorry but I don't think that you are right about saying that we cannot obtain any by reversing the process that is, by mixing NaCl and water.if acid and base react with each other to form salt and water we can get the same acid and base by mixing the salt and water and that process is called as salt hydrolysis

[@parmeetsingh6855]

Thanks mam .such great explation
