TYPE OF TITRATION I VERY EASY WAY I HINDI

- Complexometric titrations are of 4 types:
1. Direct Titration: It is the simplest and the most convenient method used in chelometry. In this method, the standard chelon solution is added to the metal ion solution until the endpoint is detected. This method is analogous to simple acid-base titrations. E.g.-calcium gluconate injection, calcium lactate tablets, and compound sodium lactate injection for the assay of calcium chloride (CaCl2.6H2O).
2. Back Titration: In this method, excess of a standard EDTA solution is added to the metal solution, which is to be analyzed, and the excess is back titrated with a standard solution of a second metal ion. E.g. - Determination of Mn. This metal cannot be directly titrated with EDTA because of precipitation of Mn(OH)2. An excess of a known volume of EDTA is added to an acidic solution of Mn salt and then ammonia buffer is used to adjust the pH to 10 and the excess EDTA remaining after chelation, is back titrated with a standard Zn solution kept in burette using Eriochrome Black T as an indicator. This method is analogous to the back titration method in acidimetry. e.g.- ZnO
3. Replacement Titration: In this method, the metal, which is to be analyzed, displaces quantitatively the metal from the complex. When direct or back titrations do not give sharp endpoints, the metal may be determined by the displacement of an equivalent amount of Mg or Zn from a less stable EDTA complex.
4. Indirect Titration: This is also known as Alkalimetric titration. It is used for the determination of ions such as anions, which do not react with EDTA chelate. Protons from disodium EDTA are displaced by heavy metal and titrated with sodium alkali.

sir, we can understand better from your videos than physical classess, please keep making more phamacy videos . thankyou
baba g .. Bht shukria .. Mjy bht mushkil pesh aa rhi thi smjhny m
Thank you sir.. very helpful topic 🙏
Excellent method for understanding
Thank you sir aapka thumbnail dekh k laga nahi tha aap samjha paoge but you proved the idiom don't judge a book by it's cover
Am grateful, viva would be a disaster otherwise. lots of respect from Pakistan, proff :)
sir it's really helpful for me
Sir ur videos r awesome 😊helps to clear me many topics 😊thanku so much...
Really great sir❤️
Nice video bahut useful hai sir
Tnq so much sir your video is very very helpful
This video very helpful sir 👍
For me ☺
Thank you so much sir 👍
Sir your understating is tooooo gooood
great explanation sir
Thank you sir love form up❤️
Thanks a lot sir I already watched many videos but I didn't understand this 🥳
Sir direct titrations mai bhi to hum standard ke through Hi unknown sample ki conc. Ka Pta kr krte
So what is the difference between back and direct titrations
Sir! please differentiate b/w back,indirect and replacement titration?
Excellent sir
Very nyc sir
Mashaallah......wonderful
You are great sir!¡!!
Excellent
Sir you are great
Thanku soooooo much sir ..ur explanation is very clear and every one can understand clearly
Sir create video on polargraphy and potentiometry
👍👍very helpful
Thank you so much sir
Great sir
Tum jio hajaro saal sir
thnku so much sir 🔥❣️
Kamal ha method
Sir which chemical we take in the burette in indirect titration???
Sir aapny bohat complicated krdya still back titration asani sy smjhaya jaskta tha aap example ko he smjhaney mein lg gye. Generally btatey tou shayad aajata smjh hmein
Thanks sir great
Thanks helped a lot might give 5mks in exam
Osm sir 👌
Great
Nice 👍
Thank u very much sir
Nice vedio sir
Plz......discussed interfacing hplc with MS for m.sc chemistry 2
Sir back and indirect titration ko compare krke btaiye like difference between
Thank you💖
Sir mujhe he nahi pata chala ki replacement titration me Mn-EDTA or Mg-EDTA ak sath kaise hote he?
great
Sir ek bada question hai mera about back titration how can i take a help from u .
Thanks sir ❤️
Extraordinary
Think you sir
Thank you
Nice sir
Thanks
Thanks Sir
Sir indirect ka thoda vsa example deke explain kro na plz.... Likewise the example u give of a room and that group A group B
Thanks u so much
Sir aap tshirts kahan se buy karte ho?
Video on combined Electrode
Tq so much sir
How to calculate/find percentage concentration of liquid NaOH v/v?
Sir back titration ki kaya example dia sir masa aayega
Sir please baye company me titration ka use kaise kr , wse to me college me kiya tha but waha to concentrate ko pta lgte the but yaha kaise kre👏
Sir app video leacture bana ye
Analysis remeaning
Nice
Thank you really helpful
You're welcome!
Sir ji what is the oos and oot
Sir alkalimetric titration jo he usme (MY)n-4 kese aya
Sir aap ye chapter ke important question ke video banasakte hai ?
How many year teaching & research experience you have that you have mention Prof in your name...
Suberb
❤thnkooooo sir
Sir, plz provide notes also..
Jo aap type btaye hai vo hote hai to redox, precipitation ,complexometry ye kya hai fir
Sir isske note kha mileage...
Replacement titration theek se samjha do sir
Tq sir
Nahb solution of pH topic is very hard sir aspe video banaiye
👍👍
Sir ji indicater samaje nahi a raha he
Sir I'm from pakistan kindly make video on titration
Sir please create a video on cunductometry titration
🙏🙏
Sir replacement titration me direct Mn -EDTA strong complex hai ,to keu me Mg add karu
Ha jn mangnese bana rha h to magnesium ko kyu karo add🙄
Yaar shit koi to iska jawaab do 😭
How Can I cotact to u
Sir theory bi bta diya kro
Mp residents generally pronounce back as Beck
Analysis ka all videos chahie sar 1st sem ka
Sir me HPLC ka advance course karna chahta hu
Sir or video bhej do
Y hota h
Acid base T
Redox T
Complaxmatric T
........
Same back titration hai
Bata digiye sir
Ostwald methods par video sir
Theories of INDICATORS I all ready made for it.
thank you sir ap online class kar tehe kys I am working in pharma company in quality control department
A d t a kya he
Help me sir 🙏
Back mai magnese bana to rha h complex 🙄
I am trying really hard to understand Proffesor due to the accent, if an Indian firiend could help putting subtitles to this I would appreciate it
Where are you from Jose

Indirect titration ma bhi to metal determination hai
Somendra Tewari yes
Note toh dijiya
