Sir provide us more lecture your lecture are super and easy to understand thanks sir for the good quality education 😇😇

[@SonuSharma-gu1rr]

Way of explanation was superb bro, bahut acchee se topic ko samjha bhai. Thank you

[@user-wj8lp2sd9q]

Normality:- It can be defined as the gram equivalent weight of solute to the volume of solution in 1 L. Wher gram equivalent weight=molecular weight by acidity and basity

[@anii_21]

👏

[@Studentofficial18]

Hii,, brother

[@Studentofficial18]

I am also b pharma's student,, you can help me that b pharma is easy and hard plese bro quickly reply me... Thank you

[@neetaspirant2271]

Jaise aap ki video ka first part complete Kiya waise he second part upload kar diya aap ne thanks sir 😅

[@apoorvagupta6075]

From Which college are studying

[@naziyasharafat9949]

Thank you sir ❤❤❤ for you I understand easily ❤❤

[@Doremon.telivision]

Thanks sir for your wonderful teaching forms with note...

[@Nehakhatoon-xk8dj]

Thank you so much sir... Very easy to understand ❤

[@priyadarshini9512]

NORMALITY is defined as the gram equivalent weight of solute to volume of solution in 1L where as GRAM EQ. WEIGHT is molecular weight divided by acidity or basicity ❤

[@SMvideos352]

Thank uhh so much sir for sharing your knowledge in simple way🥰

[@gautam8757]

Aapke pass notes semester 1 ka h

[@axx9099]

Equivalent weight=molecular weight/acidity or basicity
No.of gram equivalent=Given weight/equivalent weight
Normality=No. of gram equivalent/volume of solution (l)

[@sapanmondal3]

The normality of a solution is defined as no of gram equivalent of solute present per litre of solution.
It is denoted by N
Normality=(gram equivalent of solute)/(volume of solution in litre)

[@user-sb2nr7vp4s]

Thanks sir
Your lecture is very helpful ❤❤❤

[@wizardofwcc3768]

Normality - it is also known as normal
Its denoted by 'N'
It's is defined as the gram of equivalent dissolved in per litre of solution

[@user-ph8ty1dl6t]

Thank sir i love lec u teach so good

[@user-zr9cz7lj7q]

Normality : It is defined as no. of gram equivalent of solute dissolved in one litre of solution.
Unit : gram per litre --> g/L
Formula :
N = no. of gram equivalent of solute / volume of solution (in litres).
No. of Gram Equivalent of Solute = Given Mass / Equivalent Weight
Equivalent Weight = Molecular mass / Acidity of Base or Basicity of an Acid.
Eg. Acidity of NaOH = 1
Basicity of H2SO4 = 2.

[@naseemakhtar78692]

The number of gram equivalent weight of solute is dissolved in (1litre) of solvent/solution are known as Normality. Equivalent weight=Molecular weight/Acidity or basicity.

[@user-tp7px1uf1u]

You are gr8 sir thank you so much ❤❤❤❤❤❤❤❤❤❤❤❤❤

[@PuneetMishra-eu4bo]

[@bhanwarlalsiyagbirloka1024]

Normality:- also known as normal concentration and denoted by capital 'N'
:- It is diffaind as, no. Of gram equivalent of solut dissolved in one litter of solution.

[@Aditya-tw9jy]

Normality is defined as the number of gram equivalent of solute per liter of solution
Gram equivalent weight= moleculer weight/acidity or basicity
No of gram equivalent= weight of solute/gram equivalent weight

[@bakchod_friends420]

Sir ji tussi great ho

[@sohravkhan3730]

Thankyou sir

[@vkumar_y-fm7wf]

Normality : It is defined as , no.of gram equivalent of solute dissolve in 1 litre of solution . It is also known as normal concentration.

[@shruti7052]

Sir gives important topics

[@musical_adhik]

Best ❤

[@pranjalmaurya8154]

No of gram equivalent of solute dissolve in one liter of solution is known as Normality
Formula N=no of gm eq of solute /volume of solution

[@mahavirsharma6612]

Normality- it is also known as normal concentration and it is denoted at "N"
2) it is defined as numbers of gram equivalence of solute dissolved in per litre of solution.
N= no of gram equivalence \ volume of soltuon (ml)
Am i right

[@Gaminggyani70]

It can be define as the gram equivalent weight of solute to the volume of solution in 1 litre .

[@hgvv178]

Thnku sir for this lecture

[@kartarsaini166]

Normality =the normality is a solution is that the moles of react unit per lit. 1 moll react unit is called equivalent

[@sejalmahamune3551]

gram eqvalent weight=molecular weight/acidity or basicity

[@user-jl2xt2hk9y]

Normality is also known as normal concentration
It is denoted by N
It is define as no of grams of equivalent of solute dissolve in 1 litre of solution
N= gram equivalent weight of solute/volume solution ( 1 litre)

[@njodrik]

Normality : It is a way to express conc. of solute wrt the solution.
- It is "Number of Gram Equivalent" in 1 L Volume of the Solution
i.e. N = Number of Gram Eq. / Volume of Solution (in L)
- No. of Gram Eq. = Weight of the Substance / Equivalent weight
- Equivalent Weight = Molecular Weight / X (Acidity or Basicity)

[@theheavenaround3150]

normality also known as normal concentration, denoted by capital N the no. of gram equivalent mass in one liter of solution

[@MAXforyou20]

Normality :-
It is defined as, number of gram equivalent of solut dissolve per litre of solution.

[@mrTam092]

NORMALITY :- Normality is define as the no. gram equavalant waight of solute present in one liter of the solution.

[@kingofdevil9470]
