Question

Magnesium chloride solution coagulates the gold sol more readily than iron hydroxide sol ....
How??

Answer 1

@mayankdevnani pls...help

Answer 2

write the formula first

Answer 3

Kiska

Answer 4

dono ka

Answer 5

yaar! net bahut dheere chal raha h

Answer 6

Wohi toh

Answer 7

Hangout kholo

Answer 8

MgCl2 or Fe(oh)3

Answer 9

Remember :-
Greater is the charge on the ion causing greater coagulation !
OR
Greater is the charge,means greater is the COAGULATION POWER.

Answer 10

Pta h woh toh bt ek baat btao mgcl2 me dono hi charges h na Mg2+ b or Cl- b

Answer 11

Fe(OH)2 hoga

Answer 12

Toh dono hi charges coagulate kr skte h naa jse gold sol toh negative h toh it will be coagulated by Mg2+ n jo Fe(OH)3 h aoh positive h so by Cl- coagulate hoga

Answer 13

How do u know?

Answer 14

arrey ! generally yahi hota h

Answer 15

\[\large \bf Fe(OH)_2+H_2O \rightarrow Fe(OH)_3\]

Answer 16

so we take the simple case, Fe(OH)2

Answer 17

theek h yaha tak ?

Answer 18

General toh Fe(OH)3 dekha tha maine chlo koi ni isi me bta do

Answer 19

Yep aage bdho

Answer 20

agar tumme kisi ne acha padaya h toh, usne yeh bhi bataya hoga ki COAGULATION POWER IS DEPENDENT ON TWO FACTORS :-
1) CHARGE ON THE ION
2) HYDRATION ENERGY

Answer 21

Haan toh abb....

Answer 22

OR
NATURE OF ELECTROLYTE ALSO

Answer 23

Haan toh abb yeh kya ki jse mgcl2 pr mg2+ h charge toh gold sol coagulate hona h aasani se then cl- se jo coagulation honi h positive sol ki bcz charge jyada h mgcl2 me mg ka

Answer 24

sorry ! mere hisab se Fe(OH)3 hoga
you are right

Answer 25

Do tarike se answer aa jate h

Answer 26

1) Hydration Energy :-
Mg has very strong hydration energy.
So,it will coagulate more

Answer 27

2)Nature of Electrolyte :-
Since MgCl2 is strong electrolyte and Fe(OH)3 is weak electrolyte or insoluble.
So, MgCl2 more coagulates.

Answer 28

Kse pta ki hydration energy bhut jyada h
Woh toh bhut chote elements ki jyada hoti h

Answer 29

Like Be n Li

Answer 30

OR
i'll give you order of anions and cations for coagulation :-

Answer 31

Abb jyada kam kiske respect me bol re ho yeh b bta do...

Answer 32

arrey ! sami
voh baad ki baat h abhi hum difference pr dhyan de rahe h

Answer 33

Okay...

Answer 34

so Mg has more hydration energy than Fe+3

Answer 35

chalo aa gaya samaj main

Answer 36

Nahiiii !!!!!

Answer 37

kya

Answer 38

Smjh ni aaya

Answer 39

Yrr tum mgcl2 or fe(oh)3 me kyu compare kr re ho krna toh fe(oh)3 or gold sol me h naa vid respect to mgcl2

Answer 40

arrey ! satyanash

Answer 41

Haw......

Answer 42

Ase kyu bol re ho mjhe

Answer 43

as Gold sol is +ve sol, so we first compare anion power :-
it comes out to be same

Answer 44

then we move forward to cation power

Answer 45

Gold sol +ve h

Answer 46

haan Ag+

Answer 47

Arey ni negative h

Answer 48

Ase ni dekhte h. ...google kro

Answer 49

yep! sorry

Answer 50

i forgot metal are negative sols

Answer 51

I thought maine hi glt yaad kr liya h

Answer 52

nahi !

Answer 53

Abb kya kre. ...

Answer 54

toh theek h simple hydration energy check kar lo OR nature of electrolyte dekh lo

Answer 55

Hydration energy of Mg2+ with respect to ????

Answer 56

Gold k

Answer 57

Fe+3

Answer 58

arrey ! humme jo compounds given h usme difference dekh na h bas

Answer 59

Isse yeh kse prove hoga ki woh jyada gold sol ko kr raha h coagulate then fe(oh)3

Answer 60

bhai yeh factor h
factor affecting coagulation

Answer 61

itna mat deep jao, vaise humme sir ne bhi nahi bataya iska reason

Answer 62

Hamare sir ne toh pdhaya b ni h

Answer 63

ab kya kare ?

Answer 64

Dimag kharab ho gya ....kuch ques dekhke toh yeh log ase chap dete hi kyu h

Answer 65

Answer 66

lol

Answer 67

Koi expert ko bulao

Answer 68

kyun
samaj nahi aaya kya

Answer 69

Kahan aaya ...leave it...yrr...ghatiya concept h but....
