Ihey buddy, please make separate threads for different qs
Ialso an attempt, a working of what your thoughts are, that helps a lot, share that as well,
!Think about ionic potential
Charge/radius factor
Charge/radius factor
!More ionic potential more polarizing power of cation more it steals electron density from the ligand and the ligand comes closer and the H in OH gains more delta positive and hence becomes easier to remove
SAnswer not matching with this method...I have tried it...the answer given is A...
!Weird
[Al(H2O)6]3+ should be the strongest
[Al(H2O)6]3+ should be the strongest
SBro but how will you know the radius??...you need to memorize it kya?
!Al3+ is bound to be smaller than Fe3+ bruv Fe bhot baad mein aata hai
SBut Zeff and sheilding effects are also there na...
!Decreases along the period increases down the group
SFor elements not for ions of that elements...
ISalt analysis padha hai kya? They all precipitate as hydroxides. Does this help?
IKsp value increases down the group
Ihydroxides - basically these ions.
S@iTeachChem still didn't understood why the answer is A

AThe rate law for a reaction between the substances A and B is given by Rate = k[A]^n[B]^m. On doubling the conc. of A and halving the conc. of B, the ratio of the new rate to the earlier rate of the reaction will be as:
CFor maths Q2, split 3 into 4-1 and 5 into 4+1, expand by binomial theorem
!2^n/2^m = 2^(n-m)
M250 will be the answer probably for maths one although chem one is out of my bounds
S500 ans given...
AA crystalline solid of a pure substance has a face-centred cubic structure with a cell edge of 400 pm. If the density of the substance in the crystal is 8g cm^-3, then the number of atoms present in 256g of the crystal is N×10^24. The value of N is:
