also an attempt, a working of what your thoughts are, that helps a lot, share that as well,
Think about ionic potential
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
Answer not matching with this method...I have tried it...the answer given is A...
Weird
[Al(H2O)6]3+ should be the strongest
Bro 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
But Zeff and sheilding effects are also there na...
Decreases along the period increases down the group
For elements not for ions of that elements...
Salt analysis padha hai kya? They all precipitate as hydroxides. Does this help?
Ksp value increases down the group
hydroxides - basically these ions.
@iTeachChem still didn't understood why the answer is A
The 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:
For maths Q2, split 3 into 4-1 and 5 into 4+1, expand by binomial theorem
2^n/2^m = 2^(n-m)
250 will be the answer probably for maths one although chem one is out of my bounds
500 ans given...
A 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:
