Thank you very much indeed!
looking back I think I was confused initially by the way it was given,
Ni 2+ + 2H2O <-> Ni(OH)2 (s) + 2H+
and forgot to go to the definition of the solubility product. this is a good lesson learned.
Refer to the textbook page attached.
Ni(OH)2 = Ni2+ + 2(OH)-
Ks = [Ni]2+ x (OH)-^2 = 10^(-12.73)
Ni+ ranges from 1 to 0.01M, so OH- can be calculated accordingly. Is this right now?
Thank you for pointing out. the formula should've been:
Ksp= [Ni(OH)2] * [H+]^2/[Ni+] = 10^(-12.73)
I still am not clear what to do next. Could you please advise?
Homework Statement
Hey guys,
I am preparing a technical exam and am facing an exam problem below:
Ni is electrodeposited from an aqueous sulphate solution that has a composition that fluctuates from 1 to 0.01M due to changes in the feed composition of the process.
a) what is the pH range that...
I did some search but with not much luck. Thanks for the link provided which is helpful but not addressing the question. I am preparing for an exam for the course of Fracture and Failure Analysis and this is one of the past questions that I have seen.
Why are materials whose yield stresses are highly strain-rate dependent
more susceptible to brittle fracture than those materials whose yield stresses
do not exhibit marked strain-rate dependence
