which one of the following solutions will contain the greatest strontium ion concentration: strontium carbonate solution (Ksp=5.6*106-10) or strontium fluoride solution (Ksp= 4.3*106-9)
Write down the equations:
Write down the formula for each reaction and equate it to the corresponding Ksp value.
Post what you did! :)
SrCO3(s) goes to equilibrium then Sr+2+ CO3-2
Ksp= conc of Sr+2 multiply by conc of CO3-25.6 *10^-5=X^2 then that equals to 2.5*10^-5=x
then For the second equation you do the same thing except different values of Ksp
Ksp=conc of Sr+2 multiplied by F-2 ^2
then, 4.3*10^-3=4X^3
equals to 1.0*10^-3=X
so the final answer is SrF2 has more concentration Sr+2 concentrations.
Well, while your final answer is good, I can't see where you got the numbers:
25.6*10^-5
I got![]()
Check your calculation well.
I made a mistake sorry, its suppose to be CO3-2 5.6 *10^-5=X^2 I forgot to be put space between Co3-2 so the final answer is 2.5*10 ^-5.
Oh, now I see it. The numbers just got messed up.
It's good, you got the correct answer :)
