yeah that's it, 1.78x10^-4 is the same as 10^-3.75! Thank you loads for the help, just need to revise a ton of other stuff for this exam! Thanks again!

think I'm starting to understand a bit better now! can i now rearrange Ksp=[Mg^2+]^2 to SQRT Ksp=[Mg^2+] or SQRT10^-7.5 in which case the concentration of the ions will be 10^-3.75 ??

cheers for the reply hootenanny, i wrote the initial question in a bit of a hurry yesterday and forgot to say i have NO idead what to do with the info! I know the relative concentrations of the ions will be equal and think that the dissociation is MgCO3 <=> Mg^2+ & CO3^2- Think the expression...

Hi need a bit of help with a question! the solubility product of magnesium carbonate is 10^ -7.5. Calculate the concentration of Mg2+ and CO3 2- expected in a saturated solution assuming activity of both ions is 1.0 cheers in advance!

woo hoo i got something right! borek i think it was the way i wrote the reactions out that made you think they were unbalanced! Next time i'll do a better job! Thanks for all your help guys, now i can start worrying about all the essays I've just been set! (anyone fancy doing those for me...

thanks for the help guys, i got some more help from my teacher the other day and kind of got it sussed! although i am now a little confused about the ratios. I've worked out that the ratio of IO3:S2O3 is 1:6 not 1:5! are you certain of this nicholas as it will make a big difference to my...

totally stuck! hey guys and girls, I'm having some serious problems with this redox reaction titration thing i just did! Basically i titrated a sodium thiosulphate solution with potasium iodate(v), sulphuric acid, potassium iodide and some starch. I've worked out the molarity of my sodium...
