Using the Ksp for calcium iodate hexahydrate, calculate the molarity of calcium ions. Using the Ksp for calcium iodate hexahydrate, calculate the molarity of iodide ions Ksp=7.10*10^-7. This is the reaction: Ca(IO3)2--->Ca+2IO3 I did an ice table, and using the Ksp of calcium iodate hexahydrate, I derived the solution as following: cuberoot(7.10*10^-7)/(4), the answer I got was .00561995. Since this is the value of S, twice that amount should be the Iodide ions, which is around .0112399. So did I...
