ion is, 0.00371 M![[SO_4^{2-}]](/tpl/images/0550/0535/43b69.png)
ion.
will be:
![K_{sp}=[Ag^{+}]^2[SO_4^{2-}]](/tpl/images/0550/0535/80963.png)
![1.20\times 10^{-5}=(0.0300)^2\times [SO_4^{2-}]](/tpl/images/0550/0535/d8931.png)
![[SO_4^{2-}]=0.0133M](/tpl/images/0550/0535/cd404.png)
![K_{sp}=[Ca^{2+}][SO_4^{2-}]](/tpl/images/0550/0535/958f2.png)
![4.93\times 10^{-5}=[Ca^{2+}]\times (0.0133)](/tpl/images/0550/0535/7fa1a.png)
![[Ca^{2+}]=0.00371M](/tpl/images/0550/0535/7d329.png)
