A saturated solution of Ca_3 (PO_4) _2has [Ca^(+2) ]=2xx 10 ^(-8)M and

1.	A saturated solution of Ca_3 (PO_4) _2has [Ca^(+2) ]=2xx 10 ^(-8)M and [PO_4^(-3) ] =1.6 xx 10 ^(-5) M , K_(sp)"of "Ca_3(PO_4) _2 is
Answer» `3.2 XX 10^(_13) ` ` 3. 2 xx 10^(-34) ` ` 2.048 xx 10^(-33)` none of these SOLUTION :`Ca_3 (PO_4)hArr 3 Ca^(+2)+2PO_4^(_3)` ` K_(Sp)=[Ca^(+2)]^(3)[PO_4^(-3)]^(2) ` ` K_(Sp)=(2XX 10 ^(-8))^(3) (1.6 xx 10^(-5) ) ^(2) ` ` = 8 xx 10^(-24)xx 2.56 xx 10 ^(-10)=2.048 xx 10 ^(-33)`
