Calcium phosphate will precipitate out of blood plasma when calcium concentration in blood is 9.2mg/dL, and Ksp for calcium diphosphate is 8.64x10^(-13), what minimum concentration of diphospate results in precipitation?

1.6 ×M

Explanation:

for calcium diphosphate is 8.64x10^(-13)

concentration of the calcium cations = 2.2955 x 10^−3M

⇄ +

= ×

converting the concentration of the calcium cations from 9.2mg/dL to moles per liter , we get 2.2955 x M

=

=

     =1.6 ×M
