Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge.
<u>Answer:</u> The solubility product of magnesium phosphate tribasic is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:
Given mass of magnesium phosphate = 1.24 g
Molar mass of magnesium phosphate = 262.85 g/mol
Volume of solution = 1 L
Putting values in above equation, we get:
The equation for the ionization of the magnesium phosphate is given as:
Expression for the solubility product of 
will be:
![K_{sp}=[Mg^{2+}]^3[PO_4^{3-}]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BMg%5E%7B2%2B%7D%5D%5E3%5BPO_4%5E%7B3-%7D%5D%5E2)
We are given:
![[Mg^{2+}]=(3\times 4.72\times 10^{-3})=1.416\times 10^{-2}M](https://tex.z-dn.net/?f=%5BMg%5E%7B2%2B%7D%5D%3D%283%5Ctimes%204.72%5Ctimes%2010%5E%7B-3%7D%29%3D1.416%5Ctimes%2010%5E%7B-2%7DM)
![[PO_4^{3-}]=(2\times 4.72\times 10^{-3})=9.44\times 10^{-3}M](https://tex.z-dn.net/?f=%5BPO_4%5E%7B3-%7D%5D%3D%282%5Ctimes%204.72%5Ctimes%2010%5E%7B-3%7D%29%3D9.44%5Ctimes%2010%5E%7B-3%7DM)
Putting values in above expression, we get:
Hence, the solubility product of magnesium phosphate tribasic is
It introduces a diverse array of bacteria, algae, and invertebrates to the closed marine environment and functions as a superior biological filter
