If x represents the molar solubility of b a 3 ( p o 4 ) 2 , what is the correct equation for the k s p ?
AnnyKZ [126]

The molar solubility of Ba₃(PO₄)₂ is its concentration of pure substance

The correct equation for the ksp is Ksp = 6x⁵

<h3>How to determine the equation of ksp?</h3>

Start by writing the reaction for the solution of Barium phosphate

Ba₃(PO₄)₂  ⇌3Ba²⁺ +2PO₄³⁻

Next, we make an ICE chart

Let "x" be the molar solubility of Barium phosphate

          Ba₃(PO₄)₂(s)  ⇌3Ba²⁺ +2PO₄³⁻

I                                 0                  0

C                              +3x               +2x

E                                3x³                 2x²

Lastly, we write the expression for the solubility product constant (Ksp)

This is represented as:

Ksp = [3Ba²⁺] × [2PO₄³⁻]²

Ksp = 3x³ × 2x²

Evaluate the product

Ksp = 6x⁵

Hence, the correct equation for the ksp is Ksp = 6x⁵

Need help with math problem if do get 5 star
Luda [366]

Answer:

S

Step-by-step explanation:

The first co-ordinate (1) will be on the x-axis, so we go across to the first square. Then you go 3 up the y-axis because of the second co-ordinate, and that is where S is.

Hope this helps!
