Submit What is the solubility of Cd3(POA) 2 in water? (Ksp of Cd3(PO4)2 is 2.5 x 10-33) | 1 2 3 +/- . 0 x100
vesna_86 [32]

<u>Answer:</u> The solubility of Cd_3(PO_4)_2 in water is 1.18\times 10^{-7}mol/L

<u>Explanation:</u>

The balanced equilibrium reaction for the ionization of cadmium phosphate follows:

Cd_3(PO_4)_2\rightleftharpoons 3Cd^{2+}+2PO_4^{3-}

                      3s       2s

The expression for solubility constant for this reaction will be:

K_{sp}=[Cd^{2+}]^3[PO_4^{3-}]^2

We are given:

K_{sp}=2.5\times 10^{-33}

Putting values in above equation, we get:

2.5\times 10^{-33}=(3s)^3\times (2s)^2\\\\2.5\times 10^{-33}=108s^5\\\\s=1.18\times 10^{-7}mol/L

Hence, the solubility of Cd_3(PO_4)_2 in water is 1.18\times 10^{-7}mol/L

Consider the molecules in the two proposed systems. How are they the same and how are they different?
allsm [11]

Molecules may be similar or different on the basis of size, shape, structure and chemical composition.

<h2>Similarities and differences</h2>

Two molecules can be considered similar or different on the basis of size, shape, structure and chemical composition. The molecules in the two proposed systems are consider the same when they are similar in size, shapes, structure and chemical composition.

While on the other hand, the molecules is considered different when they have different structure and chemical composition so we can say that molecules may be similar or different on the basis of size, shape, structure and chemical composition.

Calculate the molar mass for each of the following:
Mila [183]

Answer: a . 152g/mol  b. 102g/mol c. 183g/mol

Explanation:

By stating the atomic masses of each element in the questions, we have;

Fe= 56, S= 32, O= 16, Al = 27, C = 12, H =1 , N = 14, therefore

(a). FeSO4 =  56 + 32 + (16 x 4) =  152g/mol

(b). Al2O3 =  (27 x 2) + (16 x 3) = 102g/mol

(c). C7H5NO3S ( Saccharin, an artificial Sweetner) =

   (12 x 7) + (1 x 5) + 14 + (16 x 3) + 32 =  183g/mol
