B should be 20 because only 1 oxygen goes into water
C is hydrogen because 2 hydrogens go into each water
Can't read anything beyond c
Answer : The pH of calcium acetate solution will be 9.38.
Explanation : When calcium acetate dissocates completely in solution to form Calcium(+2) ions and two acetate ions, this gives the acetate ion concentration as
(2 X 0.51 M) = 1.02 M
Acetate ion then hydrolyzes as follows;
:
Now, Kb will be = ![[HC_{2}H_{2}O_{2}] [OH^{-}]](https://tex.z-dn.net/?f=%20%5BHC_%7B2%7DH_%7B2%7DO_%7B2%7D%5D%20%20%5BOH%5E%7B-%7D%5D)
/ ![[C_{2}H_{3}O_{2}^{-}]](https://tex.z-dn.net/?f=%5BC_%7B2%7DH_%7B3%7DO_%7B2%7D%5E%7B-%7D%5D%20)
= Kw / Ka
= 1 x 
/ 1.8 x 
= 5.6 × 
![[OH^{-}]](https://tex.z-dn.net/?f=%20%5BOH%5E%7B-%7D%5D%20)
= 2.4 ×
Now, we know , pOH = -log = 4.62
So, the pH = 14 - pOH = 14 - 4.62 = 9.38
An ion-dipole interaction is the result of an electrostatic interaction between a charged ion and a molecule that has a dipole. It is an attractive force that is commonly found in solutions, especially ionic compounds dissolved in polar liquids. A cation can attract the partially negative end of a neutral polar molecule, while an anion attracts the positive end of a polar molecule. Ion-dipole attractions become stronger as the charge on the ion increases or as the magnitude of the dipole of the polar molecule increases.
This force of attraction is between an ion and a charge , it is weaker force than covalent bond and ionic bond . EX - The ion dipole interaction takes place between water and sodium ion , in it there is a small charge on oxygen molecule in water which is attracted by sodium charge .
Most commonly found in solutions. Especially important for solutions of ionic compounds in polar liquids.
A positive ion (cation) attracts the partially negative end of a neutral polar molecule.
