Answer: An ionic bond is a bond that forms between ions with opposite charges.
Explanation:
A chemical bond formed by the transfer of electrons from one atom to another is called an ionic bond.
For example, sodium has electronic distribution as 2, 8, 1 and chlorine has electronic distribution as 2, 8, 7.
In order to attain stability, sodium needs to lose 1 electron and chlorine needs to gain one electron. Therefore, sodium will transfer its one valence electron (forming ion) to chlorine atom (forming
ion) which leads to the formation of NaCl compound.
Thus, we can conclude that an ionic bond is a bond that forms between ions with opposite charges.
This is an incomplete question, here is a complete question.
A solution containing CaCl₂ is mixed with a solution of Li₂C₂O₄ to form a solution that is 3.5 × 10⁻⁴ M in calcium ion and 2.33 × 10⁻⁴ M in oxalate ion. What will happen once these solutions are mixed? Ksp (CaC₂O₄) = 2.3 × 10⁻⁹
A. Nothing will happen since both calcium chloride and lithium oxalate are soluble compounds.
B. Nothing will happen Ksp > Q for all possible precipitants.
C. A precipitate will form as calcium oxalate is not soluble to any extent.
D. A precipitate will form since Q > Ksp for calcium oxalate.
Answer : The correct option is, (D) A precipitate will form since Q > Ksp for calcium oxalate.
Explanation :
Concentration of =
Concentration of =
The equilibrium chemical reaction will be:
The solubility constant expression for this reaction is:
Now we have to calculate the ionic product for calcium oxalate.
From this we conclude that, that means a white solid precipitate of calcium oxalate will be formed when the solutions are mixed.
Hence, the correct option is, (D)
