AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the process of breaking apart positive and negative ions of a compound when it is dissolved in a solution. 2. **Identifying the Process**: The process of breaking apart the ions in a solution is known as "dissociation." This is a key concept in chemistry, especially when discussing acids and bases. 3. **Examples of Dissociation**: - When hydrochloric acid (HCl) is dissolved in water, it dissociates into hydrogen ions (H⁺) and chloride ions (Cl⁻). - Similarly, sodium hydroxide (NaOH) dissociates into sodium ions (Na⁺) and hydroxide ions (OH⁻) when dissolved in water. 4. **Conclusion**: Based on the definition and examples provided, the correct term for the breaking apart of positive and negative ions of a compound in solution is "dissociation." **Final Answer**: The breaking apart of the positive and negative ions of a compound in solution is called **dissociation**. ---

The knowledge of valencies of various radicals helps us to write the formulae of chemical compounds. The total positive charge on positive ions ( cations ) is equal to the total negative charge on negative ions ( anions) in a molecule. Therefore, in writing the formula of a compound, the positive and negative ions are adjusted in such a way that the total number of positive charges of positive ions ( cations ) becomes equal to the total number of negative charges of negative ions ( anions) . There is another simple method for writing the formulae of ionic compounds. In this method, the valencies ( or positive or negative charges ) of the ions can be 'crossed over' to give subscripts. The purpose of crossing over of charges is to find the number of ions required to equalise the number of positive and negative charges. The formula of the sulphate of an element X is X_(2) ( SO_(4))_(3) . The formula of nitride of element X will be

    Any deviation from the perfectly ordered arrangement constitutes a defect or imperfection. The compounds in which the number of irregularity are present in the arrangement of atoms or ions are called atomic imperfections or point defects. These may be stochiometric or non - stoichlometric. Stoichiometric defects are further classified into Schottky defects in which number of positive and negative ions are missing in equal ratio and Frenkel defects in which an ion leaves its correct lattice sites and occupies on interstitial site. Schottky defect is more common in ionic compounds with high co-ordination number and where the size of positive and negative ions are almost equal, while in Frenkel defects are common in ionic compounds, which have low co-ordination number and in which there is large difference in size between positive and negative ions. When an ion leaves ir correct lattice and occupies interstital sites in its crystal lattice, it is called
