Name the following ionic compounds: (j) Ag 2 Cr 2 O 7 .

Hey everyone. Our question here wants us to determine the name for the following compound. As we can see right here, we have titanium which is a transition metal. So titanium does have more than one possible charge. So we can go ahead and label this as X. For now and for N. 03, this is our nitrate an ion. So it has a minus one charge. Looking at our compound, we can see that we have four of nitrate in order to compensate for titanium chart. So to determine titanium charge, we can go ahead and multiply for Times -1, which is nitrates charge. And we have our X. And we're going to add these two together, which will be equivalent to zero since we have A total charge of zero for our compound. And when we simplify this, we end up with x minus four equals zero, which gets us to X equals plus four. So this means titanium has a plus four charge. So the name of our compound is going to be titanium or with a roman numeral and a parentheses, since it is a transition metal and nitrate, since nitrate is our an ion. And this is going to be our final answer. So I hope this made sense. And let us know if you have any questions

Chapter 2, Problem 72j

Name the following ionic compounds: (j) Ag₂Cr₂O₇.

Verified step by step guidance

Step 1: Identify the cation and the anion in the compound. In Ag2Cr2O7, Ag is the cation and Cr2O7 is the anion.

Step 2: Name the cation first. The cation Ag is silver.

Step 3: Name the anion. The anion Cr2O7 is dichromate.

Step 4: Combine the names of the cation and anion. In this case, the name of the compound is Silver Dichromate.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Ionic Compounds

Ionic compounds are formed when atoms transfer electrons, resulting in the formation of positively charged cations and negatively charged anions. These oppositely charged ions attract each other, creating a stable compound. Understanding the nature of ionic bonds is essential for naming and writing formulas for these compounds.

Nomenclature of Ionic Compounds

The nomenclature of ionic compounds involves specific rules for naming the cations and anions. Cations, typically metal ions, retain their elemental name, while anions often have their names modified, usually by adding an '-ide' suffix or using a specific name for polyatomic ions. Familiarity with these naming conventions is crucial for accurately identifying compounds.

Polyatomic Ions

Polyatomic ions are ions composed of two or more atoms that are covalently bonded and carry a net charge. Common examples include sulfate (SO4^2-) and chromate (CrO4^2-). Recognizing polyatomic ions and their charges is vital for correctly naming compounds that contain them, such as Ag2Cr2O7, which includes the dichromate ion (Cr2O7^2-).
