Question

What is the net ionic equation for CrCl3 + Ba(NO3)2

Answer 1

`3Ba^(2+)\text{ + 6Cl}^-\text{ }\rightarrow\text{ 3BaCl}_(2(s))`

Step-by-step explanation:

Here, we want to write the net ionic equation

We start by writing the complete equation of reaction:

`2CrCl_3\text{ + 3Ba\lparen NO}_3)\placeholder{⬚}_2\rightarrow3BaCl_(2(s))\text{ + 2Cr\lparen NO}_3)\placeholder{⬚}_3`

Now, we write out the ions as follows:

`2Cr^(3+)\text{ + 6Cl}^-\text{ + 3Ba}^(2+)\text{ + 3NO}_3^-\text{ }\rightarrow\text{ 3BaCl}_2\text{ + 2Cr}^(3+)\text{ + 3NO}_3^-`

The Chromium and Nitrate ions are spectator ions

Thus, we have:

`3Ba^(2+)\text{ + 6Cl}^-\text{ }\rightarrow\text{ 3BaCl}_2`
