## Step 1<br />The problem is asking about the state of ions when they are completely dissociated in aqueous solutions. <br /><br />## Step 2<br />When ions are completely dissociated in aqueous solutions, they are surrounded by a hydration shell. This is because the water molecules surround the ions, forming a hydration shell.<br /><br />## Step 3<br />The hydration shell is a layer of water molecules that surround the ion. This layer is formed due to the polar nature of water molecules, which allows them to surround the ion.<br /><br />## Step 4<br />The hydration shell is not a salvation shell, nor is it a ghost in the shell. It is a hydration shell.
