We’re being asked to determine the diagram that best represents an aqueous solution of NaF.
Ionic salts are made up of positively charged ion (cation) and a negatively charged ion (anion). To determine if the ionic salt would be acidic, basic, or neutral, we need to identify the acidity or basicity of the cation and anion.
• transition metal
▪ charge of +2 or higher → acidic
▪ less than +2 → neutral solution
• main group metal
Which of the following diagrams best represents an aqueous solution of NaF? The water molecules are not shown for clarity.
