We’re being asked to determine if the salt solutions are acidic (A), basic (B), or neutral (N).
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
Would the following salt solutions be acidic (A), basic (B), or neutral (N)? (hint: Think of the reactions with water)
A. Li2CO3 - Neutral, Ba(ClO4)2 - Neutral
B. Li2CO3 - Basic, Ba(ClO4)2 - Basic
C. Li2CO3 - Acidic, Ba(ClO4)2 - Neutral
D. Li2CO3 - Basic, Ba(ClO4)2 - Neutral
E. Li2CO3 - Basic, Ba(ClO4)2 - Acidic
