Chapter 10, Problem 81e
Identify each of the following as an acid, base, or salt, and give its name:
e. H2CO3
Verified step by step guidance1
Step 1: Recognize the chemical formula H₂CO₃. This is a molecular compound composed of hydrogen (H), carbon (C), and oxygen (O).
Step 2: Recall that acids typically have hydrogen atoms that can dissociate in water to produce H⁺ ions. H₂CO₃ contains hydrogen atoms that can ionize, which is a characteristic of acids.
Step 3: Identify the polyatomic ion present in the compound. The CO₃ portion represents the carbonate ion (CO₃²⁻). When combined with hydrogen, it forms carbonic acid.
Step 4: Name the compound. The systematic name for H₂CO₃ is carbonic acid. It is classified as an acid because it can donate H⁺ ions in aqueous solutions.
Step 5: Conclude that H₂CO₃ is an acid and its name is carbonic acid.
