The correct Answer is:
To determine the classification of the acid \( H_3PO_3 \), we can follow these steps: ### Step 1: Identify the formula of the acid The given acid is \( H_3PO_3 \). ### Step 2: Analyze the structure of the acid The structure of \( H_3PO_3 \) can be represented as follows: - It contains one phosphorus (P) atom. - It has three hydrogen (H) atoms. - It has three oxygen (O) atoms. ### Step 3: Determine the number of ionizable hydrogen ions To classify the acid, we need to identify how many hydrogen ions (H⁺) can be released when the acid dissociates in water. In \( H_3PO_3 \): - Two of the hydrogen atoms are bonded to oxygen (as hydroxyl groups, -OH). - One hydrogen atom is directly bonded to phosphorus. This means that \( H_3PO_3 \) can donate two protons (H⁺ ions) when it dissociates. ### Step 4: Classify the acid based on the number of ionizable protons Since \( H_3PO_3 \) can donate two protons, it is classified as a dibasic acid. ### Conclusion Thus, \( H_3PO_3 \) is a dibasic acid. ---
