name the acid: h₃po₃\nhydrophosphoric acid\nphosphorous acid\nphosphoric hydroxide\nphosphoric acid
Answer
# Answer:
B. phosphorous acid
# Explanation:
## Step1: Recall acid - naming rules
For oxy - acids with the general formula \(H_aX_bO_c\), if the central atom \(X\) has a lower oxidation state, the acid name has the suffix “-ous”. In \(H_3PO_3\), the oxidation state of phosphorus (\(P\)) is + 3. Phosphoric acid (\(H_3PO_4\)) has \(P\) in a + 5 oxidation state. Hydrophosphoric acid is \(PH_3\) which is not an oxy - acid. Phosphoric hydroxide is not a correct name for \(H_3PO_3\). So \(H_3PO_3\) is named phosphorous acid.
