A) \[{{H}_{3}}P{{O}_{3}}\]
B) \[{{H}_{3}}P{{O}_{2}}\]
C) \[{{H}_{4}}{{P}_{2}}{{O}_{7}}\]
D) \[{{H}_{3}}P{{O}_{4}}\]
Correct Answer: A
Solution :
\[PC{{l}_{3}}\] and cold water reacts to produce orthophosphorous acid (phosphorous acid) \[{{H}_{3}}P{{O}_{3}}\]. \[PC{{l}_{3}}+3HOH\xrightarrow{{}}{{H}_{3}}P{{O}_{3}}+3HCl\]You need to login to perform this action.
