Answer :
Correct Answer: 1.3
The pH of a solution is defined as the negative log of its hydrogen ion concentration.
The concentration of HI is 0.050 M. Since one molecule of H has one atom, the concentration of hydrogen ions in 0.050M HI will be 0.050 moles.
So,
[tex]pH=-log[ H^{+}] \\ \\ pH=-log(0.050) \\ \\ pH=1.3[/tex]
Therefore, the pH of 0.050M solution of HI will be 1.3.
