Answer: 1.30
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
[tex]pH=-\log [H^+][/tex]
[tex]pH+pOH=14[/tex]
Given: 0.050 M [tex]HNO_3[/tex]
[tex]HNO_3\rightarrow H^++NO_3^-[/tex]
Concentration of [tex]H^+[/tex] = 0.050 M
[tex]pH=-log[0.050M][/tex]
[tex]pH=1.30[/tex]
Thus pH of 0.050 M of [tex]HNO_3[/tex] is 1.30.
