Answer:
6 is the pH of the diluted solution.
Explanation:
The pH of the solution = 5.0
Concentration of hydrogen ions = [tex][H^+]=M_1[/tex]
[tex]pH=-\log[H^+][/tex]
[tex]5.0=\log[H^+][/tex]
[tex][H^+]=10^{-5} M[/tex]
Volume of the HCl solution = [tex]V_1=100 mL[/tex]
Concentration of hydrogen ions after dilution = [tex]M_2[/tex]
Volume of HCL solution after dilution = [tex]V_2=1 L=1000 mL[/tex]
[tex]M_1V_1=M_2V_2[/tex]
[tex]M_2=\frac{M_1V_1}{V_2}=\frac{10^{-5}M\times 100 mL}{1000 mL}[/tex]
[tex]M_2=10^{-6} M[/tex]
The Ph of teh new diluted solution ;
[tex]pH=\log[M_2][/tex]
[tex]=-\log[10^{-6}]=6[/tex]
6 is the pH of the diluted solution.
