Answer:
The concentration of hydronium ions in solution is [tex]2.75\times 10^{-3} M[/tex].
Explanation:
The pH of the solution is defined as negative logarithm of hydronium ions concentration in a solution. Mathematically written as:
[tex]pH=-\log[H_3O^+][/tex]
Given, the pH of the solution = 2.56
[tex]2.56=-\log[H_3O^+][/tex]
[tex][H_3O^+]=0.002754 M=2.75\times 10^{-3} M[/tex]
The concentration of hydronium ions in solution is [tex]2.75\times 10^{-3} M[/tex].
