Answer:
The answer is
0.38
Explanation:
HCL is a strong acid and therefore undergo complete dissociation
We have
[tex] HCL \rarr H^{ + } \: + \: Cl^{ - } [/tex]
The concentration of Hydrogen ion is also 0.415 M
The pH of a solution can be found by using the formula
[tex]pH = - log( {H }^{ + } ) [/tex]
So we have
[tex]pH = - log(0.415) \\ = 0.381951903...[/tex]
We have the final answer as
0.38
Hope this helps you
