I get #1.12#.

Explanation:

We use the #"pH"# equation, which states that,

#"pH"=-log[H^+]#

  • #[H^+]# is the hydrogen ion concentration in terms of molarity #("M")# or #"mol/L"#.

So here, we have,

#[H^+]=0.075 \ "M"#, since the substance we are dealing with is an acid.

And so, the #"pH"# will be,

#"pH"=-log[0.075]#

#~~1.12#
