Question #55acc

Answer 1

`pH~~3.08`

Explanation:

Recall that the formula for `pH` is:

`color(blue)(|bar(ul(color(white)(a/a)pH=-log[H^+]color(white)(a/a)|)))`

where:
`pH=`pH
`[H^+]=`concentration of hydrogen ion

Determining the pH
To find the pH, substitute your known values into the `pH` formula and solve.

`pH=-log[H^+]`

`pH=-log(0.000841M)`

`color(green)(|bar(ul(color(white)(a/a)pH~~3.08color(white)(a/a)|)))`
