Question

What is the formula for calculating pH?

• A. $pH=-log\left[H_3{O}^{+}\right]$
• B. $pH/log=-log\left[H_3{O}^{+}\right]$
• C. $pH=-log\left[O{H}^{-}\right]$
• D. $pH=-log/\left[H_3{O}^{+}\right]$
• E. $pH=log\left[H_3{O}^{-}\right]$

Answer 1

The correct option is A $pH=-log\left[H_3{O}^{+}\right]$

The formula for calculating pH is $pH=-log\left[H_3{O}^{+}\right]$
pH is the negative logarithm (to base 10) of hydronium ion concentration.
