Question

If a sample of a certain solution is determined to have a [H3O+] concentration of 9.49×10−1 moles/liter, what is its pH? Round off your answer to one decimal place.

Answer 1

Answer: The pH of the solution is 1.022

Explanation:

pH is defined as the negative logarithm of hydrogen ion concentration present in a solution.

To calculate the pH of the reaction, we use the equation:

$pH=-\log[H^+]$

where,

$[H^+]=9.49\times 10^{-1}mol/L$

Putting values in above equation, we get:

$pH=-\log(9.49\times 10^{-1})\\\\pH=1.022$

Hence, the pH of the solution is 1.022
