A solution at 25 ∘C has pOH = 10.53. Which of the following statements is or are true? The solution is acidic. The pH of the sol
Lady bird [3.3K]

Answer:

The true statements are:

The solution is acidic

The pH of the solution is 14.00 - 10.53.

10^{-10.53}=[OH^-]

Explanation:

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

pH=-\log[H^+]

  • The pH value more 7 means that hydrogen ion concentration is less ,alkaline will be the solution.
  • The pH value less 7 means that hydrogen ion concentration is more ,acidic will be the solution.
  • The pH value equal to 7 indicates that the solution is neutral.

The pOH of the solution is defined as negative logarithm of hydroxide ion concentration present in the solution .

pOH=-\log[OH^-]

The pOH of the solution = 10.53

10.53=-\log[OH^-]

10^{-10.53}=[OH^-]

The pH of the solution = ?

pH+pOH=14

pH=14-pOH=14-10.53=3.47

Here, the pH of the solution is less than 7 which means that solution acidic.
