Question

A solution is tested with litmus paper and its pH value is 3. 34. What color does litmus paper turn in this solution? 35. What is the hydronium ion concentroation of this solution? 36. What is the hydroxide ion concentration of this solution? 37. What is the pOH value of this solution is 3​

Answer 1

The pOH value can be calculated by taking the negative log of the hydroxide ion concentration, which gives -log(2.12 x 10^-11) = 10.67. Since pH + pOH = 14, we can calculate the pH value as 14 - 10.67 = 3.33, which matches the initial pH value of the solution in question.
