If [ H ₃ O ^+] of a solution is 1 10⁻⁴ . What is the value of pOH at 298 , K ?

Step-by-step solution

Given [ H ₃ O ^+] = 1 10⁻⁴ M. The pH of the solution is given by: pH = - [ H ₃ O ^+] pH = - (1 10⁻⁴) = 4 At 298 , K , the relationship between pH and pOH is: pH + pOH = 14 Substituting the value of pH: 4 + pOH = 14 pOH = 10 Answer: 10
