Thesolutionto determine the pH in a 0.667 M NaOH solution is to use the formula for calculating pH, which involves calculating the pOH first and then solving for pH using the equation pH + pOH = 14. The pH in this case is 13.82.To determine the pH in a 0.667 MNaOHsolution, you need to use the formula for calculating pH. First, calculate the pOH using the equation: pOH = -log[OH-]. In this case, [OH-] is 0.667 M, so pOH = -log(0.667) = 0.18.Next, use the equation pH + pOH = 14 tocalculatethe pH. Rearrange the equation to solve for pH: pH = 14 - pOH.Substituting the pOH value of 0.18, we get pH = 14 - 0.18 = 13.82. Therefore, the pH of a 0.667 M NaOH solution is 13.82.In conclusion, the solution to determine thepHin a 0.667 M NaOH solution is to use the formula for calculating pH, which involves calculating thepOHfirst and then solving for pH using the equation pH + pOH = 14. The pH in this case is 13.82.To know more aboutsolutionclick here:brainly.com/question/30665317#SPJ11...
