**Orthocresol (C₇H₈O) pH Determination Problem**Orthocresol (C₇H₈O) has a \( K_a = 5.50 \times 10^{-11} \). If 100.0 mL of a 0.5000 M aqueous orthocresol solution is mixed with 100.0 mL of a 0.5000 M aqueous sodium hydroxide solution, the resulting solution will have a pH:- A. =7- B. <7- C. >7- D. Cannot be predicted from the information given**Explanation:**This problem involves the mixing of a weak acid (orthocresol) with a strong base (sodium hydroxide). The \( K_a \) value provided indicates the acid's dissociation in water.**Potential Analysis:**- **Neutralization**: 100.0 mL of 0.5000 M orthocresol and 100.0 mL of 0.5000 M NaOH have equal molar amounts, likely leading to complete neutralization.- **Resulting pH**: After neutralization, the resulting solution typically has a pH determined by the presence of the conjugate base of orthocresol and any leftover hydroxide ions, which usually makes the solution basic (pH > 7).Given these conditions, analyze the information and apply your understanding of acid-base reactions to determine the correct answer.
