Phenol (PhOH, MM = 94.11 g/mol) is a weak acid (pKa = 10.000). a) 0.515 grams of phenol is dissolved in enough water to make 125 mL of solution. What is the pH of this solution? Round your answer to the correct number of significant figure and enter it into the box below. If your answer is a decimal, include a 0 before the decimal point. Do not use scientific notation. pH = X 5.68 b) A sample of the phenol solution is titrated with 0.123 M KOH. How many mL of the KOH solution are required to titrate 15.00 mL of the phenol solution? Round your answer to the correct number of significant figures and enter it into the box below. If your answer is a decimal, include a O before the decimal point. Do not use scientific notation. volume of KOH= 5.34 mL c) What is the pH at the equivalence point? Round your answer to the correct number of significant figures and enter it into the box below. If your answer is a decimal, include a 0 before the decimal point. Do not use scientific notation. 11.3 pH=
