Potassium hydrogen phthalate is commonly used as a standard in acid-base titrations. Consider the following situation: 3 drops of phenolphthalein are added to a 25mL sample of unknown KHP concentration. The solution is then titrated with 0.012M Ca(OH)2. After 39.6mL of base is added the acid solution turns pink. Calculate the experimental value for Ksp for KHP and determine whether it is within 10% of the theoretical Ksp value (solubility = 8.0g/L). If not, give one reason why this error might have occurred.
