Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the formula KHC8H4O4. This is often written in the short-hand notation as KHP. If 25.0mL of a potassium hydroxide solution are needed to neutralize 2.26g of KHP, what is the molarity of the potassium hydroxide solution? Potassium hydrogen phthalate sometimes called potassium biphthalate, as shown on this bottle is an acid that is convenient to store and use because it is a solid.
If 20 mL of a hydrochloric acid solution (HCl) required 18 mL of a sodium hydroxide in a titration and 35mL of the said base is equivalent to 0.8323 g of potassium bipthalate (KHC8H4O4), what would be the normality of the sodium hydroxide solution used in the titration?

42.5 mL of 1.3M KOH are required to neutralize 50.0 mL of H2SO4. This sulfuric acid is further used to standardize NaOH solution. 20mL aliquot of the NaOH solution is obtained and 2 drops of phenolphthalein is added. The initial reading on the buret is 13.2 mL. After the titration, the exact normality of the NaOH solution is found to be 1.254N. (a) What is the molarity of H2SO4? (b) How much of the sulfuric acid is used? (c) What is the final reading on the buret?

A shipment of containing NaOH (40 g/mol) and Na2CO3 (106 g/mol) was declared to contain less than 10 % impurity. However, Noel is suspicious that the declared impurity is higher. Being the best and brightest employee of the year, Noel weighed 1.000 g sample, dissolved in 50.0 mL of distilled water and titrated with cold 0.5000 M HCl. With Phenolphthalein as indicator, the solution turns colorless after the addition of 30.00 mL of the acid. Methyl Orange is then added, and 5.00 mL more of the acid is required before this this indicator changes color. Calculate the following: a. Determine the volume of the acid to fully neutralize NaOH (final answer up to one decimal place) =
20 ml of a 100 mg/l phenol solution in water is placed in a vial with 20 ml of a fluorocarbon solvent. The organic phase (fluorocarbon solvent) is immiscible with water. The vial is completely filled with the two phases, thus there is no air or contaminant volatilization. After an hour of agitation, the two phase system reaches equilibrium. The two phases are separated and the fluorocarbon is analyzed for total phenol. The resulting phenol concentration in the organic phase is 16.0 mg/l. Compute the unitless partition coefficient (KF-W) for phenol. Compare your calculation with KF-W obtained from an empirical relationship: log10KF-W 0.71 - 0.862log10 CWsat. KF-W means the partition between the fluorocarbon solvent, F, and water, W. Only typed solution.
