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.
The solubility product constants of PbSO4 and SrSO4 are6.3 x 10-7 and 3.2 x 10-7, respectively. What are the valuesof [SO42 -], [Pb2+], and [Sr2 + ] in a solution at equilibriumwith both substances?
During standardization, 0.7987 g of potassium hydrogen phthalate (KHP) used 38.29 mL ofNaOH, mL to reach the phenolphthalein end point. Calculate the molar concentration of thebase.
The solubility (denoted as s) of CaSO4 in pure water at 40o C is 1.09 grams per liter. What is the value of the solubility product of CaSO4?
For a titration to be effective, the reaction must be rapid and the yield of the reaction must essentially be 100%. Is Kc > 1, < 1, or ≈ 1 for a titration reaction? Kc is the product of all reaction products (choose from: Multiplied by, added to, divided by, subtracted from) the product of the reactants, with all concentrations of reactants and products raised to their respective stoichiometric powers. As the titration proceeds, the amount of reactants (choose from: Increases, decreases, remains the same) and the amount of products (choose from: Increases, decreases, remains the same). Because the value of the numerator is (Choose from much greater than, much less than, approximately equal to) the value of the denominator, the value of Kc will be (Choose from much greater than, much less than, approximately equal to)1 for an effective titration reaction.
A 1.00 liter solution contains 0.33 M acetic acid and 0.43 M sodium acetate. If 0.110 moles of calcium hydroxide are added to this system, indicate whether the following statements are true or false. (Assume that the volume does not change upon the addition of calcium hydroxide.) _______TrueFalseA. The number of moles of CH3COOH will decrease. _______TrueFalseB. The number of moles of CH3COO- will remain the same. _______TrueFalseC. The equilibrium concentration of H3O+ will remain the same. _______TrueFalseD. The pH will increase. _______TrueFalseE. The ratio of [CH3COOH] / [CH3COO-] will increase.
