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.
Analysis of dissolved sulfate concentration is based on the precipitation reaction of barium sulfate, creating Baso4 5) (named barite) and its settling. The following water quality is given: TDS = 650 mg/I, (SO) = 40 mg/l as S. Solubility constant of BaSO:: Kip (Baso.) = 1.1 1010 Determine how many mg of BaCl, should be added to 200 ml of a solution at the given quality for completely precipitating the sulfate. That is, calculate the dose required for 99.9% removal, while assuming saturation with respect to barite is immediately reached.
