A. What is the pH of an aqueous solution with a hydrogen ion concentration of [H*] = 8.1 x 10-5 M? pH B. What is the hydroxide ion concentration, [OH], in an aqueous solution with a hydrogen ion concentration of [H*] = 8.1 x 10-5 M? [OH-] = C. A monoprotic weak acid, HA, dissociates in water according to the reaction HA(aq) = H*(aq) + A-(aq) The equilibrium concentrations of the reactants and products are [HA] = 0.190 M, [H*] = 4.00 x 104 M, and [A-] = 4.00 x 104 M. Calculate the Ką value for the acid HA. Ka = TOOLS x10"
2. A student prepares a solution of H3PO4 and wishes to determine its precise concentration. A 25.0 mL sample of the H3PO4 is titrated with a standardized 0.073 M NaOH solution. The titration requires 36.4 mL of the NaOH solution to reach the equivalence point. A) Write the balanced equation between H₂PO4 and NaOH. H3PO4 (aa)+ NaOH B) How many moles of NaOH were needed to reach the equivalence point? C) What is the molarity of the H3PO4 solution?
Potassium is a very reactive metal, but in compounds it is present as the potassium ion and is not very reactive. For example, dry potassium bicarbonate powder can be used to extinguish burning liquids. Why is there such a difference in the reactivity of potassium metal and the potassium ion? A. The potassium in the bicarbonate salt is a base, but the potassium metal is an acid. B. The potassium in the bicarbonate salt is an acid, but the potassium metal is a base. C. The combustion of the liquids suppresses the potassium's ability to react. D. The potassium metal can readily ionize by losing its one valence electron; the potassium in the bicarbonate salt is already ionized. E. The potassium atom is bonded to an oxygen atom in the bicarbonate salt, but in the metal it is unbound and free to react.
