The concentration of CO2 in air may be determined by an indirect acid-base titration. A sample of air is bubbled through a solution containing an excess of barium hydroxide, and the CO2 is removed by precipitation as it reacts with Ba(OH)2. 8. Ba(OH)2(aq) + CO2(g) → BaCO3(s)+H2O(1) Not all of the Ba(OH)2 reacts with CO2-some is left over. The mixture is filtered to remove solid BaCO3, the solid is rinsed, the filtrate and rinsings are combined, and the leftover Ba(OH)2 is titrated with HCl. Ва(ОН)2(аq) + 2 HС(ад) —> ВаСlz(ад) + 2 H-0() In a typical analysis, a 5.0-L sample of air was bubbled through 50.00 mL of 0.0320 M Ba(OH)2. Back titrating (that was a hint) with 0.0256 M HCl required 38.08 mL to reach the end point. Determine the concentration of CO2 (FM = 44.01) in the sample of air in units of mg/L.

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. [] --> Ba(ClO3)2 (aq) + H2O (l)
Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHC8H4O4.

You have an aqueous solution containing one or more of the following anions CO3*, cr, r and SO4. When you add Ba(NO)3(aq) you get a precipitate. You separate the precipitate (A) from the supernatant (B). To the precipitate (A), you add HCI(aq) and the solution fizzes and produces a colorless, odorless gas. To the supernatant (B), you add Ag(NO)3 and there is no reaction. Identify which ions are present, might be present, or are not present Co32- A. present B. not present CI C. might be present Soą2-
A chemistry student needs to standardize a fresh solution of sodium hydroxide. She carefully weighs out 316.mg of oxalic acid H2C2O4 , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in 250.mL of distilled water. The student then titrates the oxalic acid solution with her sodium hydroxide solution. When the titration reaches the equivalence point, the student finds she has used 93.2mL of sodium hydroxide solution. Calculate the molarity of the student's sodium hydroxide solution. Be sure your answer has the correct number of significant digits.

6 a b U d [Tutorial: Titration stoichiometry] This question will walk you through the steps of calculating the volume of titrant required to reach the endpoint based on the volume and concentration of analyte. Consider the standardization of NaOH by titration with C,H,O, according to the following chemical reaction: 3 NaOH(aq) + C,H,O,(aq) = Na,C,H,O,(aq) + 3 H₂O(l) Step 1: Evaluate the question. How many moles of aqueous sodium hydroxide (NaOH) will react to completely neutralize one mole of aqueous citric acid (C,H,O,)? Which equation will be most helpful for solving this problem? Calculate the volume in mL of a 0.200 M NaOH solution needed to neutralize 345 mL of 0.033 MC,H,O, standard solution. Based on the fact that NaOH is a strong base and C,H,O, is a weak acid, how would you describe the pH of the solution at the endpoint, where moles of base = 3 times the moles of acid?
