A titration is carried out to determine the concentration of the acid in an old bottle of aqueous HClHCl whose label has become unreadable. What is the HCl concentration if 75.3 mL of 0.250 M NaOH is required to titrate a 10.0 mL sample of the acid?

3. Consider the titration Ba(OH)2 (aq) + 2 HNO3 (aq)→ Ba(NO3)2 (aq) + 2 H2O (1).The equivalence point is reached when 18.91 mL of 0.200 M HNO3 is titrated into 25.00 mL of the Ba(OH)2 solution. Calculate the molarity of the Ba(OH)2 solution. Be sure to account for the stoichiometry of the reaction. 4. In a titration of KOH solution, 0.0742 g of KHP is weighed into a flask and dissolved in deionized water. The equivalence point of the titration is reached when 7.05 mL of KOH solution is added to the KHP solution. a) How many moles of KHP are in the solution? b) How many moles of KOH will have to be titrated to neutralize the KHP? c) What is the molarity of the KOH solution?

A student needs to dilute a 0.25 M Pb(NO3)2 solution to make 63.0 mL of 0.19 M Pb(NO3)2. Set up the calculation by placing the values with the correct units into the equation. Then, calculate the volume, in milliliters, of the 0.25 M Pb(NO3)2 solution that is needed. X Answer Bank 0.19 M 0.19 mL 63.0 L 0.25 M 63.0 mL 0.25 mL mL

15. A NAOH(aq) solution and an acid-base indicator are used to determine the molarity of an HCI(ag) olution. A 25.0-milliliter sample of the HCI(aq) is exactly neutralized by 15.0 milliliters of 0.20M laOH(aq). Identify the laboratory process described in this passage.

A 1.22 g sample of KHP is used to titrate a NaOH solution.  A student finds that it requires 15.00 mL of the NaOH solution to reach the end point.  What is the molarity of the NaOH solution?

4. A student did not read the directions to the experiment properly and mixed up where to put the NaOH and the HCl solutions. He put the HCl in the buret and the NaOH in the flask. He then added a drop of the phenolphthalein to the solution in the flask. Does the student need to empty out all of the solutions and start over again or can he go ahead and run the titration?

Write a balanced equation for the precipitation titration of the "iron chloride" and sodium hydroxide. Include physical states. balanced equation:

You are preparing standard acid and base solutions for the laboratory, using potassium hydrogen phthalate (KHC₈H₄O₄, abbreviated KHP) as the primary standard. KHP (molar mass = 204.22 g/mol) has one acidic hydrogen. You prepared solutions of both NaOH and HCl. It took 22.65 mL of the NaOH solution to titrate (react exactly with) 1.55 g KHP. It then took 32.35 mL of HCl solution to titrate 25.00 mL of the NaOH solution. What is the molarity of the HCl solution?
