A chemist needs to determine the concentration of a solution of nitric acid, HNO3. She puts 905 mL of the acid in a flask along with a few drops of indicator. She then slowly adds 0.600 M Ba(OH)2 to the flask until the solution turns pink, indicating the equivalence point of the titration. She notes that 245 mL of Ba(OH)2 was needed to reach the equivalence point.


What is the concentration of HNO3 if 0.294 mol are present in 905 mL of the solution?

Bob Cat is attempting to determine the molarity of an unknown solution of acetic acid. He began by mixing an aqueous NaOH solution and standardizing it by titration of KHP with phenolphthalein indicator. He then titrated the acetic acid solution with his standardized NaOH. The data from one of Bob’s trials is below, but he still needs to complete his calculations. The molar mass of KHP is 204.2 g. Titration of KHP Titration of Acetic Acid mass of KHP (g)...

The concentration of CO2 in air is determined by an indirect acid– base titration. A sample of air is bubbled through a solution containing an excess of Ba(OH)2, precipitating BaCO3. The excess Ba(OH)2 is back titrated with HCl. In a typical analysis a 3.5-L sample of air was bubbled through 50.00 mL of 0.0200 M Ba(OH)2. Back titrating with 0.0316 M HCl required 38.58 mL to reach the end point. Determine the ppm CO2 in the sample of air given...

A solution of NaOH (aq) of unknown concentration, is added from a buret into an Erlenmeyer flask containing 25.00 ml of 0.2000 M HCI (aq). A small amount of phenolphthalein indicator is also present in the acid, initally. A very pale pink but permanent color appears in the Erlenmeyer upon the addition of 41.22 ml of the base solution. The appearance of the color signifies the end point of the titration. a) Please write a balanced molecular equation for the...
