QUESTION 19 10 p. A student is trying to determine the concentration of an acetic acid (HC2H302) solution. They place 5.00 mL of it in a flask and titrate it with a 0.100 M NaOH solution. At the endpoint of the titration, they find that they have used 23.14 ml of the NaOH solution. Based on this information answer the following questions. a) How many moles of NaOH are used to reach the endpoint? moles NaOH b) How many moles...

1. A student carries out a back titration to determine the concentration of ammonium chloride in a solution. The student collects 10.80 mL of the original NH4Cl solution and dilutes it to 250.0 mL (we will refer to this as the dilute NH4Cl solution). Then 25.00 mL of the dilute NH4Cl solution are transferred to an Erlenmeyer flask and 25.00 mL of 0.1963 M NaOH are added. Calculate the moles of NaOH added to this Erlenmeyer flask. 2. In the...
