Solving the problems
You need to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. You have a 0.1379 M standard solution. You take a 25.00 mL sample of the original acid solution and dilute it to 250.0 mL. You then take a 10.00 mL sample of the dilute acid solution and titrate it with the standard solution. You need 13.88 mL of the standard solution to reach the endpoint. What is the concentration of the original acid solution? A 60.00 mL solution of 0.4500 M AgN03. was added to a solution of AsO,*3-. Ag3AsC>4 precipitated and was filtered off. Fe3f was added and the solution was titrated with 0.2400 M KSCN. After 36.90 mL of KSCN solution had been added, the solution turned red. What mass of AsO^ was in the original solution? Show transcribed image text
