You need to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. you have a 0.1292 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 14.24 ml of the standard solution to reach the endpoint. what is the concentration of the original acid solution?
