Achemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. he has a 0.1678 m standard sodium hydroxide solution. he takes a 25.00 ml sample of the original acid solution and dilutes it to 250.0 ml. then, he takes a 10.00 ml sample of the dilute acid solution and titrating it with the standard solution. the endpoint was reached after the addition of 19.88 ml of the standard solution. what is the concentration of the original sulfuric acid solution?
Answers: 1
in 10 mL of diluted solution = 1/2 x moles of NaOH
x 0.00333 = 0.00166 mol
x 0.00166 = 0.0415 mol
