Diluted  sulfuric acid solution that is .500m.

the original stock is 18.0m  and pull out 2.50 ml 

would silver react with diluted sulfuric acid? why or why not? would magnesium react with diluted sulfuric acid? why or why not?

A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1294 M0.1294 M standard sodium hydroxide solution. He takes a 25.00 mL25.00 mL sample of the original acid solution and dilutes it to 250.0 mL.250.0 mL. Then, he takes a 10.00 mL10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 17.43 mL17.43 mL of the standard solution. What is the concentration of the original sulfuric acid solution?
