Find out the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. You have a 0.1351M standard solution. You take a 25.00mL sample of the original acid solution as well as dilute it to 250.0mL. You then take a 10.00mL sample of the dilute acid solution as well as titrate it with the standard solution. Need 19.95mL of the standard solution to reach the endpoint. Explain what is the concentration of the original acid solution in M?
Predict how the inert pair effect would manifest itself beyond group 15 and compare your predictions with the chemical properties of the elements involved.
