What is the normality? How many mL of 1N H2SO4 will be required to neutralize this solution? From this volume of acid, compute the percent purity of NaHCO3.Calculate the volume in liters of 0.545 M KOH necessary to titrate 0.0113 moles of hydrochloric acid, HCl, to a phenolphthalein end-point. Report the answer with three significant figures.
- A solution contains a mixture of Na2CO3 and NaOH. Using phenolphthalein indicator 25 mL of mixture required 19.5 mL of 0.995 M HCl for the endpoint.
