- What is the practical application of gravimetric method of analysis.2. Formaldehyde. Qualitative and quantitative analysis.You want to determine the concentration of NaCl in a water. In preliminary analysis, it appears to be saline water with a NaCl content of approximately 4%. Should you dilute the sample if your titrant has a concentration of 0.1 M and you want to spend 25 mL of sample? Solution: You must dilute approximately ten times, taking 10 mL of sample and making up to 100 mL. In this way, 17.20 mL of titrant will be spent.
- A sample of hydrochloric acid is standardized using sodium bicarbonate, NaHCO3. A.) Write the balanced chemical equation for the reaction of hydrochloric acid with sodium bicarbonate. B.) Calculate the molar concentration of the hydrochloric acid if 35.18 mL of hydrochloric acid was required to neutralize 0.450 g of sodium bicarbonate to a phenolphthalein end point. C.) Calculate the mass percent concentration of hydrochloric acid using the molar concentration calculated in part b and assuming the density of the solution is 1.01 g/mL.How would you turn a qualitative experiment into a quantitative experiment?On their second titration trial, the CHM 111 student recorded an Initial titrant volume of 9.95 mL and a Final titrant volume of 29.80 mL.
