A student was asked to determine the percentage of each component in a mixture of sodium nitrate (NaNO3) and calcium carbonate (CaCO3). The mass of the sample used was 2.96 g. The student extracted NaNO3 from the mixture with water and separated the insoluble CaCO3 from the solution by filtration. After evaporating the filtrate, the student recovered and dried the NaNO3, and found that it weighted 0.49 g. The student dried the insoluble residue of CaCO3 and found that it weighted 2.42g.

Calculate the percent NaNO3 in the mixture.

Answer #1

Given:

given weight of the sample used =2.96 g

Dried NaNO3 weight =0.49

Insoluble residue of CaCO3 weight= 2.42 g

Solution:

Mass of NaNO3 Percentage of NaNO, in a mixture= -X100 Mass of mixture 0.49 -x100 2.96 =16.5%

    Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
