You will collect data which will give you the information to calculate thepercentage of each component in the mixture and to calculate the percent of recovery for theexperiment.The flow chart below summarizes the different steps you will take to complete theexperiment. This schematic represents the series of operations involved.After drying and weighing the two components, you will calculate the percentage of eachcomponent in the mixture. You will then calculate the percent recovery of the components in themixture.Beaker #1Sio, (s) + NaCl (s)Add water andperform gravityfiltrationFiltrateNacI (aq)ResidueSiO, (s)Dry in Oven@ 125° CEvaporation to Drynesson a Hot PlateCool to room temperatureand obtain mass of dryfilter paper and sandCool to room temperatureand obtain mass of dryNaci(g part)(g whole)% by mass =х 100% recovery = (g SiO, + g NaCl) x 100(g original sample)% error =L(g SiO, +NaCl - g original sample) | x 100(g original sample)Fundamental Chemistry I39Arkansas Scholastic Press 12:06 1ullDone CHEM 1103 Lab Manual U...A student performed the experiment correctly and the initial massing correctly, but forgot to massthe crucible cover after heating. What errors would this cause in the calculation of the percent ofwater in the hydrate? Be specific.36Fundamental Chemistry IArkansas Scholastic PressLab 6. Separating the Components of a Binary MixtureLab 6 Pre-LabName:Date:Instructor:Time & Day of lecture:1. You will be separating a binary mixture in this experiment. What are the two compounds inthe binary mixture in this experiment?2. The separation will be quite simple because one of the compounds is soluble in water and oneis not. Which compound in the mixture is soluble and which is not?3. From your reading of the experiment and the flow chart, come up with reasonable definitionsor explanations of the terms residue and filtrate.4. A student was asked to determine the percentage of the components of a binary mixtureof KBr, potassium bromide, and Mg (OH),, magnesium hydroxide. The mass of the mixtureused was 6.321 grams. The student extracted the KBr with water since KBr is soluble in waterand Mg(OH), is not. The magnesium hydroxide remained in the container after the KBr wasextracted with water.After evaporation of the filtrate, the KBr residue was dried and weighed. Its dry mass wasfound to be 2.864g. The insoluble Mg(OH), was also dried and had a mass of 3.204 grams.a. Calculate the percent of KBr in the mixture.b. Calculate the percent of Mg(OH), in the mixture.c. Calculate the percent of recovery using the total mass of substances recovered.d. Calculate the percent error of this total recovery.Fundamental Chemistry I37Arkansas Scholastic Press
