When separating Sand from Salt in a mixture during an experiment, why would you need to add water to the salt twice when seperating the salt?
1.describe how you would separate a mixture of acetanilide and sand 2.water is a convenient solvent for recrsytallizing what type of compound. 3. why is fluted filter paper usually used when doing the hot filtration during a recrystallization. 4.describe how seed crystal are used in recrystallization. 5.explain the adage " like dissolve lik
4. a. A sample of a CaCI 2HO/K C,0, HO solid salt mixture is dissolved in -150 mL of deionized water previously adjusted to a pH that is basic. The precipitate, after having been filtered, was air-dried and weighed. Data for Trial I were obtained as shown. Complete the following table. (See Report Sheet.) Record calculated values with the cor- rect number of significant figures. A. Precipitation of CaC,0,H from the Calculation Zone Salt Mixture 3. Mass of salt mixture...
Solute settles down for which of the following mixture. Salt and water Homogenous mixture True Solution O Colloid O Suspension
could this experiment have been done in a different order? for example, fe filing being removed at the end of the scheme. Why or Why not? Here is the procedure: INTRODUCTION Most of the matter around us con combination of two or more Mixtures have the following fundamental proper natter around us consists of mixtures of different substances. A mixture results from the tivo or more pure substances, elements or compounds that do not react chemically. • Each component of...
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...
Solute settles down for which of the following mixture. Salt and water Homogenous mixture True Solution Colloid Suspension
Which of the following techniques will not be used in the Ferrofluid experiment? --------- decanting pipetting vacuum filtration centrifuging Which of the follow is not true about ferrofluids? --------- Ferrofluid has the fluid properties of water and the magnetic properties of magnetite. The particle size of the magnetite is in the microscale range The magnetite in the ferrofluid will permanently stain clothing. The properties of the ferrofluid are extremely sensitive to the care and precision with which the procedure is...
