A student forgets to weigh a mixture of sodium bromide dihydrate and magnesium bromide hexahydrate. Upon strong heating, the sample loses 233.374 mg of water. The mixture of anhydrous salts reacts with excess AgNO3 solution to form 5.65x10-3 mol of solid AgBr. Find the mass % of sodium bromide dihydrate in the mixture.

A 18.88-g sample consisting of a mixture of sodium chloride and potassium sulfate is dissolved in water. This aqueous mixture then reacts with excess aqueous lead(II) nitrate to form 36.80 g of solid. Determine the mass percent of sodium chloride in the original mixture.
enbel ZFIO You want to analyze a magnesium nitrate solution. (a) In your lab you have salts of aluminum acetate, barium bromide, and sodium hydroxide. Which salt would you use to form a precipitate with the magnesium ions? ANSWER: (b) What mass of the salt you choose from part (a) is needed to precipitate the Mg2+ ions from 38.0 mL of 0.750 M magnesium nitrate solution? ANSWER: FULL HD Upon applied external force, sodium aride (NaN) rapidly decomposes into sodium...

Experiment 7: Grignard Reaction. Introduction Discovered by French chemist Victor Grignard, the reaction that now bears his name is an example of the preparation of an organometallic reagent. In this lab, phenylmagnesium bromide is the Grignard of interest, and it will be added to an aldehyde to produce an alcohol. Lab Objectives 1. To study organometallic reagents in general. benzophenone. 2. To prepare phenylmagnesium...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
Purpose: To calculate the amount of AgNO3 present in an unknown solution of water through the process of gravimetric analysis with NaCl. Background: Have you ever had difficulty lathering soap or find that the scum in your shower constantly needs to be removed? These are signs of “hard water.” Soap does not lather well in hard water because metal ions, such as Ca2+, form precipitates, creating “soap scum.” A precipitate is an insoluble compound that forms when soluble ions in...
