Determining the amount of sulfate ion (SO2) dissolved in seawater in the unit of molarity QUESTION Sulfate concentration in the seawater is about 28 mm (0.028 M). Take the reverse approach to the calculation procedure in the previous Question #1 (so called a backward calculation) and find a rough estimate for the volume of the seawater sample you may need to take from the beach like the one below. A 20.0 mL sample solution contains unknown amount of bromide ion...

QUESTION 1 A 20.0 mL sample solution contains unknown amount of bromide ion (Br). To this solution was added the solution that contains plenty of AgNO3. AgBr precipitates were formed. The precipitate were filtered and measured to be is 0.6964 g. What is the molarity of bromide ion in the original sample solution? The molar mass of Br = 80.0 g; the molar mass of AgBr = 188 g. (Solution) AgNO, is soluble and thus exists Ag+ ion and NO3-ion....

1- The concentration of bromide ion may be determined by gravimetric analysis, using this reaction: Ag * (aq) Br (aq) AgBr (s) A 0.500-L aqueous solution containing bromide was reacted with excess Ag. If the AgBr precipitate formed in this reaction has a mass of 0.0035 g, how many moles of Br were in the solution? What was the molarity of Br in the solution? 2-Identify each of these reactions as precipitation, neutraliza tion, or metal displacement: a. Ba (OH),...

A student prepared 7.2 g of Co,(NH3),Cl . She then analyzed the compound to find the values of x, y, and z. In the gravimetric determination of chloride, she weighed out a 0.2988 g sample of the product compound and reacted it with AgNO3. The following data were obtained: Mass of crucible plus AgCl 19.0020 g Mass of crucible 18.4628 g a. Calculate the mass of...
