Question
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. Ag+...

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 (Br). To this solution...

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...
