ANSWER ONLY QUESTION 4, QUESTION 3 is for reference only
QUESTION 3 Determining the amount of sulfate ion (SO.2-) dissolved in seawater in the unit of molarity As we all know seawater is salty. This is because many salt ions are dissolved in the seawater, which is not the case in the freshwater. Among many ions, Nat and Clare the most abundant ions dissolved in the seawater followed by SO,, Mg²+, Ca?', and Kions. So sulfate (S0?) ion is the...

An unknown metal sulfate is found to be 55.66% SO42 by mass. Assuming that the charge on the metal cation is +3, determine the identity of the cation 1. 2. The unknown metal sulfates are hygroscopic and will absorb water from air. They must thus be kept in desiccators to remove any absorbed water and keep them dry. How would your results be affected if your unknown sample was not desiccated? Would you obtain a hig her or lower mass...

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...

EXPERIMENTAL PROCEDURE 1. Using a 50.0 mL graduated cylinder, obtain 40.0 mL of the unknown water sample. This ample contains an unknown amount of BaCh, Pour this into a 100 mL beaker 2. Add 20.0 ml. of the NasPO solution provided to your unknown solution in the 100 ml, beaker The amount of NaPOs you are adding in the 20.0 ml, of solution is more than enough to provide for complete reaction of the unknown BaClh, Consequently, you can be...

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+...
