1S Refer 2. An "iodide/chloride/sulfate" unknown solution gave a white precipitate with aqueous AgNO3, and after centrifuging, the supernate gave a white precipitate with aqueous Ba(NO3)2. The original white precipitate dissolved completely in aqueous NH4OH, and produced a white precipitate after adding aqueous HNO3. State the anion(s) confirmed present and absent in the unknown solution. Anion(s) present Anion(s) absent

A solid containing tris was dissolved in water and brought to a total volume of 50.00 ml. A 10.00 ml aliquot of the solution was titrated with 0.09978 M HCl to a bromcresol green endpoint. The aliquot consumed 38.93 ml of titrant. Calculate the weight of tris in the original sample.
Hi! Please answer the two questions below given theri choices. Thank u!
The unknown solution contained… (multiple choice)
Provide full complete solution do not round off numbers and show proper labelling and cancellations
A solution containing a mixture of metal cations was treated with dilute HCl and no precipitate formed. Next, H, S was bubbled through the acidic solution. A precipitate formed and was filtered off. Then, the pH was raised to about 8 and H, S was again bubbled through the solution. A precipitate again formed and was filtered off. Finally, the solution was treated with a sodium carbonate solution, which resulted in no precipitation. Classify the metal ions based on whether they were definitely present, definitely absent, or whether it is possible they were present in the original mixture. Definitely present Definitely absent Possibly present Ag* Hg²+ Lit Ba²+ Pb2+ Mg²+ Hg3* 2+ Answer Bank Zn2+ Sn2+ Ni2+ Cu2+ Bi3+ A13+ Incorrect

Gravimetric Analysis. Please include complete solution, thank you. 4.) A 0.2025 g sample consisting of only BaCl2 and KCl required 20.25 mL of 0.1200 M AgNO3 solution for the quantitative precipitation of chloride. Calculate the %Ba and %K in the sample.
Finely ground mineral (0.9315 g) was dissolved in 25 mL of boiling 4 M HCl and diluted with 175 mL H2O containing two drops of methyl red indicator. The solution was heated to 100C, and 50 mL of warm solution containing 2.0 g (NH4)2C2O4 were slowly added to precipitate CaC2O4. Then 6 M NH3 was added until the indicator changed from red to yellow, showing that the liquid was neutral or slightly basic. After slow cooling for 1 h, the liquid was decanted and the solid transferred to a filter crucible and washed with cold 0.1 wt% (NH4)2C2O4 solution five times until no Cl- was detected in the filtrate upon addition of AgNO3 solution. The crucible was dried at 105C for 1 h and then at 500 ± 25 C in a furnace for 2 h. Ca2+ + C2O42- --> CaC2O4.H2O(s) -->500C CaCO3(s) The mass of the empty crucible was 16.9743 g, and the mass of the crucible with CaCO3(s) was 17.198164 g. Find the wt% Ca in the mineral. a) Why is the unknown solution heated to boiling and the precipitant solution,…
