If the barium sulfate precipitate is not dried thoroughly, will the experimentally determined concentration be higher or lower than the true value? Concisely explain based on how the molarity is calculated.

The addition of hydrochloric acid to the solution of containing the silver group of cations is to selectively precipitate out the lead(II) ions. O True O False

A solution contains 8.85×103 M potassium fluoride and 1.45x102 M ammonium carbonate. Solid lead nitrate is added slowly to this mixture. What is the concentration of carbonate ion when fluoride ion begins to precipitate? [carbonate] = M

A student is given the following labeled solutions: NaCl, AgNO3, FeCl2, HCI, and KaCo The data was collected and summarized in the following table. The student then receives 5 test tubes labeled A, B, C, D, and E, which contain the five solution above. Data collect after mixing these solutions are given in the second table below. 4.
