what chemical could you add to effectively separate Ag from Al if both ions are present in a solution of soluble silver and aluminum salts? what procedure would you use to separate them?

now you return to the test tube containing Group III ions. After testing, you have a pink precipitate. Explain the identity of the Group III ions and how you came to this conclusion

[References) Use the References to access important values if needed for this question. In the laboratory you are given the task of separating Ag* and Fe2+ ions in aqueous solution. For each reagent listed below indicate if it can be used to separate the ions. Type "Y" for yes or "N" for no. If the reagent CAN be used to separate the ions, give the formula the precipitate. If it cannot, type "No" Y or N Reagent Formula of Precipitate if YES 1. K,CO, 2. NaCl 3.

All the chloride in a 5.00 g sample of an unknown metal chloride is precipitated as AgCl with 70.9 mL of 0.2010 M AgNO3. What is the percentage of chloride in the sample?

6. The following reaction forms a white precipitate. Is this a redox reaction? AgNO3(aq) + HCl(aq) → HNO3(aq) + AgCl(s)

Tungsten trioxide (WO,) has a rich yellow color and is often used as a pigment in ceramics and paints. To test a ceramic vase for its WO, content, a 10.15 g sample of the vase was ground and reduced with Pb(Hg) to convert any WO, to W³+. The resulting W3+ was transferred to 500.0 mL of 1.00 M HCI. A 100.00 mL aliquot of the HCl solution required 14.78 mL of 0.08271 M potassium permanganate (KMNO,) to reach the purple endpoint. A blank required 0.26 mL. Balance the redox reaction. redox reaction: MnO, + W3+ Mn2+ + WO3+ Determine the percent WO, in the ceramic sample. percent WO3: %

answer 4, 5

When excess lead(II) nitrate was added to 225 mL of a solution of potassium iodide, a solid precipitate formed. The dry precipitate had a mass of 7.25 g. What was the concentration of iodide ions in the solution of potassium iodide? a)  0.193 mol/L   b)  0.140 mol/L   c)  0.280 mol/L   d)  0.070 mol/L   e)  0.096 mol/L

Does a reaction occur when aqueous solutions of sodium carbonate and manganese(II) iodide are combined? O yes no If a reaction does occur, write the net ionic equation. (Use the solubility rules provided in the OWL Preparation Page to determine the solubility of compounds. Be sure to specify states such as (aq) or (s). If a box is not needed leave it blank.) + →

11. What volume of a 0.2087 M solution of permanganate ion (under basic conditions) will react with 27.00 mL of .0990 M sulfite ion solution. Manganese(II) oxide solid and sulfate ions are the products. If0 2500 g sample of an unknown triprotic acid is neutralized by 14.2 mL of 0.187 M stron
