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 formul the precipitate. If it cannot, type "No" Y or N Reagent Formula of Precipitate if YES 1. K,CO, 2. NaCl 3. Na,SO,

What happens when potassium iodide is added to a solution of lead nitrate? Potassium nitrate precipitates out. Lead iodide precipitates out. Gaseous lead iodide forms. Nothing - there is no reaction between potassium iodide and lead nitrate.

When 50.0mL of a 0.335M potassium carbonate solution is mixed with 0.045L of a 0.390M nickel(II) chloride solution the following reaction occurs: K2CO3 (aq) + NiCl2 (aq) → a. Complete the reaction equation b. Calculate the mass of precipitate formed c. Calculate the concentration of each ion in the mixture when the reaction is complete

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

A solution contains Cr3+ and Mg2+. The addition of 1.00 L of 1.51 M NaF solution is required to cause the complete precipitation of these ions as CrF3(s) and MgF2(s). The total mass of the precipitate is 50.1 g . Find the mass of Cr3+ in the original solution.

If the following ions are placed in a test tube, the precipitate formed is (Information in photo)

Predicting precipitation Complete the table below by deciding whether a precipitate forms when aqueous solutions A and B are mixed. If a precipitate will form, enter its empirical formula in the last column. Does a empirical formula of precipitate form solution A solution B when A and B precipitate are mixed? ? manganese(II) chloride zinc sulfate yes no ammonium bromide sodium acetate yes no iron(II) sulfate sodium sulfide yes no

12. In a titration of HNO3, you add a few drops of phenolphthalein indicator to 50.00 L if acid in a flask. You quickly add 20.00 mL of 0.0502 M NaOH but overshoot the endpoint, turning the solution a deep pink color. Instead of starting over you add an additional 30.00 mL of the acid, turning the solution colorless. It then takes 3.22 mL of the NaOH to reach the endpoint. a. Write the Molecular, Total Ionic, and Net Ionic Equations for this reaction. b. What is the concentration of the HNO3 solution? c. How many moles of NaOH were in excess after the first addition?
