HELP DETERMINING POSSIBLE SALTS FROM DATA CONCLUSION. Possible salts: Ammonium nitrate, ammonium sulfate, sodium nitrate, potassium sulfide and barium nitrate. Data: The sample completely dissolves in water and is divided into 3 parts. 1. Adding silver nitrate solution results in a black precipitate that is insoluble in NH3. 2. Heating the sample after adding sodium hydroxide produces a gas with the odor of ammonia and which turns litmus paper blue. 3. Adding sodium sulfate solution results in a white precipitate....

You need to measure pH of a solution known to be made from a metal hydroxide, but you don't have a meter or any indicators. You do happen to have some lead (II) nitrate that is soluble, and you remember that lead (II) hydroxide is insoluble. You add some to 1 liter of your unknown solution and a precipitate forms. You add more until the precipitate stops forming and then a bit more just in case. After you filter and...

A chemist prepares five beakers with exactly 1.0 M of the specified salt dissolved in water. The solutions are combined in a series for four steps. In each reaction assume complete formation of any solid products (ignore equilibrium). Be careful as some reactions may only require half the available ion. 22. Step 1: The barium chloride solution is poured into the lead(II) nitrate solution. What (if any) precipitate forms? 23. Step 2: Sodium hydroxide solution is poured into the aqueous...

An evil maniac has dumped one metric ton (1,000 kg) of lead nitrate into a Bayou feeding into the City of Houston water supply. Assume the bayou contains roughly 106 L of water and it is naturally buffered to a pH of 7.000 (pH does not change). a. What is the starting concentration of lead in this bayou in units ppb? b. Will lead hydroxide precipitate under these conditions? Why or why not? [Note: Pb(OH)2 has a Ksp of 1.4...
