You are making a 1L solution that you want to be buffered with ammonia and ammonium. However ammonia is a gas that is difficult to dissolve directly in water with good precision. Instead you will start with ammonium chloride and add sodium hydroxide which will react with the ammonium to form ammonia. Which of the following combinations will give you the optimal buffered solution?

54 grams ammonium chloride and 108 grams sodium hydroxide

54 grams ammonium chloride and 54 grams sodium hydroxide

54 grams ammonium chloride and 40 grams sodium hydroxide

54 grams ammonium chloride and 10 grams sodium hydroxide

When an excess of sodium hydroxide is added to an aqueous solution of ammonium chloride, gaseous ammonia is produced: NaOH(aq) + NH4Cl(aq) → NaCl(aq) + NH3(g) + H2O(ℓ) Suppose 3.68 g ammonium chloride reacts in this way at 30°C and a total pressure of 0.9884 atm. At this temperature, the vapor pressure of water is 0.0419 atm. Calculate the volume of ammonia saturated with water vapor that will be produced under these conditions, assuming no leaks or other losses of...

In experiment five, the "Identification of Ions in Salts", you will use a series of reactions to identify a cation in one unknown and a cation-anion in another unknown. In this experiment primarily precipitation reactions or dissolving of precipitates will be used. The color and texture of the precipitate will be important to observe. In the identification of the anion the formation of a gas will be used to help ID the anion and a flame test will be used...

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks! Background In this lab, we will determine the amount of alcohol (ethanol), C2H5OH, in a commercial vodka...
