If the silver chloride is not dry when its mass is determined will the calculated percent of. silver in the alloy be too high or too low Explain.?
If the silver chloride is not dry when its mass is determined, the calculated percent of silver in the alloy will be too low. This is because the presence of water in the silver chloride sample will add extra mass to the compound, leading to an underestimation of the actual silver content in the alloy.
How could you make a pure sample of solid silver chloride starting with silver nitrate solution?
Add hydrochloric acid to silver nitrate and stir well to ensure it is all reacted. Silver chloride will precipitate out and is fairly insoluble. Filter the solution and collect the filtrate on the filter paper. Rinse a few times with water to wash off the excess acid. Dry the filtrate in the oven. The result is pure silver chloride. Note this is sensitive to UV light, so this is best done in a dark room under a red lamp.
How do you obtain pure and dry sample of sodium chloride salt?
To obtain a dry sample of salt the process of the evaporation of salty water must take place . Generally salt is produced in the Salt pans that are located close to the coast . The suns energy is used to evaporate ,leaving the residue behind . This residue is a mixture of several salts not just NaCl. To obtain a pure form of salt it is processed by industries and is pure Sodium Chloride.
How do you prepare .9 sodium chloride solution?
You take 1.00 mole NaCl, this is 58.45 grams dry substance NaCl, and add (while dissolving) up to 1.00 L water (so you'll need about 0.95 L -LESS than 1.00 L- of water).
How do you separate lead sulphate and lead chloride?
Lead chloride dissolves in hot water, whereas lead sulphate does not. Mix the sample with hot water and filter off the lead sulphate, then evaporate the water and dry the solid left behind to recover the lead chloride.

How would you prepare a sample of pure dry ammonium nitrate?
To prepare a sample of pure dry ammonium nitrate, dissolve ammonium nitrate in water to form a saturated solution, then allow the solution to cool and crystallize. Filter and dry the resulting crystals to obtain pure dry ammonium nitrate.

How you prepare plant sample in lab analysis?
just dry the plant sample and then dry it in 50 degree centigrades for 72 hrs and then powder it. seive it use that powder for the analysis.
Why excess barium chloride is added to the filtrate in the preparation of a dry sample of barium sulphate?
Barium chloride in excess is added to be sure that the reaction is complete.
How do you prepare mercuric chloride paper?
To prepare mercuric chloride paper, dissolve mercuric chloride in distilled water to make a solution. Then, soak filter paper in the solution until it is fully saturated. Finally, let the paper dry completely before use.
How you would prepare a sample of solid sodium chloride from sodium hydroxide solution and hydrochloric acid?
Add concentrated solution of Hydro chloric acid to the solution of sodium hydroxide till mixture becomes neutral (checked by litmus) then heat the mixture , when a little amount of water is left allow to cool the mixture , the crystals of sodium chloride settelted down filter and dry the crystals.
How do you prepare a pure sample of dry carbonate using solution of ammonium carbonate?
To prepare a pure sample of dry carbonate using a solution of ammonium carbonate, you would need to first evaporate the solution to dryness to obtain solid ammonium carbonate. Then, heat the solid in a crucible to decompose it into ammonia, carbon dioxide, and water. Finally, collect the carbon dioxide gas and purify it to obtain the pure dry carbonate.
WHY SILVER NITRATE IS SECONDARY STANDARD?
Silver nitrate is often used as a secondary standard in analytical chemistry because it is easy to prepare and has a high purity. It is also stable in dry form and can be stored for long periods without significant degradation. Additionally, its reaction with halide ions forms insoluble silver halides, making it a useful reagent for titrations involving chloride, bromide, and iodide ions.
