Why is it less desirable to wash AgCl precipitate with aqueous NaNO3 than with HNO3 solution? (Select all that apply.) A) HNO3 evaporates during drying. B)HNO3 is nonvolatile and will lead to a high mass for the precipitate. C )NNO3 is and will lead to a high mass for the precipitate. D)NaNO3 evaporates during drying.

Answer should be 24%, I keep getting 117% which is wrong obviously. What am I doing wrong

Please answer all parts

Which of the following would keep the relative super saturation at minimum during precipitation? 1. OElevated temperature. 2. ODilute solutions. 3. OSlow addition of precipitating agent with good stirring 4. O All of the above.

Circle all that are correct.A) PbCl2 is a precipitateB) Ba(NO3)2 is solubleC) AgCl is solubleD) AlCl3 is soluble

Give detailed Solution with explanation needed..show work..don't give Handwritten answer..don't use Ai for answering this

How much precipitate will be recovered after excess CaCl₂ Hint: 1. Write out the balanced chemical equation. 2. Identify the precipitate 3. THEN develop your plan and calculate 19 grams 2.7 grams 3.6 grams after excess CaCl₂ solution is mixed with 25 mL 0.75 M AgNO3?

In the gravimetric determination of sulfate in a 0.5613 g sample of pure NazSO4, a BaSO. precipitate weighing 0.4309 g was obtained. The weight of the precipitate was smaller than the theoretical one. since some BaSO& was converted to Bas during the heating process. (a) Calculate the percent of Bas in the precipitate (Hint: best to solve algebraically) (b) Calculate the percent error of the analysis (Hint: compare calculated with weight stated in problem).

Question 1 Answer all the question below, 1. Phosphate ion (PO4) is determined by converting it to ammonium phosphomolybdate (NH4)4PO4.12MOO3 (MW=18765) precipitate. If 0.2711g sample produced 1.1682g of precipitate. Calculate the % of (PO4). 2. In one gravimetric analysis to determine the % of Mn from the manganese ore, 0.6443g manganese ore was found to yield 0.4211 g Mn304. Calculate the % of Mn in the ore. 3. In one gravimetric experiment, 0.4162 g of AgCl is obtained from a 0.9110g sample of silver ore. Calculate the percentage of Ag in the ore.
