Sulfur containing compound weighing 4.8670 grams was digested and purified to form H,SO,. A 25.00-mL of 0.0090 M NaOH was added to the collected H2SO4, and the excess base was then back titrated with 13.45 mL of 0.0100 M HCl. Calculate the sulfur content in the sample in parts per million. This problem involves back titration. Write the two chemical equations involved in the analysis. Identify the analyte, “bridging" reagent and titrant. Solve for the mole of the analyte using the titration values and the stoich relationships. One mole of H2SO4 is equal to one mole of sulfur in the sample. Solve for the mass of S then the ppm S.

PLEASE I NEED TO UNDERSTAND HOW TO SOLVE THIS. A 1.000-gram sample of NaOH (39.997 g/mol) which has been exposed to the air for some time (NaOH will adsorb water and CO2 from the ambient air) is dissolved in water and then diluted to 500.00 mL, 100.0 mL of this solution required 38.60 mL of 0.01062 M HCl to be titrated to a methyl orange endpoint (~pH 3). A second 100.00 mL portion is treated with excess BaCl2 and then diluted to 250 mL and filtered. 200 mL of the filtrate required 29.62 mL of HCl to titrate to phenolphthalein (~pH 8-9) endpoint. Calculate in the original sample:a.) the percentage of NaOHb.) the percentage of Na2CO3 (105.9898 g/mol)Make sure you use at least four significant figures for this calculation. Note that the adsorbed CO2 is converted to Na2CO3. The Ksp for BaCO3 (s) is 2.58 x 10-9 (extremely insoluble).
please do all parts of this question thank you! Solid nickel(II) nitrate is slowly added to 75.0 mL of a 0.0636 M ammonium carbonate solution. The concentration of nickel ion required to just initiate precipitation is M. Solid zinc sulfide and solid zinc cyanide are in equilibrium with a solution containing 1.19x102 M ammonium cyanide. Calculate the concentration of sulfide ion present in this solution. [sulfide] = M Solid calcium hydroxide and solid iron(III) hydroxide are in equilibrium with a solution containing 9.05x10 3 M calcium nitrate. Calculate the concentration of iron(III) ion present in this solution. [iron(III)] M
Be sure to answer all parts. Radiochemical techniques are useful in estimating the solubility product of many compounds. In one experiment, 50.0 mL of 0.080 M AgNO3 solution containing a silver isotope with a radioactivity of 74,025 counts per min per mL were mixed with 300.0 mL of a 0.040 M NaIO, solution. The mixed solution was diluted to 500.0 mL and filtered to remove all of the AgIO, precipitate. The remaining solution was found to have a radioactivity of 44.4 counts per min per mL.. What is the Ksp of AgIO,? x 10 (Enter your answer in scientific notation.)
The initial in the unknown analysis is the addition of 6. M HCl. This results in the formation of a precipitate. The solid precipitate is separate from the liquid solution. The solution could potentially contain K+, Ca2+, and Al3+. Next, 3M NH3 is added to the solution to separate the Al3+. This is a result of the fact that the Al3+ forms the hydroxide, Al(OH)3. But Ca2+ also forms the hydroxide, Ca(OH)2. Why does the Ca(OH)2 not separate out with the Al(OH)3?
2. After dissolving the KHP with water, a student noticed some undissolved solid, but continued with the titration as instructed by the procedure. He titrated until the pink color persisted for 30 sec and recorded the volume of titrant required. Preparing for the second determination, he set the reaction solution aside and added some more NaOH to the buret. He was about to pour the reaction solution down the drain, so he could rinse and reuse the flask, when he saw that the pink color had disappeared! a) What happened? b) What can the student do to correct for this erTor and salvage this trial? How should the data sheet be modified to reflect this correction? 3. Another student began adding titrant to the acid solution, but stopped when she suddenly realized that she forgot to add the 3 drops of phenolphthalein. When she did, the solution immediately turned dark red! a) What happened? b) What can the student do to correct for this error and salvage this trial? How should the data sheet…
10.00mL of 0.10M acetic acid were collected in an Erlenmeyer flask, and then diluted to 100mL with distilled water. After that, two drops of indicator were added. Then, the buret was filled with 0.100M NaOH. The titration was started by slowly adding NaOH to acetic acid. (Note: Ignore the volume of the indicator added, as the volume is tiny compared to 100mL.) What is the pH of the solution in the Erlenmeyer flask after adding 10.00mL of 0.100M NaOH? Question 3 options: 7.22 6.9 8.35 7.00

The formula H₂SO4 + 2 KOH --> K₂SO4 + 2 H₂O describes the reaction between sulfuric acid and potassium hydroxide. In the titration done, 20 mL of KOH with an unknown concentration is put into a flask with bromthymol blue indicator. The KOH solution was titrated with a 0.25 M H₂SO4 solution. Three trials were performed and each trial yielded to an endpoint of yellow-colored solution, which is the desired endpoint. After three trials, the following readings were obtained: 15.5, 15.1, and 14.9 mL respectively. Calculate the molarity of Potassium hydroxide. (Answer must be rounded off to 2 decimal places)
