1. The substance to be analyzed – is white, highly soluble in water salt. Addition of diluted sulfuric acid, or hydrochloric acid, or NaOH, or barium chloride, or silver nitrate doesn`t produce any precipitates. Interaction with Nessler's reagent leads to formation of reddish-brown precipitate. Addition of antipyrin in acid medium changes color to red. What kind of substance is this? Explain you answer, provide chemical equations

A student found two bottles of compounds with missing labels. The compounds are either Benzyl chloride or Bromobenzene. To figure out the contents of each bottle, the student put 2 drops of each compound into separate test tubes labeled X and Y and added 1 mL of a mixture of NaI and acetone to each tube. After 45 seconds, the student observed a white color precipitate in tube X, while there was no precipitate formed in tube Y. What compound (Benzyl chloride or Bromobenzene) does tube X contain? Why
In this experiment, your goal is to determine the amount of lead present in a water sample and, if lead is present, to determine whether the level of contamination is potentially dangerous. Preliminary preparation of the sample has resulted in a solid of unknown composition. This solid contains lead (Pb 2+ ) in the form of a water soluble salt and gravimetric analysis will be used to determine the amount of lead present. Step 1. Preparation of precipitating agents : Dissolve a predetermine amount of sodium sulfate in distilled water to produce 100mL with a concentration of 0.175M. Transfer the solution in the burette.Step 2. Obtain 3 10-mL sample of wastewater which contains lead in an erlenmeyer flask.Step 3. Dilute the 10 ml sample with water to 100mL.Step 4. Add an excess amount of sodium sulfate to achieved complete precipitation.Step 5. Filter the solution using a pre-weighed filter paper.Step 6. Collect the precipitates in filter paper and dry in an oven at 105 o C for 3 hrs or…
Which among the statements to promote large precipitates is INCORRECT? Having a dilute solution will keep supersaturation ratio small. Temperature affects particle size during crystal growth. The order of addition of the precipitating reagents may affect induction period. It is better to have a faster rate of nucleation than the rate of crystal growth.
Can you help me find the theoretical yield of precipitate in trial 1 & 2
Anion Test - Chloride (Cl‾) Procedure : Add 5 drops of Cl‾ (NaCl 0.5 M) and AgNO3 0.05 M into a test tube. Check the solubility of precipitate formed in NH3 2 M solution. Results : NaCl after adding AgNO3 obtained white precipitate. Solubility in NH3: 5 drops - did not dissolved 5 more drops - still did not dissolved Excess NH3 - all precipitate dissolved in NH3 solution. What is the Chemical equation involved and Discuss the Chloride test?
Use the data below to determine what cations are present in your unknown sample. You should use both the procedure and the flow chart to make your determinations. Cation lab data Upon adding NaOH the red litmus paper remains red. Upon adding HCl no precipitate is formed Now you add NaOH to your sample followed by hydrogen peroxide and a precipitate forms. You separate this into precipitate 5 and solution 5 To the above precipitate(5) you add HCl and hydrogen peroxide and notice the precipitate has disappeared. You then add ammonia and a precipitate forms. You separate the precipitate by centrifugation into precipitate 7 and solution 7. You then test the precipitate by adding HCl which solublilizies the precipitate, you then add ammonia and a precipitate forms. Upon addition of KSCN a blood red precipitate is formed. To solution 7 you add potassium acetate and acetic acid. You separate the resulting solution into 2 parts. To the first part you add potassium nitrite and a…
In gravimetric methods of analysis, the size and kind of precipitate formed plays an important role on the accuracy of the results obtained. Use Von Weimarn Ratio to explain mechanism of precipitate formations. What is your desired/preferred precipitate for a gravimetric analysis? (refer to the photo below) H 1.01 S 32.07 N 14.01 Cl 35.45 Ba 137.33 P 30.97 Mg 24.31 Na 22.99 Ca 40.08 O 16.00 l 126.90 C 12.01
measure out a 10 mL portion of 10% sodium sulphate into another test tube. making sure to count the drops, use a dropper to add 30% calcium chloride solution. swirl the solution after each drop. continue until a white precipitate occurs. write an equation to explain your observations. which solubility product has the smaller numerical value, that for calcium sulphate or barium sulphate. explain. measure out another 10 mL portion of 10% sodium sulphate into a clean test tube. add 8 drops of 50% sulphuric acid and swirl. count the number of drops (swirl after each drop) of 30% calcium chloride needed to produce a precipitate of calcium sulphate. explain why the number of drops of calcium chloride differs in the two experiments.
The graphic below shows the general procedure for titrating the saturated solution of magnesium hydroxide with hydrochloric acid. Select all of the true statements from the choices below. 1. Obtain a saturated solution of magnesium hydroxide. 0 2. Transfer 30.0 mL to an Erlenmeyer flask using a volumetric pipet. Add phenolphthalein. 3. Titrate to a colorless endpoint using 0.0020 M hydrochloric acid. It is important that the aliquot drawn in step 2 does not contain undissolved magnesium hydroxide solid. For titrations of the saturated solutions at elevated temperatures, the solution must be held at high temperature for the duration of the titration. Hydrochloric acid is the analyte in this titration. The volume of liquid in the buret should be read before and after the titration. At the endpoint of the titration, the solution will turn from colorless to pink.
A compound, X, is dissolved in water. Sodium hydroxide solution and dilute aqueous ammonia were added to different samples of this solution of X. In both, a precipitate formed which dissolved in excess reagent. Compound X could be A copper(II) sulfate. B iron(II) sulfate. C manganese(1I) sulfate. D zinc(II) sulfate.
The sample is dissolved in a mixture containing 10ml of distilled water and 20 ml of dilute HCL.After dilution, add 50 ml of water and 1g of potassium bromide.The mixture is titrated with 0.1N NaNO2 solution . 4 drops of atropine are used as an indicator .At the last point of the titration the color change from red to yellow. Write the reaction that takes place in the nitrometer and the sulfatiazole sample indicator?
