- Topic: Standardization of acid and base with back titration Note: Include up to 4 decimal places Kindly explain the process Thank you!Compute for the numerical value of the gravimetric factor required to convert the given precipitate into the desired analyte. 1. Magnesium ammonium phosphate (MgNH4PO4) precipitate into phosphorous (as diphosphorous pentoxide, P2O5). 2. Magnesium ammonium phosphate hexahydrate (MgNH4PO4.6H2O) precipitate into nitrogen.If 0.18 mL was used in the blank titration to achieve the same end-point color in the previous question, what is the correct total hardness of the sample? (Picture given is the previous question)
- Explain briefly the meaning of the statement “like dissolves like” note; this is urgent please answer immediately.Submit a clean, dry, and properly labeled 50-mL reagent bottle for your unknown solution. Pipet 20.00 mL of the sample in 250-mL Erlenmeyer flask. Add 5 mL of buffer and 5 drops of indicator. Titrate the solution until it turns light blue. If the titration consumes more than 50 mL of the titrant, dilute the sample accordingly. Compute for ppm of CaCO3 using the following table. Mean Molarity = 2.487 x 10^-3 MBlank correction = 0.015 Formula = V (mL) titrant x Mean Molarity of Titrant x Molecular weight of CaCO3 x 1/V (L) sampleIf a mixture is distilled rapidly, the separation of its compound is poorer than if the mixture is distilled slowly. Please explain why is that so using your own understanding. I don't need a copy-pasted answer from google.
- 1. Find the information for the solubility in water, alcohol (either methanol or ethanol) and acetone (soluble, insoluble, partly soluble, cloudy, clear...etc.), the pH (value or range), the conductivity (value or range), and the flame test (color or colors you should see) results for the compounds listed below: (be as detailed as possible with the information that your write because you will use this information for your experiment in the lab to figure out your unknown) Ammonium Chloride Calcium Nitrate Tetrahydrate Calcium Chloride Dihydrate Sodium Carbonate 2. Figure out (using solubility rules) and write the balanced reaction equations for the precipitation reactions of all the compounds listed above with one of the following compounds: (you should have 4 balanced equations with the states of matter for each compound in the equation). Silver Nitrate Sodium Carbonate Calcium NitrateA student was careful to make and stir all of her standard solutions immediately before measuring their turbidity for her calibration curve. However, she let her tap water solutions sit for 10 minutes prior to measuring their turbidity. If she measured the top portion of the solution, would her experimental sulfate ion concentration be higher or lower than it should be?Twenty sodium salicylate tablets labeled 325 mg were dispersed in sufficient water to make 200.0 ml. A 15.0-ml aliquot of the filtrate was titrated to a bromophenol blue end point in the usual way by 29.11 ml of 0.1000 N hydrochloric acid. Calculate the amount of sodium salicylate in each tablet and, from that, the percentage of the labeled amount. Hint: Use the above formula.
