Which of the following is true when preparing solutions? a. Make sure that the solvent and reagents are contaminated. b. When diluting to the mark using a volumetric flask, the upper meniscus and mark should be at eye level. c. If amount added is over the mark, you cannot just take out the excess liquid and preparation must be repeated. d. After mixing the contents of the flask and the level of the meniscus seems lower than the mark, add more diluent.

Why is important to allow the saturated solution to cool down slowly during the recrystallization?
When conducting a recrystallization what should generally be true when comparing the compounds melting point compared to the boiling point of the solvent? Explain why this is so.
B. Determining the Composition of a Mixture of Sodium Chloride and Sodium Nitrate Partner I Prepare a solution of sodium chloride + sodium nitrate and indicator. Obtain a dropper bottle of potassium chromate (indicator) solution. To a clean and dry 125 mL Erlenmeyer flask, add about 40 mL of water and 8 drops of indicator solution. Weigh out approximately 0.05 grams of sodium chloride + sodium nitrate solid and record its exact mass. Dissolve the solid in the solution from step 1, stirring with a stirring rod to ensure complete dissolution. Determine and record the total mass of the Erlenmeyer flask and solution, noting the balance that you use to weigh. Rather than measuring the volume of silver nitrate solution added as in Part A, we will measure the mass of titrant added and make use of the weight-percentage concentration of silver nitrate in calculations. Prepare the silver nitrate solution. Obtain about 15 mL of 1.70% w/w silver nitrate solution in a 50 mL beaker. Designate a…
Which statement about liquid-liquid extraction is not correct? * A- A solvent must be available that is miscible with the solution containing the substance to be extracted. B- The solvent used for extraction must have a good ability to dissolve the desired substance. C- The denser solution forms the bottom layer in the extraction funnel. D- The extraction funnel must be vented during the extraction procedure to prevent excessive build-up of pressure inside the extraction funnel. E- All these statements are correct.
Why do we have to measure the boiling point of distilled water during this experiment?
Isopropanol and water are miscible, meaning they can be combined in any ratio. So why were they immiscible in this experiment? In other words, why does the presence of sodium chloride reduce the solubility?
Why can we use a water-ethanol mixture but not a water-hexane mixture as a recrystallization solvent
If you choose a serial dilution—what would you do? Assume that you begin with a 1.0 M solution. You perform a 50% serial dilution to prepare four additional standards. What are the final concentrations of these new standards? Show a sample calculation.
What should be the volume of concentrated acetic acid that should be measured to prepare 100 mL of solution with a concentration of 0.2 mol/L? (Data: T = 99.7%; d = 1.05 g/cm³; MM = 60.052 g/mol).
What properties should ideally be possessed by a recrystallization solvent?
if i want to dilute 30 L ofa 1.5 M FeSO4 solution to a 0.3 M FeSO4 solution how much of the solvent will i need to add ?
In general terms, please describe how to carry out a recrystallization. Just give the steps that should be used to recrystallize something.
