1. How do you know when a solution is saturated?
a) If you are given a solution that is 350 ppm Zn, how would you make 250 mL of a solutions that is 120 ppm Zn? b) What is the concentration of the original solution of Zinc ions (350 ppm) in micrograms per mL of solution? The solubility of calcium carbonate in cold water (25 degree C) is 0.0014 g/100mL Calculate the concentration in Molarity of a saturated solution of calcium carbonate.
How would you determine the concentration of an unknown NiCl2 solution, if you have enough NiCl2 as a powder, a Spectrovis Plus and all the necessary equipment? (Absorption maxima is observed at lamda = 610 nm)
1) Explain how saturated NaCl solution would help draw the water away from the organic layer in the emulsion layer. 2) You have a solution of 30 mg of caffeine dissolved in 100 mL of water. The partition coefficient for aqueous caffeine extracted with Dichloromethane (CH2C12) is 4.6. Show all work for the following calculations: a. Calculate the total mg extracted by using a single 30 mL portion of dichloromethane. b. Calculate the total mg extracted by using a three...
How would you determine the molality of a solution that is 45.0% (m/m) NaNO3(aq), and has a density of 1.37 g/mL? I'm a bit confused. An explanation with work provided would be super helpful, thank you.
Determine how you would make 100mL of a stock copper solution at 300ug/mL if using copper (II) nitrate hexahydrate.

As a small business owner facing saturated domestic markets, how would you approach foreign markets? Develop a strategic plan outlining how you would research markets, get your product to potential customers, handle the financing side of the business, and grow your sales. Include information on what resources are available to help with this process.
A saturated solution of manganese(II) hydroxide was prepared, and an acid–base titration was performed to determine its Ksp at 25 °C. The endpoint was reached when 75.00 mL of the manganese(II) hydroxide solution was titrated with 2.00 mL of 0.0040 M HCl solution. What is the Ksp of manganese(II) hydroxide?
