For convenience, one form of sodium hydroxide that is sold commercially is the saturated solution. This solution is 19.4 M, which is approximately 50% by mass sodium hydroxide. What volume of this solution would be needed to prepare 3.74 L of 4.02 M NaOH solution? Volume = mL An aqueous solution is to be prepared that will be 6.82% by mass ammonium nitrate. What mass of NH4NO3 and what mass of water will be needed to prepare 1.25 kg of...
Standard solutions of calcium ion used to test for water hardness are prepared by dissolving pure calcium carbonate, CaCO3, in dilute hydrochloric acid. A 1.579 g sample of CaCO3 is placed in a 150.0 mL volumetric flask and dissolved in HCl. Then the solution is diluted to the calibration mark of the volumetric flask. Calculate the resulting molarity of calcium ion. Molarity M For convenience, one form of sodium hydroxide that is sold commercially is the saturated solution. This solution...
Sodium hydroxide is extremely soluble in water. At a certain temperature, a saturated solution contains 567 g NaOH(s) per liter of solution. Calculate the molarity of this saturated NaOH(aq) solution. concentration: If 8.67 g of CuNO, is dissolved in water to make a 0.250 M solution, what is the volume of the solution in milliliters? volume: mL
You need to prepare a 2.10 M solution of sodium hydroxide (molar mass of sodium hydroxide= 40.00 g/mol), but you only have 10 mL graduated cylinder and a 25 mL beaker. Complete the following sentences regarding the concentration of the prepared solution. 1. In order to prepare 10.0 mL (0.0100 L) solution of 2.10 M sodium hydroxide, a mass of ?? would be required. 2. When the solute and a total of 10.0 mL of water are both added into...

Preparation of 0.05 M Sodium Hydroxide (NaOH): In a clean, 2-liter plastic bottle place approximately 1.5 liter of deionized water and add a sufficient volume of 50 wt% sodium hydroxide solution (density = 1.52 g∙mL–1) to produce an approximately 0.05 M solution? How do I prepare this solution?
The mass of magnesium hydroxide that is dissolved in 125 mL of a saturated solution is grams. The mass of lead carbonate that is dissolved in 150 mL of a saturated solution is grams. The volume of water needed to dissolve 0.0606 grams of calcium chromate is L. Assume no volume change upon addition of the solid.
In this procedure it is important to store the sodium hydroxide, NaOH, solution securely capped to avoid evaporation of water. 1. What would the impact of leaving the plastic bottle of sodium hydroxide open to the atmosphere and allowing some of the water to evaporate be on the concentration of the solution. Would the concentration be higher, lower, or unchanged. Provide an explanation for your answer. 2. If the sodium hydroxide, NaOH, solution was not re-standardized after some of the...
