0.3926 g of salicylic acid is dissolved in water and made up to 250.0 mL in a volumetric flask. Then, 4.00 mL of this solution is pipetted into a 50.0 mL volumetric flask and diluted with water to the mark. What is the final salicylic acid concentration?
0.3856 g of salicylic acid is dissolved in water and made up to 250.0 mL in a volumetric flask. Then, 3.00 mL of this solution is pipetted into a 50.0 mL volumetric flask and diluted with water to the mark. What is the final salicylic acid concentration?
3. (5 pts) A solution was prepared by transferring 0.661 g of KSO to a 250.0-ml volumetric flask (container 1) and adding water to the mark. A sample of this solution of volume 1.000 ml was transferred to a 500.0-ml volumetric flask (container 2) and diluted to the mark with water. Then 10.0 mL of the diluted solution was transferred to a 250.0-ml flask (container 3) and diluted to the mark with water. What is the final concentration of K2SO4...
The recommended procedure for preparing a very dilute solution is not to weigh out a very small mass or measure a very small volume of stock solution. Instead, it is done by a series of dilutions. A sample of 0.8521 g of KMnO4 was dissolved in water and made up to the volume in a 500.0−mL volumetric flask. A 2.000−mL sample of this solution was transferred to a 1000−mL volumetric flask and diluted to the mark with water. Next, 10.00...

Write the complete ionic and net ionic equations for each of the following reactions: To write complete ionic equations and net ionic equations follow the steps below: (I) Write the molecular equation and balance it. (II) Determine the state of each substance(gas, liquid, solid, aqueous). Use the solubility rules! (III) Write the ionic equation by breaking all the soluble ionic compounds (those marked with an (aq) into their respective ions. (IV) Write the net ionic equation by removing the spectator...
The formate ion, (CHO2-), is related to the acetate ion and forms ionic salts with many metal ions. Assume that 11.874 g of M(CHO2)2 (where M represents the atomic symbol for a particular metal) are dissolved in water. When a solution of 0.300 M sodium sulfate is added, a white precipitate forms. The sodium sulfate solution is added until no more precipitate forms, then a few excess milliliters are added. The precipitate is filtered, washed, and dried. It has a...
