- For full contact with the acid, nitrile gloves with at least 0.4 mm thickness are required. The thickness of the nitrile gloves in our labs is 6 mil (1 mil = 0.001 in). Will our gloves protect you from full contact with concentrated HCl? Show a calculation to support your conclusions.Many operations in the chemical laboratory use “salting out” in the procedure. What do the purpose of this technique?A top-loading weighs to + 0.5 g. How many mg is that? Please showe step by step solution
- 1.In using a burette, why is it important (a) to rinse it with a little of the solution it is going to contain, (b) to clamp it vertically, (c) to have the part below the tap full? 2. The following procedures were carried out during the titration: (a) The sides of the conical flask were washed down with deionized water. (b) The conical flask was frequently swirled or shaken.What volume of 0.10 M H2C2O4 would be required to remove the rust stain weighing 1.0 grams?Give detailed Solution no need Handwritten

Note: Please include the complete solution. Thanks!You found two bottles in the laboratory labeled X and Y. The instructor said that these bottles contain strontium chloride and sodium chloride. You were tasked to identify bottles X and Y and what salt is contained in each bottle so that it can be properly labeled. Prepare a procedure on how you would be able to identify the salts in each bottle using a flame test and how the results will be interpreted.
- Estimation of Dissolved Oxygen I want analysis and Precautions for this experimentB. 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…This is not graded, do # 8.
