- Please don't provide hand writtin solution..... I need Explation solution and step solution...During the lab procedure a filtered pipette was used to measure out 1.0 mL of the saturated salicylic acid solution. The filter had a bit of cotton on the tip. What component of the mixture was being filtered out?Hi! Please provide a complete and neat solution. Thank you!
- Please help me answer this. In a test tube, 5 mL of cooking oil and 5 mL of detergent solution were added and shaken.The two did not mix. Explain 3 properties on the cleansing action of soap/detergents.PLEASE MAKE THE SOLUTION COMPLETE, UNDERSTANDABLE AND READABLE. Please write the solution in the paper.1. Obtain a 50-ml burette, 5-mL volumetric pipette and a pipette bulb from the stockroom. Setting up the burette and preparing the NaOH 2. Rinse the inside of the burette with distilled water. Allow the distilled water to drain out through the tip in order to ensure that the tip is also rinsed. 3. Now rinse the burette with a small amount of NaOH (aq). To do this, add about 5-mL of NaOH (aq) to the burette, then twirl the burette on its side (over the sink) to rinse its entire inner surface. Then allow the NaOH (aq) to drain out through the tip. M Burette Pipette 4. Fill the burette with NaOH (aq) up to the top, between 0-mL and 5-ml. Use a funnel to do this carefully, below eye-level, and preferably over the sink. After this you will need to flush the tip of the burette - your instructor will show you how to do this. Now measure the volume at the level of the NaOH precisely, and record it as the "Initial Burette Reading" on your report. Also record the exact molarity of the NaOH (aq),…
- Procedure A: Molarity (M=g/MM/L) Step 1. Place one-eighth of a teaspoon (this weighs approximately 0.5 grams) of NaCl (table salt) in the graduated cylinder provided. Then add distilled water to that graduated cylinder until the level of the water reaches 45.00 mL. Mix thoroughly about 1 minute. Pour solution into a somewhat clear cup. Remember what this looks like for Procedure B. Questions: Is this a saturated solution? Why or why not? Take a picture and insert a picture (compress your image) of your solution here. Save this solution for Step 2. Calculations: Determine the Molarity of this solution using the formula M = g/MM/L. You know the grams (one-eighth of a teaspoon weighs approximately 0.5 grams), look up the Molar Mass of NaCl, and convert your mL to L to solve the problem.) Show your calculations for Molarity here.
