- Volumetric pipettes are designed to deliver a precise amount of liquid, but only if you a. submerge the end of the pipette into a solution you are delivering. b. allow the pipette to drain freely, and leave any residual solution in the pipette. c. hold the pipette at a 45 degree angle and ensure that all the liquid is delivered.Which of the following description(s) are improperly used related to the process of filtration? Select all that apply Group of answer choices - you can pick more then one: "I filtrated my product" "At this step I filtered" "There was solid leftover in the filtrate" "Filtering was an important part of the experiment"Why does the separation apparatus must be vented after several inversions? a to make the stopcock tighter b to release built-up pressure c to reduce liquid solvent d to aid the separation
- Before Investigating the scene the technician must dilute the luminol solution to a concentration a 2.00 × 10-2 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of luminol are present in 2.00L of the diluted spray?When I balance it out with 2,15,10 and 10. Does not work I'm confused pls help.What is the control variable, independent variable, dependent variable for the filtration process.
- State and explain one possible source of random error whilst using a pipette.Your answer should justify why this is a random error.I tried to ask the question previously as I’m trying to study for my exam with a sample lab off of YouTube and I’m unsure why it was rejected. .
