Why 1M of HCL is used in Dnase test?
what is the role of HCL in the DNase experiment
Why NaOH and HCL were added in liquid-liquid extraction experiment and please write the equation?
HCL to acidify the mixture
Show me a diagram of funnel experiment in the preparation of hcl?
a seperating funnel is used to seperate mixtures
Why concentrated sulfuric acid and not hydrochloric acid used in this experiment?
because hcl contains cl2
If 18mL of 1.0M HCl is used in the experiment how many moles of hydrogen ions are available for the reaction?
1.0 M = x mol HCl /.018 L of solution x = .018 mol HCl Since HCl --> H+ and Cl- in a 1 to 1 to 1 ratio, then you will also have .018 mol of H+ in solution.

How we can use acetocarmine to stain the onion root tip cells?
take the root tip (about 1 cm )and put it in dil. HCL solution for ten min. take the tip out and put in acetocarmine stain for 1min. take out the root put it in water bto remove extra stain .

Experiment in acid base and salt?
An example; preparation of sodium chloride in laboratory: NaOH + HCl = NaCl + H2O

What is the disadvantage of using HCl in an experiment for denaturing proteins apart from the fact that it is dangerous?
HCl (Hydrochloric Acid) is highly acidic (it is stomach acid!). Therefore, HCl will actually damage and potentially destroy the proteins, so it is not a great idea to denature proteins using something that will destroy them
How would conduct an experiment to prove single replacement occurs when Zn and HCl are combined?
get some Zn metal (or use a new penny) and get some HCl. You will see the H2 gas bubble and the Zn will corrode
What is the purpose of Hydrochloric acid in mitosis slide?
HCl is used to destroy the substances that unite the cells so that the cells spread easily and you can see one layer of cells on your slide.

How do you fix onion root tips for squash prepration?
follow this procedure.. 1.Collect two onion root tips and trim so that you have about 2 mm of the very tip. 2.Soak the tips in a few drops of 1 M HCl in a watch glass for about 10 min. 3.Transfer the tips to a few drops of acetocarmine stain for about 15 min. 4.Transfer one tip to a few drops of water on a slide. Lower a cover slip onto the tip and press it down gently so that the tip squashes out to about 7 mm (1/3 inch) around. 5.Look for mitoses under high power (X40) or under oil immersion (X100) (If this fails for any reason try your other root tip)
