Why is gold un-reactive enough to be used as nanoparticles?
Why do cells preform endocytosis upon detection of the gold delivery system? What are the chemical receptors active?
Why is does it cause less genetic damage than doing it virally?
Is this system partly designed to change the DNA of...
I'm on the pre-med path. My interest is human enhancement via gene therapy, electronic prosthetics, and both internal/external medical devices.
I'm also interested in the creative business and entrepreneurial ends of these technologies.
Any advice on what specific kinds of internships I should...
The Initial colors of the mixtures in wells A-1 through A-3, A-4, and A-5 were high pink, medium pink, and high pink respectively. When Na2SO4 solution was added to well A-1, the color changed to a light orange. When NaHSO4 was added to well A-3, the color changed to magenta. When the mixture...
If you're saying that the indicator is unreliable, then I don't know how I would tell within these circumstances. The experiment was driven by recording the changes in color depending on the "stresses".
Violet, to my understanding means more OH ions. It turned violet when the temperature lowered. The presence of ions means that MgOH dissociated, which means that it's soluble in colder water.
Unless I'm interpreting my lab results incorrectly.
What do you mean by saturated?
If the indicator isn't telling me anything useful, then how am I suppose to answer the question? It's the only way of telling wether or not MgOH is dissociating that I can think of.
The indicator goes from low (pink) to high (violet) depending on the presence of OH-s. Violet means more of the latter, so I think it means that cold water caused the production OH ions.
MgOH<--> OH + Mg
We did a lab on Le Chatlier's principle. A post-lab question asks wether or not Mg(OH)2 fits the pattern of solids being soluble in warm water.
NaOH was added to MgCl2 to provide the OH. The phenolphthalein indicator within the solution changed color with NaOH's addition--magenta. When heated...
