I'm confused by your question. Can it be done? Yes. Can I do it personally? Yes. Do pharmaceutical companies do it every day? Yes. Are you asking if it can be done stereo-selectively? As far as I know, you can get the S isomer, which is the most biologically active form. It is sold as Ketanest S. Maybe elaborate more on your question...
Free base ketamine is a liquid. However, ketamine is typically issued as the hydrochloride salt, which is a white powder. Often, ketamine HCl is dissolved in water to produce a clear solution.
HCl is a pure substance because it is a compound. Pure substances consist of elements and compounds.
0.5 M HCl means the concentration of hydrochloric acid is 0.5 moles per liter of solution. To calculate this, you need to use the formula: moles = molarity x volume (in liters). So, if you have, for example, 1 liter of 0.5 M HCl solution, you would have 0.5 moles of HCl in that solution.
To prepare a 10mM solution of Tris-HCl, you would weigh out the appropriate amount of Tris-HCl powder using a balance and dissolve it in water to make a final volume of solution. For example, to make 1L of 10mM Tris-HCl solution, you would need to dissolve 0.121g of Tris-HCl in 1L of water.
No, in pure liquid HCl, the molecules exist as HCl molecules and not as separate ions. It is only when HCl dissolves in water that it dissociates into its constituent ions (H+ and Cl-) due to the polar nature of water molecules.

It comes as pure white crystalline powder. Cocaine HCl (or Cocaine Hydrochloride) is your answer.

i dont knw
Well that is somewhat loaded it is pure in and of itself, it can be impure but it can be pure. Adding other gasses to it (its a gas at room temp when not dissolved in water to make the acid) would make it impure. Adding things to the acid which do not react could also be seen as impurities. Bear in mind there is no way to make the actual molecule impure by say making HOCl because this is no longer HCl but a different compound (hypochloric acid)
To make a stannous chloride solution, dissolve stannous chloride dihydrate (SnCl2•2H2O) in water at the desired concentration. The solution can be heated to help dissolve the compound faster. It is important to take necessary safety precautions, as stannous chloride can be corrosive and toxic.

Hydrochloric acid (HCl) in its pure form is a colorless liquid. It may appear slightly yellow due to impurities or degradation.
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
When hydrochloric acid (HCl) reacts with iron powder, the iron oxidizes to form iron(II) chloride (FeCl2) and hydrogen gas (H2) is released. This reaction is a typical metal-acid reaction known as a single displacement reaction. The iron powder will dissolve and you will observe bubbling as the gas is released.
