Sodium Chloride (or NaCl) would not cause burns, common table salt is NaCl and this is ingested qute regularly! Sodium Nitrate would mildly irritate your hands, to a similar degree that turpentine would. If you need information on the safety of chemicals, you should try performing a search of 'chemical name MSDS'. replacing chemical name with the chemical name. (obviously!) MSDS stands for material safety data sheet, and lots of big companies produce these with the chemicals as a guide! I hope this was useful!
The color is from sodium, not from Cl or Nitrate - NO3.
The (yellow) sodium color is the same in all.
Silver Nitrate + Sodium Chloride --> Silver Chloride + Sodium Nitrate AgNO3 + NaCL --> AgCL + NaNO3
The yellow color of the flame is due only to sodium.
The color (yellow) is due to the metal ion (sodium), the other element does not participate.
copper chloride
no reaction, the solution stays clear. I've personally performed this experiment.
Because important is the metal (sodium) and his spectral lines.
No. While chemically sodium nitrite is a salt, the salt you eat, table salt, is sodium chloride.
Because the color is due to the sodium. All of them have sodium, all of them give the same color. Technically nitrogen, oxygen, and chlorine have spectral lines as well; it's just that sodium's are much more prominent.
No. Ammonium nitrate contains the ammonium ion NH4+, and has the formula NH4NO3, and sodium nitrate has the formula NaNO3.
No
