The color is from sodium, not from Cl or Nitrate - NO3.
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.
Anything with lead ions and anything with chloride ions. So, for example, lead nitrate and sodium chloride. Getting lead into solution is actually the tricky part here; most lead compounds are not particularly soluble.
The word equation for silver nitrate plus sodium chloride is "silver nitrate + sodium chloride → silver chloride + sodium nitrate". The symbol equation for this reaction is "AgNO3 + NaCl → AgCl + NaNO3".
When sodium chloride and silver nitrate react, they form silver chloride precipitation and sodium nitrate in solution. This is a chemical change as new substances are formed with different properties from the original reactants.
Mercury Nitrate: Hg(NO3)2 Sodium Chloride: NaCl
The color (yellow) is due to the metal ion (sodium), the other element does not participate.
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.
The color of a flame is determined by the specific metal ions present in the substance being burned. In this case, both sodium chloride and sodium nitrate contain sodium ions, which are responsible for the yellow color observed in the flame test. When these substances are burned, the sodium ions are excited and emit yellow light, resulting in the same color of flame.
Sodium chloride and and sodium nitrate doesn't react.
Anything with lead ions and anything with chloride ions. So, for example, lead nitrate and sodium chloride. Getting lead into solution is actually the tricky part here; most lead compounds are not particularly soluble.
white/gray
The reaction is:LNaCl + AgNO3 = AgCl + NaNO3The white precipitate is silver chloride.
Sodium chloride is NaCl. Ammonium nitrate is NH4NO3.
When aqueous solutions of silver nitrate and sodium chloride are mixed, a white precipitate of silver chloride immediately forms due to a chemical reaction between silver ions from silver nitrate and chloride ions from sodium chloride. Silver chloride is insoluble in water, which causes it to form a solid precipitate.
Sodium nitrate (NaNO3) is more soluble in water compared to sodium chloride (NaCl). Sodium nitrate has a higher solubility due to the presence of more polar nitrate (NO3-) ions in the compound.
The silver chloride, as a white precipitate is obtained:AgNO3 + NaCl = AgCl + NaNO3
When barium chloride and sodium hydroxide are added to copper nitrate, a white precipitate of barium nitrate forms due to the reaction between barium chloride and sodium nitrate. The copper ions in the solution remain unchanged as they do not react with barium chloride or sodium hydroxide under normal conditions.
