If it's pure, then no. If it's not pure, maybe.
Any bath soap contain a little sodium chloride.
A normal vinegar didn't contain sodium chloride.
The only pure salt that has any sodium chloride {note correct spelling} in it is the salt sodium chloride itself. Many mixtures of salts could contain sodium chloride in the mixture.
Any soil contain more or less sodium chloride.
Any soil contain more or less sodium chloride.
The residue from the reaction between ferric chloride and sodium hydroxide would likely contain iron hydroxide as a major component, with sodium chloride also present because of the initial reactants. The specific composition would depend on the stoichiometry of the reaction and any other impurities present in the starting materials.
Any reaction occur.
FeCI3 +3NaOH ->Fe(OH)3 +3NaCIIron (III) chloride + Sodium Hydroxide ---> iron (III) hydroxide + sodium chloride
The sodium chloride solution in water is neutral (pH=7).
"Common salt", with the chemical formula NaCl, does not contain any hydrogen. The much larger chemical class of "salts" includes some examples that do contain hydrogen, for example the ammonium salts.
By knowing or learning that the bright yellow lines observed with sodium chloride occur with all other compounds of sodium but not with any other compound of chlorine that does not contain sodium.
Sterile water is pure water that does not contain any additives, while sodium chloride is a salt solution made by dissolving salt in water. Sterile water is commonly used for irrigation and dilution purposes, while sodium chloride is used for intravenous infusions and to replenish electrolytes.
