    2 KNO 3 + 4 Al + S → K 2 S + N 2 + 2 Al 2 O 3. The composition is approximately 59% KNO 3 : 31.6% Al : 9.4% S by weight for the reactants of the above stoichiometrically balanced equation. For best results, "German Dark" aluminum should be used, with air float sulfur, and finely ball milled pure potassium nitrate. The finished mixture should ...

    Corrodes magnesium and aluminium, incompatible with them. Yellow Sodium chloride: NaCl Loses hygroscopicity on heating. Corrodes metals. Yellow Sodium oxalate: Na 2 C 2 O 4: Non-hygroscopic. Slightly reacts with magnesium, no reaction with aluminium. Yellow Sodium nitrate: NaNO 3: Also acts as oxidizer. Bright flame, used for illumination ...

  4. Magnesium nitrate - Wikipedia

    en.wikipedia.org/wiki/Magnesium_nitrate

    Magnesium nitrate reacts with alkali metal hydroxide to form the corresponding nitrate: Mg(NO 3) 2 + 2 NaOH → Mg(OH) 2 + 2 NaNO 3.. Since magnesium nitrate has a high affinity for water, heating the hexahydrate does not result in the dehydration of the salt, but rather its decomposition into magnesium oxide, oxygen, and nitrogen oxides:

    Reacts with magnesium when wet and liberates heat and ammonia, can self-ignite. In contact with potassium nitrate (e.g. in black powder) produces potassium perchlorate and hygroscopic ammonium nitrate; no such reaction with sodium nitrate.
