Why did i get the opposite chemical reaction than i was supposed to?Three times i have very successfully and easily used this method to de-oxidize/remove tarnish from my silverThis time, however, instead of getting shinier the silver blackened furtherFor the life of me i have not been able to come up with a reason whyEverything i used to do this was the same as i had previously used (morton salt, armhammer baking soda, boiled water, reynolds aluminum foil, a large glass bowl that had been used successfully for this previously)The silver piece was pure silver and something i had cleaned this way successfully beforeWhat could have caused the piece to oxidize this time but de-oxidize previously??fill a non-reactive bowl with hot/boiling water, line with aluminum foil (shiny side up), and mix in salt and baking soda in a ratio of (1c water : 2tsp baking soda : 1tsp salt -gt; this is the same ratio used previously)Submerge the silver and make sure it touches the aluminum.

Silver tarnish is not silver oxide, but silver sulfideAluminum metal is always covered by a passivating layer of aluminum oxideThe chloride ion reacts with Al2O3 to make AlCl4^-, and exposes fresh aluminum metalThe aluminum metal reacts with Ag2S in a single replacement reaction, which produces silver metal and aluminum sulfideThe sodium ions and bicarbonate ions facilitate the electron transferAs for your particular situationThere should be no reason that the silver should become more tarnishedRepeat the process, but you may want to make the solution more acidic (or at least, less basic)Try adding some vinegar instead of sodium bicarbonate, and use more saltI doubt the small amount of iodine is a problem, but you may also want to used non-iodized salt.
Your rifle will likely be marked somewhere for .223 amunition or nato 5.56 If it is chambered for 5.56 then you can use either amunitionIf it is chambered for .223 then you should only use .223 in it.
If I had to choose one of these? BushmasterIf I had a choice otherwise? SKS or AK Also, you may end up hating the red dotI bought one once and still stuck with irons since.
i have a 10 dollar bb gun built better than the bushmasters are, the smith and wessen ar15 sucks hardcore due to jam and dirt issues get the smith and Wesson OR 5.56 mp15i bought one for my bro 2 months ago get the heavy barrel 16 inch barrel im assuming that your keeping this for a shtf kit or bug out bag as we called em back in the day the 16 in barrel with 6 position stock fits in large duffle the flat top or version you describe is ready for some good cheap red dots from china tracer is no good for your barrel and in shtf you wont have chance on second barrel so get the 1/9 twist and buy 3 or 4 cans of m193 55 grain ball ammo (my bro bought 3 cans for 300 today localy) that barrel with those weight rounds will provide perfect accuracy for the 16 in barrel used (1in groups at 50 yrads) before you buy you rifle find the bullets!!!!!! with 5.56 you can fire 223 but NOT THE OTHER WAY AROUND!!!!!!!!!!!!! so go with the 5.56 for versatility in rounds ALSO AS A SHOOTER ID LIKE TO GIVE A NOD TO THE SKS WHICH WILL ALWAYS BE A BETTER CHOICE FOR SHTF AS MOST OUR EMEMYS USE 7.62X39 AND IT WILL BE EASIER TO FIND IF AMERICA IS EVER OVERRUN BY TERRORIST OR KOREANS OR CHINESSE ALSO THE 7.62X39 IS WAY CHEAPER AMMO STRONGER AND CAUSES SOME SICK WOUNDS AND DID I MENTION AN SKS IS NEARLY JAM PROOF AND ABOUT $300 IN GREAT USED CONDITION
