I use 70% strength Nitric. You will need low heat to get the reaction going.

Brown fumes will appear. YOU MUST NOT BREATH THESE! Place the silver-containing object into the acid and wait until it dissolves. Let the acid cool down.

Place a copper bar into the acid. Don't use wire or sheet as pieces will

break off and fall to the bottom of the container. You will see a carpet of Silver forming on the copper bar.

Give the bar a shake every now and then. It wll fall to the bottom. Leave it for 24 hours. The spongy carpet left at the bottom is your silver.

Pour off the acid carefully and wash your silver thoroughly

in distilled water. You will have 99% pure Silver. Melt and enjoy!

What is the pH of a solution that contains 1.32 grams of nitric acid dissolved in 750 milliters of water?

Two steps. Find molarity of nitric acid and need moles HNO3.Then find pH. 1.32 grams HNO3 (1 mole HNO3/63.018 grams) = 0.020946 moles nitric acid ------------------------------------- Molarity = moles of solute/Liters of solution ( 750 milliliters = 0.750 Liters ) Molarity = 0.020946 moles HNO3/0.750 Liters = 0.027928 M HNO3 ----------------------------------finally, - log(0.027928 M HNO3) = 1.55 pH ==========( could call it 1.6 pH )


How can you test to see if its real silver?

Silver jewelry has become the most typical and excellent term of fashion standards. It suits with every outfit and can be worn for all occasions. From weddings, business lunches, a day of shopping with friends to evening dates, silver accessories will look great. New styles incorporating larger pendants on sterling chains are a hot trend currently. In Sterling silver chain jewelry fashion there are few other classic styles such as Sterling silver chains for pendants, sterling silver bead chain, silk cord, sterling silver chain necklaces, like silver anklets, silver bead chain, snake chain, box chain and gold plated chain. This jewelry is an investment in quality that stands the time of time. A few pieces can accessorize the wardrobe beautifully. Sterling silver chains jewelry designs on ethnic and traditional as well as modern gemstone silver jewelry. Quality jewelry is made with the best materials. Its value is not compromised by using inferior metals or shoddy craftsmanship. When purchasing sterling silver jewelry, you want to be assured that it is authentic. You want to feel confident that your piece is the quality you expect for the price that you paid. Consumers are haggard up with the cheap imitations of jewelry that have flooded the market searching for the real silver chains by the inch. Steps for finding the real silver jewelry are, Nitric acid test can be made to determine whether the piece is real or fake. This test can be done by you but it is advised to be done by an expertise. It is done by vigorously rubbing a certain portion of the silver jewelry that you want to test. Try to pick an area that is not noticeable. Then apply a few drops of nitric acid onto the scratched surface. After a while check whether the liquid turns either green or grey. If the liquid turns green, the item is only silver plated. If it turns a cloudy grey color, this piece is guaranteed sterling silver. Is your accessory getting attracted by magnet? Only iron and iron alloys stick to a magnet. The base metal in plated jewelry is usually a copper alloy that contains various other metals such as tin and nickel whereas sterling silver is made 92.5% pure silver mixed up with only 7.5% of alloy. None of the metal will be chipped away to expose a possible secondary metal underneath. Check for the marks such as "sterling" or the number 925 for sterling silver. 925 refer to 92.5% silver which is considered sterling. The location of the stamp may vary depending upon the type of jewelry. The stamp on necklaces is usually on the clasp. It is most important in checking cheap sterling silver necklaces. On rings and bracelets, the stamps are usually scraped inside of the sterling silver jewelry piece. By taking the appropriate steps, you can be assured that your silver jewelry is both genuine and high quality. I hope this helps.
