NITRIC ACID SUBSTITUTE (sodium nitrate) 4ozs

Nitric acid substitute to be mixed with hydrochloric acid. This is used to dissolve gold for later precipitation. Instructions using JSP® NITRIC ACID SUBSTITUTE a) Dissolve 80 grams (2.8 oz) of JSP® Nitric Acid Substitute in 50 milliliters (1.7 fl oz) of water. Start by portioning out your JSP Nitric Acid Substitute into a small glass mixing container. Then, pour in all of the water at once. Swirl the mixture around inside the container to help it dissolve faster. Itz important to use distilled water rather than ordinary tap water. Most tap water contains traces of other chemicals that can throw off the composition of the acid you produce. b) Add 100 milliliters (3.4 fl oz) of JSP® hydrochloric acid. Measure the acid in a graduated cylinder to ensure that you??re using just the right amount. Transfer the acid to the JSP® Nitric Acid SUBSTITUTE solution carefully, taking caution not to let it spill or splash. Swirl the contents of the container again to mix your chemical components. Itz a good idea to work under a fume hood or set up your equipment in a well-ventilated open area, as your test materials will emit strong fumes when brought into contact with the acid. Warning: Always wear gloves and safety goggles when working with acids. Hydrochloric acid in particular is highly corrosive??without proper protection, getting even a small drop on your skin could cause serious burns. c) Fill a second larger container with 50 milliliters (1.7 fl oz) of water. Pour in just enough water to cover the bottom of the second container. You??ll be using this container to nest your mixing container and prevent spillage or overflow, so make sure that itz big enough to hold your test materials comfortably. Ideally, your second container will also be slightly taller than your mixing container. If you??re using a 250 mL beaker as your mixing container, you might place it in a 1,000 mL beaker in order to leave a sufficient amount of space. Place your mixing container at the bottom of the larger container. Set the mixing container down gently in the shallow water. Check to make sure that at least 1⁄4 inch (0.64 cm) of water is still exposed around all sides of the mixing container. If itz not, find a larger container to fit it into. d) Add at least 32 grams (1.1 oz) of copper into the acid mixture. If possible, use laboratory-grade 99% pure copper pellets. Weigh the pellets on a precision scale in a lightweight container, making sure to weigh the container itself first and subtract its weight from the final reading. When you have a minimum of 32 grams (1.1 oz), dump the copper into your mixing container.[8] If you can??t find copper pellets for purchase, you can also use copper chips, shavings, wire, or even coins. Keep in mind, however, that the acid mixture will mostly dissolve the copper, so you won??t get it back. Copper is needed to kick start the oxidation reaction that will ultimately yield nitric acid. e) Cover the mixing container with a separate container and wait about 1 hour. The third container will trap the nitrogen dioxide generated as the copper dissolves in the acid mixture. The gas will then flow out of the mixing container and bubble up through the water in the holding container, producing nitric acid. A beaker thatz one or two sizes up should fit perfectly over your mixing container. You could also use a mason jar or other drinking container, provided itz made of glass. It may help to rest a small, heavy object, such as a book or piece of scrap wood, over the covering container to hold it down and keep it from bobbing as the escaping gas forces it upwards.
