Since citric acid is a weaker organic acid, it does not corrode iron rapidly. Overthecounter solutions of citric acid are generally offered at low concentrations, so they are more safe. Dipping a piece of rusty iron into the citric acid solution starts the reaction. The citric acid chelates the iron oxide, leaving a clean piece of iron and a
Gold acts like a sponge and absorbs nitric acid. This enables the nitric acid to clean the gold, such as gold nuggets or free gold taken from black sands. Most gold found in nature contains other metals, but some of these cannot be taken down in nitric acid (such as the platinum family). First The Dangers of Nitric Acid Place gold in a beaker or Pyrex container.

Physiochemical changes, including size, are known to affect gold nanoparticle cellular internalization and treatment efficacy. Here, we report the effect of four sizes of cystine/citric acidcoated confeitolike gold nanoparticles (confeitoAuNPs) (30, 60, 80 and 100 nm) on cellular uptake, intracellular localization and photothermal anticancer treatment efficiency in MDAMB231 breast cancer
CITRIC ACID 5KG FOOD GRADE. Used predominantly in cooking and manufacturing as a souring agent. Acid occurs naturally in many citric fruits such as lemons and limes. This sourness via fermentation is transferred into a white, crystallised powder similar to sugar. Citric acid powder is also used as a preservative agent. *ANHYDROUS CITRIC ACID

Citric acid is a weak organic acid that has the chemical formula C 6 H 8 O 7. It occurs naturally in citrus fruits. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms. More than a million tons of citric acid are manufactured every year.
Nature''s Touch Citric Acid Pickle is a mild pickling solution used for silver, gold, brass, and copper. Also a great cleaner for stainless steel shot. This biodegradable pickle is a safe yet very effective alternative to standard pickling solutions.
2. the citric acid acts as a chemical buffer. This means it will not make the Ph of your insides fluctuate wildly as the base (baking soda) hits the acid (stomach juice).
