A 10% nitric acid solution is commonly used as a cleaning product while sanitizing food and beverage processing equipment and also for metal surface treatment. A weak solution of nitric acid is also used by woodworkers to "pop" the grain of curly maple.
How do you make a 10 percent nitric acid solution?
3.1 Measure 10.6 ml of Nitric Acid LR and transfer into a 50.0 ml capacity beaker. 3.2 Pour about 75.0 ml of distilled water into a 250 ml capacity beaker. 3.3 Transfer slowly, through sidewalls of the beaker, 10.6 ml of Nitric Acid LR into above said beaker, while gentle mixing, by using a glass rod.
What is nitric acid used for at home?
Nitric acid is used in the production of ammonium nitrate for fertilizers, making plastics, and in the manufacture of dyes. It is also used for making explosives such as nitroglycerin and TNT. When it is combined with hydrochloric acid, an element called aqua regia is formed.
What does 70% nitric acid mean?
Using 70% concentrated nitric acid as an example: 70% nitric acid means that 100 grams of this acid contains 70 grams of HNO3. The concentration is expressed at 70% wt./wt. or 70 wt. % HNO3.
What is nitric acid usually used for?
Nitric acid is used for the production of ammonium nitrate, a major component of fertilizers. It is also used for producing explosives like nitroglycerin and trinitrotoluene (TNT) and for oxidizing metals.
What does nitric acid do to humans?
Exposure to nitric acid can cause irritation to the eyes, skin, and mucous membrane; it can also cause delayed pulmonary edema, pneumonitis, bronchitis, and dental erosion. Nitric acid is highly corrosive. Workers may be harmed from exposure to nitric acid.
What does nitric acid do to pennies?
A few drops of nitric acid are placed on an older copper penny (and the reaction is shown). Discussion: The reaction produces red-brown nitrogen dioxide gas and a hot, concentrated solution of copper(II) nitrate, which is blue. As the water evaporates and the solution cools, crystals of Cu(NO3)2(s) begin to form.
