What metal will not dissolve in nitric acid?
What metals does nitric acid not dissolve? Some precious metals, such as pure gold and platinum-group metals do not react with nitric acid, though pure gold does react with aqua regia, a mixture of concentrated nitric acid and hydrochloric acid.
What is the normality of concentrated nitric acid?
The ACS defines two grades of reagent acid: nitric acid, having a concentration of 69.0-71.0 wt% HNO3, and nitric acid, 90%, having a concentration of 90 wt% HNO3. Both have maximum allowable levels of chlorides, sulfates, arsenic , heavy metals, iron , and residue after burning.
Is nitric acid the same as sulfuric acid?
Sulfuric acid is more dangerous acid than nitric acid. Sulfuric acid has two full positive charges on sulfur. This has the effect of pulling electrons from the attached oxygen atoms which increases the apparent electronegativity of the oxygen atoms.
Does nitric acid burn the skin?
Yes it burns. Nitric acid, depending on the concentration, can produce severe burns and discolor your skin. We use nitric acid as a preservative for certain water samples and I recently got some on my hand. My finger started tingling and felt numb.
What is the molarity of 65% nitric acid?
The molarity of a solution of 65.05 % m/m nitric acid is 14.00 M.
What is the molarity of 68 nitric acid?
68% of Nitric acid by mass in aqueous solution means that 68g [[68 × 100]/100] of Nitric acid present in 100g of solution. Therefore the molarity of the sample is 16.24 M.
How do you find the molarity of nitric acid?
3:194:47Calculate the molality and molarity of concentrated nitric acid - YouTubeYouTubeStart of suggested clipEnd of suggested clipAnd again that's mole Oh mo l8l. Now we need to calculate the molarity we already have the moles ofMoreAnd again that's mole Oh mo l8l. Now we need to calculate the molarity we already have the moles of solute. But here we're given 100 grams of solution. So we need to convert grams of solution to
How do you calculate molarity of an acid?
Molarity is a ratio between moles of solute and volume of solution. By dividing the number of moles of HCl by the volume (L) of solution in which it was dissolved, we will obtain the molarity of the acid solution.

What is the molar concentration of nitric acid?
Dividing the grams of HNO3 by the molecular weight of HNO3 (63.01 g/mole) gives the number of moles of HNO3 / L or Molarity, which is 15.7 M.
How do I calculate molarity?
As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.
What is the molarity of 37% HCl?
12 molarThus, fuming/concentrated HCl 37% is 12 molar (= M = mol/L).
How do I calculate molar concentration?
Concentration formula: To find the molar concentration of a solution, simply divide the total moles of solute by the total volume of the solution in liters.
How do you convert concentration to molarity?
Interchanging Between Percent Concentration and MolarityExample:X = 0.85 x 1000 /100.X = 8.50 g/L.Molarity = g of solute/GMW of solute x 1 liter.X = 8.5 g/GMW x 1.0.X = 8.5/58.44.Molarity = 0.14M.
What is the average concentration of nitric acid in a cigarette?
Nitric acid is present in the gas-phase of environmental cigarette smoke; the average concentration range was reported as 24 to 380 umol/mol CO , generated using one to four cigarette (1R1 Kentucky Reference cigarette) electrically lit and burned in a 30 cu cm Teflon chamber (1).
How is nitric acid made?
Almost all commercial quantities of nitric acid are manufactured by the oxidation of ammonia with air to form nitrogen oxides that are absorbed in water to form nitric acid. Because nitric acid has a maximum boiling azeotrope at 69 wt%, the processes are usually categorized as either weak (subazeotropic) or direct strong (superazeotropic). Typically, weak processes make 50-65 wt% acid and direct strong processes make up to 99 wt% acid. Strong acid may also be made indirectly from the weak acid by using extractive distillation with a dehydrating agent. Nitric acid concentration processes use a dehydrating agent such as sulfuric acid or magnesium nitrate to enhance the volatility of HNO3 so that distillation methods can surpass the azeotropic concentration of nitric acid.
What is the most common use of nitric acid?
Hazardous Substances Data Bank (HSDB) The largest use of nitric acid (about 74 to 78% of total US production) is for the manufacture of ammonium nitrate. ... The next three largest uses for nitric acid are in the manufacture of cyclohexanone (about 8 to 9%), dinitrotoluene (about 4%), and nitrobenzene (about 3 to 4%).
What minerals neutralize nitrates?
Nitric acid will be gradually neutralized by hardness minerals ( calcium and magnesium) in water. The nitrate ion may persist longer but will ultimately be consumed as a plant nutrient.
What is the most favorable course of action for a chemical?
SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.
How to treat a chemical in the eye?
Eye: If this chemical contacts the eyes, immediately wash the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Contact lenses should not be worn when working with this chemical. Skin: If this chemical contacts the skin, immediately flush the contaminated skin with water. If this chemical penetrates the clothing, immediately remove the clothing and flush the skin with water. Get medical attention promptly. Breathing: If a person breathes large amounts of this chemical, move the exposed person to fresh air at once. If breathing has stopped, perform mouth-to-mouth resuscitation. Keep the affected person warm and at rest. Get medical attention as soon as possible. Swallow: If this chemical has been swallowed, get medical attention immediately. (NIOSH, 2016)
Is nitric acid toxic?
Nitric acid, red fuming appears as a pale yellow to reddish brown liquid generating red-brown fumes and having a suffocating odor. Very toxic by inhalation. Corrosive to metals or tissue. Prolonged exposure to low concentrations or short term exposure to high concentrations may result in adverse health effects.
