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. Rate of onset: Immediate Persistence: Hours - days Odor threshold: ~1 ppm Source/use/other hazard: Used in many industries; Very corrosive to skin/mucous membranes as well as metals & other materials.

CAMEO Chemicals

Nitric acid is a nitrogen oxoacid of formula HNO3 in which the nitrogen atom is bonded to a hydroxy group and by equivalent bonds to the remaining two oxygen atoms. It has a role as a protic solvent and a reagent. It is a conjugate acid of a nitrate.

ChEBI

Nitric acid (HNO3). A colorless liquid that is used in the manufacture of inorganic and organic nitrates and nitro compounds for fertilizers, dye intermediates, explosives, and many different organic chemicals. Continued exposure to vapor may cause chronic bronchitis; chemical pneumonitis may occur. (From Merck Index, 11th ed)

Answer 2

Answer:

Explanation: N2O5+H20 - 2HNO3

1mole of N2O5 gives 2moles of

HNO3. Here 27 gm of N2O5 gives 27 gm of HNO3

No of moles of N2O5=27/108 = .25 moles

HNO3= 27/ 63= .42 moles

Theoretically no of moles of HNO3= 2× .25= .50 moles, wt = 50×63= 31.5gm

%yield = actual/ theoretical= 27/ 31.5 × 100 =85.7
