Nitric acid is an inorganic compound with the formula H N O 3. It is a highly corrosive mineral acid. [6] The compound is colorless, but samples tend to acquire a yellow cast over time due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water.

This calculator provides lab-ready directions describing how to prepare an acid or base solution of specified molarity (M) or normality (N) from a concentrated acid or base solution. To prepare a solution from a solid reagent, please use the Mass Molarity Calculator .

The table below gives the density (kg/L) and the corresponding concentration (% weight) of Nitric Acid (HNO 3) solutions in water at different temperatures in degrees centigrade (°C). The table was taken from "Perry's Chemical Engineers' Handbook" …

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. View More...

70% (w/w) Nitric acid means that 100 g of Nitric acid contains 70 g of HNO3. The density of 70% (w/w)Nitric acid is 1.413 g/ml at 25°C which means that the weight of the 1 ml of Nitric acid is 1.413 gram at 25°C. Molarity refers to the number of moles of the solute present in 1 …

A 70% (w/w) Nitric acid can be purchased from several commercial suppliers. It is a clear colorless liquid and can be diluted to prepare solutions of known concentrations. Here we describe a procedure to prepare a 1 M Nitric acid solution …

2018年5月17日 · The question 1: If concentrated nitric acid is a better oxidizing agent, then why does it oxidizes only 2 moles of Cu per 8 moles of nitric acid against the 3:8 ratio in dilute one? Answer: Conc. $\ce{HNO3}$ has more $\ce{NO3-}$ available to react.

Concentrated nitric acid burns may turn the skin yellow due to a reaction with proteins in the skin. Most commercially available concentrated nitric acid is 68-70%. Nitric acid at concentrations greater than 86% is considered to be fuming nitric acid, which is significantly more hazardous.

Concentrated nitric acid, often referred to as "concentrated" or "strong" nitric acid, is a solution of nitric acid in water with a high concentration of the acid. It typically contains around 68-70% nitric acid by weight and has a strong, pungent odor.
