WebNitric acid is the inorganic compound with the formula H N O 3. It is a highly corrosive mineral acid. [6] The compound is colorless, but older samples tend to be yellow cast due to decomposition into oxides of nitrogen. Most commercially available nitric acid has a concentration of 68% in water.
Nitric acid is normally considered to be a strong acid at ambient temperatures. There is some disagreement over the value of the acid dissociation constant, though the pKa value is usually reported as less than −1. This means that the nitric acid in diluted solution is fully dissociated except in extremely acidic solutions. The pKa value rises to 1 at a temperature of 250 °C. Nitric acid can act as a base with respect to an acid such as sulfuric acid: mondstat specialties genshinWebĐáp án: Cho 5,6g Fe tác dụng với dung dịch HNO3 1M vừa đủ thì thu được V lít khí NO a tính V? b tính nồng độ mol dung dịch HNO3 đã dùng?
