What are facts about nitric acid?

Answer 1

They do not melt substances. They disolve (break down) almost every substance they come in contact with. Mixing acids and bases cause a neat reaction

1. Acids can be nuetralised by adding alkali too it. But it must be the same amount of alkali as there is acid.
2. Acids have a pH scale lower than 7
3. Acids (on the pH scale) are reds and Oranges
4. Some acids are vinegar, lemon, lemon juice, oranges, Orange Juice, bleach ...and loads more...
5. Acids turn litmus paper red.

When it touches a surface it starts to fizz up
1- acids give H+ ions in aqueous solution, 2- they are polar covalent compounds, 3 they have sure taste, 4-they produce salt with a base, 5-they decompose the carbonates and bicarbonates, 6-they turn the blue litmus red, 7- they evolve hydrogen when react with metals which are above hydrogen in reactivity series, 8- they are good electrolytes, 9- their pH values are less than 7, 10- they may be kept in plastic container but not in metallic.
1)Acids have tendency to donate protons or electrons.

2)They have a pH value of less than 7.

3)They turn litmus paper to red.

4)If it is highly concentrated,they can dissolve metals.

5)Aquaregia(3:1 ratio of nitric acid and hydrochloric acid)can dissolve metals such as silver,gold...etc.

6)Carborane super acid,Hypochloric acid,Magic acid are some of the examples of strongest acids.

7)Acids react with bases.

8)Some acids are present in our daily food such as citric acid in lemons,Tartaric acid in Tamarind,Lactic acid in curd..etc.

9)Some animals release acids.For example,when an ant bites,we feel a burning sensation.This is due to the release of formic acid by ants.

10)Different acids have different strengths.Strength of acids is completely different from corrosion due to that particular acids.

Answer 2

Nitric acid is a strong mineral acid with formula HNO3. It is commonly used in the production of fertilizers, explosives, and used as a cleaning agent. Nitric acid is highly corrosive and can cause severe burns if it comes into contact with skin.

Answer 3

It can not melt gold.
