Chemical properties of an acid corrosive, increases the concentration of hydrogen ions when added to water, forms hydrogen gas when it comes in contact with a metal, and forms salt and water when added to a base. corrosive, tastes sour, forms hydrogen gas when it comes in contact with a metal, and feels sticky to the touch. corrosive, increases the concentration of hydrogen ions when added to water, reacts with metals to form hydrogen, and tastes sour. taste sour, increases the concentration of hydrogen ions when added to water, frequently burn nose when smelt, and forms salt and water when added to a base.

This is a list of well known characteristics of acids:

1) acids increase the concentration of hydronum ions ([H3O+]) when dissolved in water

2) acids taste sour

3) many are corrosive (the higher the acidity the higher the corrosive property)

4) when acids react with some metals produce hydrogen gas

5) acids conduct electricity (due to the presence of hydronium ions)

6) acids neutralize bases

7) acids combine with bases to produce water and salt

8) acids lower the pH of solutions.

They do not feel sticky to the touch. Bases fell slippery but there is not that property of sticky sensation about acids, although some highly concentrated strong acids have high viscosity. You cannot touch highly concentrated strong acids.
