taste sour
are gentle on skin and fabric
react with nonmetals
contain hydrogen
carry electrical charges

Answer 1

taste sour, contain hydrogen, carry electric charges

Step-by-step explanation:

Answer 2

Answer: Option 1, 4 and 5 describe acids accurately.

Step-by-step explanation:

Option 1: Acids have a sour taste because of the concentration of
`H^+` ion.

Option 2: They are corrosive in nature, that is they are not at all gentle with the skin and fabric as some acids intend to burn skin such as
`H_2SO_4` is a strong acid which can burn skin as well as fabric.

Option 3: Acids need electrons to release
`H^+` ions and non-metals do not donate electrons hence, there is no reaction between a non-metal and an acid.

Option 4: All acids do contain hydrogen. They dissociate in the presence of water to produce
`H^+` ions.

`HCl\overset{H_2O}{\rightarrow} H^++Cl^-`

Option 5: Acids do conduct electricity that is they carry electrical charges. This was explained by Arrhenius. He said that the acids dissociate into
`H^+`ions, when it is dissolved in water. These ions hence acts as charge carriers in water.
