Question

Identify the substance that each property describes. only acid only base both acid and base feels slippery arrowright tastes sour arrowright conducts electricity arrowright

Answer 1

1.  Only Acid -> Taste sour

(There is increase in H+ ion concentration, providing more ions to tongue and giving sour taste)

2. Only Base -> Feels slippery

Bases dissolve fatty acids and oil from the skin, as a result of which there is a decrease in friction so feels slippery.

3. Both Acid and Base

Presence of H+ in acids and OH- ions in bases makes it conducting in aqueous solution.

Any hydrogen-containing material that has the ability to give another substance a proton is considered an acid. Any molecule or ion that can accept a hydrogen ion from an acid is known as a base.
