What is one way to test whether an unknown solution is acidic or basic? a. test the solutions electrical conductivity b. check whether the solution has a slippery feel c. determine whether the solution has complete or partial dissolution d. observe whether the solution is clear or cloudy

Option (B) is the correct answer.

Explanation:

Bases are the substances which contain OH ions within the molecule.

For example, solution of NaOH is a basic solution as it contains OH or hydroxide group.

Bases change red litmus into blue and bases have a slippery and soapy texture.

Therefore, we can conclude that out of the given options, one way to test whether an unknown solution is acidic or basic is to check whether the solution has a slippery feel.
