An unknown liquid has a pH lower than 7, conducts electricity poorly, and tastes sour, what kind of solution is the unknown?

Weak Acid solution

Explanation:

Acidic substances usually have a pH of 0.1-6.9 or it is usually less than 7. Acidic substances too have a very unique sour taste.

However it is understood that it conducts electricity poorly which means the acid doesn't readily dissociate in water. This makes it a weak acid and an example is Acetic acid.
