Answer:
A strong acid
Explanation:
PH is a scale that measures the acidity or nativity of any substance being tested. PH is mostly usually carried out in aqueous solutions also.
The scale is from 1 - 14, with 7 being neutral. A solution with a PH of 7 is said to be chemically neutral. On the other hand, a solution with a PH of 2 is tagged as a strong acid. This is so, because on the scale, the more closer you move to 1, the acidity of such solution increases and the more you move to 14, it's basicity reduces. And as such, only solutions with a PH value of 1 are stronger than that of 2.
Example of a solution with a PH of 2 is a lemon juice.
Is there a multiple choice?
