A student is given two beakers. The first contains a 2M solution of an acid. The second a 2M solution of a base.
A) Which has the lowest pH?
B) Which has the highest hydronium concentration?
C) In which is the water acting as a base?

The answer to your question is below.

Explanation:

a) pH is a scale to measure the acidity or basicity of a solution. It goes from 0 to 14. Acid solutions have a lower pH than basic solutions.

Then, the 2 M acid solution has a lower pH

b) Hydronium ions are represented by [H₃O⁺]  and are characteristic of acids. So the concentration is higher in the solution 2 M of an acid.

c) Also, the answer is the 2 M solution of an acid.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
