Question

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?

Answer 1

The answer to your question is below.

Step-by-step 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.
