Answer:
The drinks that the student should avoid - if he wants to avoid damage to his teeth - are drinks C and E, since they are acidic, according to their pH.
Explanation:
pH measures the acidity or alkalinity of a solution, taking into account the amount of hydrogen ions present in it, and established on a scale that goes from 0 to 14.
In chemistry, pH is derived from the formula that indicates:
<em>pH = - Log₁₀ αH⁺</em>
, where α is the activity of hydrogen ions.
A solution with a pH of 7 is considered neutral, above this value it is an acidic solution and below this value it is called acidic.
According to this:
- <em>Acidic drinks are: drink C (5.3) and E (2.4).</em>
- <em>The basic drinks are: drink A (11.9) and drink D (9.8).</em>
- <em>The neutral drink is the drink B (7), which corresponds to water.</em>

The two components of a solution are solvent and solute.
A solution is a homogenous mixture, stable, and the particles are very small.
Since it's Li+1, that means it's a Lithium ion, not just the element itself. The +1 charge means it loses an electron. The dot structure would be Lithium, and however many valence electrons it has minus 1
