Question

2. As the pH approaches 0, what happens to the concentration of OH- ions
3. As a solution becomes more acidic, how does it affect the concentration of H3O+ and OH- ions?
4. As the pH approaches 14, what happens to the concentration of H3O+ ions?
5. As the pH approaches 14, what happens to the concentration of OH- ions?
6. As a solution becomes more basic or alkaline, how does it affect the concentration of H3O+ and OH- ions?

Answer 1

Answer:

Explanation:

2. WHEN THE  pH REACHES 0 THEN  THE OH- CONCENTRATION WILL BE VERY LOW

3. AS THE SOLUTION BECOMES MORE ACIDIC THEN THE CONCENTRATION OF H3O+ IONS WILL INCREASE AND OH- IONS WILL REDUCE DRASTICALLY

4. IT WILL DECREASE

5. IT WILL INCREASE

6.

Answer 2

As the pH approaches 0, there are a lesser concentration of OH- ions

As a solution becomes more acidic, it means it is less than the pH scale of 7, and the concentration of H3O+ increases while OH- decreases.

What is the autoionization of water?

The autoionization of water means the chemical reaction process by which water molecules generate the hydronium ion (H₃O⁺) and the hydroxide ion (OH⁻).

However, H⁺ and H₃O⁺ are frequently used simultaneously to describe the hydrated proton, also known as the hydronium ion.

On a pH scale, the solution greater than 7 is basic while less than 7 is acidic

Using the criteria of pH scale;

• If pH is greater than 7, there is higher OH⁻ than H⁺
• If pH is less than 7, there is higher H⁺ than OH⁻

From the given information:

• As the pH approaches 0, there are a lesser concentration of OH- ions
• As a solution becomes more acidic, it means it is less than the pH scale of 7, and the concentration of H3O+ increases while OH- decreases.
• As pH approaches 14, the concentration of H3O+ reduces.
• As pH approaches 14, the concentration of OH-  increases.
• As the solution becomes more basic, the pH is greater than 7, thus the concentration of H3O+ decreases, and the OH- increases.
