The pH of a solution is 1. Which of the following statements are also true for the solution? (Select all that apply.)

It will change the color of red litmus to blue.
The concentration of hydronium ion is equal to the concentration of hydroxide ion.
The solution is acidic.
It will change the color of blue litmus to red.
The solution is basic.
The concentration of hydroxide ion is more than the concentration of hydronium ion.
It will not change the color of Phenolphthalein.
It will turn Phenolphthalein pink.
The concentration of hydronium ion is higher than the concentration of hydroxide ion.

It will change the color of red litmus to blue .No.

The concentration of hydronium ion is equal to the concentration of hydroxide ion. It is greater than OH
The solution is acidic.yes
It will change the color of blue litmus to red. yes
The solution is basic. no
The concentration of hydroxide ion is more than the concentration of hydronium ion.no
It will not change the color of Phenolphthalein.Doesn't that depend upon what color the phenolphthalein is initially?
It will turn Phenolphthalein pink.no
The concentration of hydronium ion is higher than the concentration of hydroxide ion. yes

The following statements are true for a solution with a pH of 1:

- The solution is acidic.
- It will change the color of blue litmus to red.
- It will not change the color of Phenolphthalein.
- It will turn Phenolphthalein pink.
- The concentration of hydronium ion is higher than the concentration of hydroxide ion.

So, the correct statements are:

- The solution is acidic.
- It will change the color of blue litmus to red.
- It will not change the color of Phenolphthalein.
- It will turn Phenolphthalein pink.
- The concentration of hydronium ion is higher than the concentration of hydroxide ion.

To determine which statements are true for a solution with a pH of 1, we need to understand the properties of pH and how it relates to acidity or alkalinity.

The pH scale ranges from 0 to 14, with values below 7 considered acidic, values of 7 considered neutral, and values above 7 considered basic or alkaline.

Now, let's evaluate each statement:

1. It will change the color of red litmus to blue. - False
Red litmus turns blue in the presence of a base, not an acid. Since the solution has a pH of 1 (an acidic value), it will not change the color of red litmus.

2. The concentration of hydronium ion is equal to the concentration of hydroxide ion. - False
In an acidic solution, the concentration of hydronium ions (H3O+) is higher than the concentration of hydroxide ions (OH-). This statement is only true for neutral solutions where pH equals 7.

3. The solution is acidic. - True
Since the pH of the solution is 1, it falls into the acidic range. Therefore, this statement is true.

4. It will change the color of blue litmus to red. - True
Blue litmus paper turns red in the presence of an acid. As the solution has a pH of 1 (an acidic value), it will change the color of blue litmus to red.

5. The solution is basic. - False
As mentioned earlier, a pH of 1 indicates an acidic solution, not a basic one.

6. The concentration of hydroxide ion is more than the concentration of hydronium ion. - False
In an acidic solution, the concentration of hydronium ions (H3O+) is higher than the concentration of hydroxide ions (OH-). This statement is only true for basic solutions.

7. It will not change the color of Phenolphthalein. - True
Phenolphthalein is a pH indicator that turns pink in a basic solution and remains colorless in acidic solutions. Since the solution has a pH of 1 (acidic), it will not change the color of Phenolphthalein.

8. It will turn Phenolphthalein pink. - False
As mentioned earlier, Phenolphthalein turns pink in the presence of a base, not an acid. Therefore, this statement is false for a solution with a pH of 1.

9. The concentration of hydronium ion is higher than the concentration of hydroxide ion. - True
In an acidic solution, the concentration of hydronium ions (H3O+) is higher than the concentration of hydroxide ions (OH-). So, this statement is true.

Based on the explanations provided, the statements that are true for a solution with a pH of 1 are:

- The solution is acidic.
- It will change the color of blue litmus to red.
- It will not change the color of Phenolphthalein.
- The concentration of hydronium ion is higher than the concentration of hydroxide ion.
