A solution has a [H+] = 0.00025. What is the pH of this solution?

Chemistry
1 answer:
Mamont248 [21]3 years ago
8 0

Answer: 3.60

Explanation:

pH is the negative logarithm of hydrogen ion concentration of a solution.

Mathematically, pH = -log(H+)

Since [H+] = 0.00025

Then, pH = - log (0.00025)

pH = - (-3.60)

pH = 3.6 (since the two minus signs will cancel out)

Thus, the pH of the solution is 3.6, making it an acidic solution

Based on the nature of the sub-atomic particles, the correct answers are:

5. No Charge

6. Negative

7. Neutrons and Protons

8. 35 electrons

9. atomic number is 5

10. atomic mass is 11

11. number of protons is 15

12. number of electrons is 20

13. number of neutrons is 30 (55 -25)

14. mass number is 7

15. number of neutrons is 11 (36 - 25)

<h3>What are the sub-atomic particles?</h3>

The sub-atomic particles are the electrons, protons, and neutrons.

The electron is negatively-charged, the proton is positively-charged, whereas, the neutron is neutral and has no charge.

The number of electrons in a neutral atom is equal to the number of protons.

The sum of protons and neutrons gives the mass number of the atom.

Considering the given questions:

5. What type of charge does a neutron have?

Answer = No Charge

6. What type of charge does an electron have?

Answer =  Negative

7. Which two subatomic particles are located in the nucleus of an

Answer = Neutrons and Protons

8. If an atom has 35 protons in the nucleus, how many electrons will it have orbiting the nucleus?

Answer = 35 electrons

9. What is the atomic number of the atom in the diagram above?

Answer = atomic number is 5

10. What is the atomic mass/mass number of the atom in the diagram above?

Answer = atomic mass is 11

11. How many protons are in the nucleus of an atom with an atomic number of 15?

Answer = number of protons is 15

12. How many electrons are in the nucleus of an atom with an atomic number of 20?

Answer = number of electrons is 20

13. How many neutrons are in the nucleus of an atom with an atomic number of 25?

Answer = number of neutrons is 30 (55 -25)

14. What is the mass number of an atom with 3 protons, 4 neutrons, and 3 electrons?

Answer = mass number is 7

15. How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25?

Answer = number of neutrons is 11 (36 - 25)

In conclusion, the mass number of an atom is the number of protons and neutrons in the nucleus of the an atom.

1. In the investigation of an unknown alcohol, there was a positive Jones test and a negative Lucas test. What deductions may be
pogonyaev

Answer:

1. When observing a positive test for the jones reagent and negative for the Lucas test, it indicates that it is in the presence of a primary alcohol.

Jones reagent behaves like a strong oxidant, where it transforms the primary alcohols into carboxylic acids and the secondary alcohols into ketones. Tertiary alcohols do not react.

With the Lucas test, tertiary alcohols react immediately producing turbidity, while secondary alcohols do so in five minutes. Primary alcohols do not react significantly with Lucas reagent at room temperature.

2. No reaction (See the attached drawing)

3. (see the attached drawing)

Enter an equation to show how h2po3− can act as a base with hs− acting as an acid. Express your answer as a chemical equation. I
vladimir2022 [97]

The acid - base equation between H2PO3^- and HS^- is H2PO3^- +  HS^- ⇄S^- + H3PO3.

<h3>What is an acid?</h3>

An acid is a substance that can donate hydrogen ions while a base is a substance that can accept hydrogen ion. This is the acid base definition according to Brownstead - Lowry.

To show the acid - base relationship between H2PO3^- and HS^-, we have the equation;

H2PO3^- +  HS^- ⇄S^- + H3PO3
