<h3>What is the pH?</h3>
What we call the pH can be defined as the negative logarithm of the hydrogen ion concentration of the solution. We are aware that we can use the relation [H+] [OH-] = 1 * 10^-14 to handle the enormity of this problem.
Now, let us go about solving the problems;
1. pH = -log(1 x 10-7) = 7
2. [H+]= 1 * 10^-14/ 1 x 10^-3
pH = -log( 1 * 10^-11)
pH = 11
3. pH = -log( 1 x 10^-2)
pH = 2
4. pH = -log( 1 x 10^-10)
pH = 10
5. [H+]= 1 * 10^-14/ 1 x 10^-8
[H+]= 1 * 10^-6
pH = 6

An atom's mass is determined by its protons and neutrons.
An atom's charge is determined by its number of protons minus it number of electrons.
Atoms become cations, or positively charged when they lose an electron, and since electrons have a negative charge, they become anions, or negatively charged.
Water is a universal solvent.
Carbohydrates (carbs) are used by the body for energy.
Steroids and triglycerides are lipids.
Proteins that catalyze chemical reactions are called enzymes.
Answer:
Explanation:
Chlorine is the element of group 17 and third period. The atomic number of chlorine is 17 and the symbol of the element is Cl.
The electronic configuration of the element chlorine is:-
Chloride ion is formed when chlorine atom gain one more electron. So, the ground-state electron configuration for the chloride ion is:-
