What is the hydronium ion concentration in a solution of hcl that has a ph of 4.65? × 10n m n = what is the hydroxide ion concentration in a solution of nh3 with a poh of 4.65? × 10n m n =

Explanation:

Hydronium ions concentration of the solution with pH value of 4.65.

Hydroxide ions concentration of the solution with pOH value of 4.65.

The hydrogen ions concentration of the solution of HCl that has a pH of 4.65 is 2.23 × 10-5, and the hydroxide ion concentration of a solution of NH3 with a pOH of 4.65 is 2.23 × 10-5 M

pH of a solution is defined as the negative logarithm to the base 10 of the hydrogen ion concentration of the solution.

pH of solution = 4.65

[H+] = antilog -4.65

[H+] = 2.23 × 10-5 M

pOH of a solution is defined as the negative logarithm to the base 10 of the hydroxide ion concentration of the solution.

pOH of solution = 4.65

[OH-] = antilog -4.65

[OH-] = 2.23 × 10-5 M

Therefore, the hydrogen ions concentration of the solution of HCl that has a pH of 4.65 is 2.23 × 10-5, and the hydroxide ion concentration of a solution of NH3 with a pOH of 4.65 is 2.23 × 10-5 M

58750.08068 is the answer i think

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
