Household bleach compare to household ammonia = D) Household ammonia has 10 times higher H + concentration.

Further explanation

pH is the acidity level of a solution that depends on the concentration of the H⁺ ion. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely related because they are associated with negative values.

A solution with a different value of n has a difference of H ion ion concentration of 10ⁿ.

See the attached picture

We can see the pH value of each solution:

Ammonia household pH = 11.5

Household bleach pH = 12.5

From the choices of answers we complete as follows:

A) Household bleach is more acidic than ammonia household.

B) Household bleach has 10 times higher H + concentration than household ammonia.

C) Household bleach has 100 times higher H + concentration than household ammonia.

D) Household ammonia has 10 times higher H + concentration.

E) Household ammonia has 100 times higher H + concentration.

Then both of them have H⁺ ion concentrations of

Ammonia household pH = 11.5

11.5 = - log H⁺

H⁺ = $10^{-11.5$

Household bleach pH = 12.5

12.5 = - log H⁺

H⁺ = $10^{-12.5$

The difference in concentration:

${\displaystyle {\frac{10^{-11.5}}{10^{-12.5}}=10$

Answer from: Quest

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence, the electronegativity (or the ability to attract electrons) is lessened."
