Household ammonia has a pH of 12; household bleach has a pH of 13. Which of the following statements about these substances is true? Group of answer choices The ammonia has 10 times as many OH- ions as the bleach. The ammonia has 10 times as many H+ ions as the bleach. A solution that could buffer the bleach and ammonia would remove excess OH- ions. Both of these substances are strong acids.

The ammonia has 10 times as many H+ ions as the bleach.

Explanation:

pH is defined as -log[H+]

[H+] of ammonia is = 10^-12 = 1x10-12M

Bleach = 1x10-13M

pOH = 14-pH = 2 for ammonia and 1 for bleach

[OH-] = 10^-pOH = 0.01M for ammonia and 0.1M for bleach

Thus:

The ammonia has 10 times as many OH- ions as the bleach. FALSE.

The ammonia has 10 times as many H+ ions as the bleach. TRUE.

A solution that could buffer the bleach and ammonia would remove excess OH- ions. FALSE. A buffer maintains OH- ion concentration

Both of these substances are strong acids. FALSE. Strong acids have pHs < 7

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
