One day (24 hours), because one rotation of earth on its axis is the position of the countries to the sun shifting, thus resulting in the periods of sun and moon, (the day and the night).

The correct answer is option C. Solutions that have more OH– than H+ ions are bases. These are substances that are slippery to touch and has an astringent taste. It reacts with acids in a neutralization reaction forming salts. It accepts protons. Examples are sodium hydroxide and potassium hydroxide.
To determine the pOH Of solution we can use the pka value for the ionization constant of water at 25 degrees Celsius to solve this the relationship would be as follows.
PH + POH = 14
3.9 + x = 14
POH = 14 - 3.9 = 11 - 0.9 = 10.1
The POH would be 10.1.
