Ammonium hydroxide is considered a weak base because it produces few hydroxide ions in aqueous solution. (Option a)
<h3>Strength of electrolytes</h3>
- Strong electrolytes: are completely ionized in aqueous solution.
- Weak electrolytes: are partially ionized in aqueous solution.
Let's consider the ionization of ammonium hydroxide, which is a weak base.
NH₄OH ⇄ NH₄⁺ + OH⁻
Why is it considered a weak base?
a. it produces few hydroxide ions in aqueous solution. Yes, since it dissociates partially.
b. it produces few hydrogen ions in aqueous solution. No, since it does not produce hydrogen ions.
c. it does not conduct electricity in aqueous solution. No, since it conducts electricity, although poorly.
d. it will not take part in a neutralization reaction. No, since it will be neutralized by acids.

The chemical formula of manganese (Il) phosphate is Mn3(PO4)2, which is option 2.
<h3>What is chemical formula?</h3>
The chemical formula of a compound is the notation indicating the number of atoms of each element present in a compound.
The chemical formula of a compound tells us the type of elements in the compound, the number atoms of each element in the compound and in what proportion these elements are present.
According to this question, manganese II phosphate has the chemical formula of Mn3(PO4)2.
This chemical formula shows that it posseses the following:
- 3 manganese atoms
- 2 phosphorus atoms
- 8 oxygen atoms

Dalton’s law states that any given time the percentage of each of these (toxic?) gasses in the air we breathe it’s contribution.
People who ascend high altitudes experience Delton’s law when they try to breathe. Oxygen’s pressure decreases a total atmospheric pressure decreases in accordance with Dalton’s law.
