Answer:
The addition of hydronium ion increases the solubility of the salt
Explanation:
When a weak acid, MA dissociates in an aqueous solution, the following products in equilibrium are obtained;
MA ----> M+ + A-
The anion which is a conjugate base will be removed from the solution with the addition of a hydronium ion from an acid: 2H3O+ + 2A- ----> 2HA + 2H20
This distorts the reaction equilibrium. According to Le Chatelier’s principle, more MA will dissolve until in order to restore the previous equilibrium of the reaction.
Therefore, an acidic pH increases the solubility of almost all sparingly soluble salts whose anion is the conjugate base of a weak acid.
<span>nitrate. you can tell because the anion is NO3, which cancels out C and D. it's not A either, because nitrite is NO2. :D </span>
<span>Answer: option (b) atoms share electrons unequally.
That is because although the molecule or compound is neutral, some atoms will bear more electron density than others, so the atomes inside the compound that have more electron density will be partially negative while the atoms with less electron density will be partially positive.

Potassium (K) is an alkali metal, placed under sodium and over rubidium, and is the first element of period 4. It is one of the most reactive elements in the periodic table.
