If an atom gains an electron and gets a negative charge because of it, it is a negatively charge ion AKA an anion.
Answer:
a. decrease the amount of the common ion in the system
Explanation:
The correct option is - a. decrease the amount of the common ion in the system
Reason -
Adding a common ion decreases solubility, as the reaction shifts toward the left to relieve the stress of the excess product.
Adding a common ion to a dissociation reaction causes the equilibrium to shift left, toward the reactants, causing precipitation.

I have no skins for you my brother and my girlfriend and my uncle are going out and have you come on the house for me to do you have to get on your phone
Answer:
a and b are correct
Explanation:
This because both are aqueous solutions,therefore, identity of solvent is same that is water.
And because both solutions are non electrolyte they would not ionize in solution, and for the same concentration, the freezing point of both solution would also be same. Since depression in freezing point is a colligative property this means that it depends on number of solute particles not nature of particles
.
Hence answer is that their freezing points and Identity of the solvent shall remain the same.
