QUESTION:

Define each of the following terms:
i. Solubility
ii. Saturated solutions
iii. Ions
iv. Isotopes

ANSWER:

i. Solubility
The Solubility of a solute in a solvent at a particular temperature is the maximum amount of the solute in grams or moles that will saturate 1dm3 of the solvent at that temperature.

ii. Saturated Solution
Saturated solution of a solute at a partivular temperature is one which contains as much solute as it can dissolve at that temperature in the presence of undissolved solute particles.

iii. Ion
This is any atom or group of atoms which possess an electric charge. The types of ion include:

Cation
Positively charged element e.g Na+, K+,
Anion
Negatively charged elements e.g Cl-, Br-

iv. Isotopes
These are atoms of an element that possess the same Atomic Number (Proton Number) but different Mass Number (Atomic Mass). Note that difference in Mass Number is due to differences in Neutron number.
Elements which undergo isotopy are: Hydrogen, Oxygen, Carbon, Chlorine.

Note: Kindly reach out on any questions
