Introduction to general chemistry including basic concepts about matter, atomic structure, chemical bonds, gases, liquid, and solids, solutions, chemical reactions, acid, bases, and salt;
organic and biochemistry including hydrocarbons and their derivatives, carbohydrates, lipids, proteins, enzymes, vitamins, and minerals, nucleic acids; principles of physics and applications to nursing including gravity and mechanics, pressure, heat and electricity; nuclear chemistry and nuclear physics, effects of radiation on human beings, and protection and disposal. The aim of the course is to acquire knowledge and skills in general biological science, general chemistry and physics.
Characteristics of a Solution
A chemical solution exhibits several properties:
- A solution consists of a homogeneous mixture
- A solution is composed of one phase (e.g., solid, liquid, gas).
- Particles in a solution are not visible to the naked eye.
- A solution does not scatter a light beam
- Components of a solution cannot be separated using simple mechanical filtration.
Definition of Solubility:
Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solvent.
or
Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.
Definition of Saturated Solutions
A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. The additional solute will not dissolve in a saturated solution.
or
The term saturated solution is used in chemistry to define a solution in which no more solute can be dissolved in the solvent. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas.
