PROPERTIES OF SOLUTIONS A solution is a mixture of materials‚ one of which is usually a fluid. A fluid is a material that flows‚ such as a liquid or a gas. The fluid of a solution is usually the solvent. The material other than the solvent is the solute. We say that we dissolve the solute into the solvent. Some solutions are so common to us that we give them a unique name. A solution of water and sugar is called syrup. A solution of sodium chloride (common table salt) in water is called brine

I. Introduction A buffer system is a mixture of a weak acid or a weak base and its salt (conjugate base or conjugate acid‚ respectively) that permits solutions to resist large changes in pH upon the addition of small amounts of hydrogen ions (H+) or hydroxide ions (OH-). If the same amount of the buffer is added‚ the pH may only change a fraction of a unit. Our blood is a good example of a buffered system. It is maintained under a pH of 7.4. Thus‚ buffers are important in many areas of chemistry

The relative contributions of nature and nurture are an apparent part of human development which makes us ask the question‚ are heredity and environment opposing forces? The question of nature vs. nurture can be examined and can be attempted to be comprehended in many ways.
