Acid-Base Calculations The Ion-Product Constant for Water‚ Kw Water undergoes ionization to a small extent: H20(l) H+(aq) + OH–(aq) The equilibrium constant for the reaction is the ion-product constant for water Kw: (1) This is a key equation in acid-base chemistry. Note that the product of [H+] and [OH–] is a constant at a given temperature (Eq(1) value is for 25oC). Thus as the hydrogen ion concentration of a solution increases‚ the hydroxide ion concentration decreases

Knowledge is power. This statement is very true but also cliché. African Americans firmly believed that literacy was the implement and symbol of liberation and equality‚ in white societies. Education is what makes you “free”. When a child learns to talk‚ read‚ and write‚ the child has more power and respect then one of a new born. The child can now tell you “yes” or “no” based on situation after an evaluation. As Malcolm X famously said “education is the passport to the future‚ for tomorrow belongs

Acid-Base Titrations A Titration of Potassium Hydroxide Phthalate and Sodium Hydroxide Hanna Piper Department of Chemistry‚ SUNY College at Brockport‚ Brockport‚ NY 14420 Chemistry 205.06 Abstract Titrations are used to find the molarity of an unknown solution. A titration begins with an analyte and titrant being used to measure the unknown molarity of the analyte. In the following experiment‚ sodium hydroxide was used as the titrant and potassium hydroxide phthalate was used as the

* Knowledge Retention Strategies in Industries * A brief introduction Knowledge management is the systematic process of finding‚ selecting‚ organizing‚ distilling and presenting information. Tacit knowledge is the knowledge we each carry in our heads about how to do things‚ who to call and the lessons learned through experience. Making it explicit is recording in some media that allows another person to use it. The media can be a complex computer database or a piece of paper tacked

Validity of Knowledge This paper will explain the validity of John Locke’s Theory of Knowledge. Epistemology has been the topic of discussion for many philosophers over the centuries. The study of knowledge is important because as humans‚ it is necessary to understand where the basis for our knowledge originates. Locke‚ like many philosophers believed that all knowledge about the world is derived from sensory perceptions. Empiricists such as Locke believe this “posteriori” view of knowledge. He explains
