Introduction

This article discusses the classification of alcoholism and investigation of personality traits. As the subjects were selected 100 men with excessive alcohol consumption. They were interviewed by telephone or visual conversation. Thereafter, they were designed to a research center for examination. And as a result, the hypothesis that male individuals with excessive alcohol consumption do not have a specific ‘‘addictive’’ personality, was confirmed in this study.

Body

Authors tried to answer the question about do male individuals with excessive alcohol consumption have a specific “addictive” personality or not? The main ...

A When water is added to lead chloride, the solute sparingly dissolves with some undisclosed particles settling at the bottom of the beaker. Lead chloride is only sparingly soluble in water. When the dilute hydrochloric acid is added to the saturated solution of lead chloride, a white precipitate is formed. This is because of the common ion effect where the excess chloride ions from HCL cause lead chloride to precipitate. Pb2+ aq + 2Cl-aq PbCl2 s B 0.1M lead nitrate +0.1M sodium oxalate

Introduction

During the Solubility Product experiment you calculated the Solubility Product, Ksp, for calcium hydroxide, an ionic solid that is sparingly soluble in water. This was achieved by titrating a saturated solution of Ca(OH)2 prepared at a certain temperature. The saturated, aqueous, solution of Ca(OH)2 is represented in equation form as shown below.

The equilibrium expression for calcium hydroxide is shown below.

Ksp = [Ca2+][OH–]2 Eq. 1 Equilibrium constants are temperature-dependent and the value of an equilibrium constant can be related to temperature and the Gibbs Free Energy, Gº, through the equation: ∆G°=-RTlnK Eq. 2 In this case we can substitute our ...
