Abstract Water “hardness” was analyzed in this experiment‚ through the determination of CaCO3 concentration. This was achieved by the titration of an unknown solution using a standardized 0.1M EDTA‚ and addition of Eriochrome Black T to the unknown‚ to indicate the endpoint of the titration. The average concentration of CaCO3 obtained was 1034 ppm‚ with a standard deviation of 2.4495. The results indicate that the unknown solution can be considered as hard water. Introduction The

Standard Temperature and Pressure‚ or STP. The purpose of this experiment is to derive the universal gas constant for gases experimentally by collecting gases from the neutralization reaction and determining the volume and pressure of the gas and then the partial pressure of the gas formed. The single displacement reaction between magnesium metal and hydrochloric acid will be used to generate the hydrogen gas: Mg (s) + 2 HCl (aq) MgCl2 (aq) + H2 (g) Experimental Method In preparing the

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its
