    equivalence point is known then chemist can correctly determine the amount the concentration of the acid and the base. In this experiment acid-base titration will be used to determine the concentration of HCl at equilibrium when it reacts with the NaOH H+ (aq)+ Cl- (aq) + Na+ (aq) + OH- →H2O(l) + Na+ (aq)+ Cl- (aq) Procedure When performing this experiment one must first obtain and wear goggles. Next add 40mL of distilled water to a 100mL beaker‚ then add 5.00mL of HCl to the beaker

    EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

    Objective The purpose of this experiment is to identify an unknown proprietary drug using thin-layer chromatography. The unknown’s behavior in thin-layer chromatography will be compared with that of its possible component analgesics. The possible unknowns and their analgesic ingredients will be Anacin (aspirin‚ caffeine)‚ Excedrin (acetaminophen‚ caffeine‚ aspirin)‚ Motrin (ibuprofen)‚ and Tylenol (acetaminophen). Introduction Thin-layer Chromatography(TLC) was the method used to figure out and

    Heart Rate Of Daphnia. Aim: In this investigation I am going to see how alcohol affects the heart. Due to the ethical and safety issues involved in using in an investigation such as this I am going to use Daphnia (water flea) to conduct this experiment. Although humans and Daphnia are very different organisms‚ the affect that alcohol has upon the heart should be similar. Hypothesis: The hypothesis I am going to test during the investigation is: ‘Increasing the percentage of concentration

    Gas Chromatography: Purifying alcohol Introduction The goal of this lab is to understand the principles of chromatography by purifying alcohol using fractional distillation. Running standards with gas chromatography we were able to see and calibrate our data to find not only how much ethanol our alcohol attained but also what a mixed unknown sample contained. Chromatography is a way of being able to separate substances in solution that can help not only identify the analytes (the studied
