labs. For this particular lab we will utilize our scientific knowledge of related to gravimetric procedures to find the chloride content in an unknown soluble salt. Theory: Using our developed knowledge of the conservation of mass‚ solubility and precipitation it is possible (with some degree of error) to know the content of chlorine in a particular salt by dissolving it in water‚ than extracting it through precipitation. This method is based on quantitative isolation of pure chlorine on both sides

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

or the number of steps between the reactant and product. In this experiment‚ you will measure and compare the quantity of heat involved in three reactions. These heats of reaction will be measured using a styrofoam calorimeter. The three reaction are shown below. Reaction 1: The dissolving of solid sodium hydroxide in water. NaOH(s) ---> Na+(aq) + OH-(aq) + heat Reaction 2: The reaction of solid sodium hydroxide with dilute hydrochloric acid. NaOH(s)

Abstract. This report is about how to standardize a Sodium Hydroxide (NaOH) solution by titrating it with pure sample of Potassium acid Phthalate (KHC8H4O4). This experiment has two sections. The first section is to standardize the Sodium Hydroxide by titration. Three sample of 0.7 – 0.9 g of solid KHP are place into each of the three numbered Erlenmeyer flasks. 50 ml of distilled water are added to each three of it from graduated cylinder and constantly shake it until the KHP solution are completely

UTAR FHSC1134 Inorganic Chemistry Trimester 3 Experiment 1 ________________________________________________________________________ Title: Investigating the Properties of Period 3 Oxides Aim: To examine the oxides of Period 3 elements and describe their structure and bonding. Introduction: Generally‚ there are oxides of metals and non-metals. Metals burn in oxygen to form basic oxides while non-metals form acidic oxides. Structurally‚ they are covalent or ionic compounds. You are to

The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis
