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

Collecting Butane Gas The purpose of the lab was to determine the molecular mass of Butane‚ and this was done by using the ideal gas law (PV=nRT). The materials used were: match‚ funnel‚ bucket‚ cylinder‚ thermometer‚ lighter‚ scale‚ and a wooden flynt. These materials are used to help collect and test the Butane gas. Butane gas was used because it is ideal at standard temperature and pressure. Procedure: 1. Rinse bucket and fill three fourths full. 2. Rinse all glassware. 3. Place

This chapter discusses the importance of weight management. The most affective way of managing your weight is by controlling the amount of calories that your body consumes with the amount of exercise that you get in your daily activities. Currently about 66% of Americans are overweight. This number has nearly doubled since the year of 1980. There are two types of fats‚ subcutaneous fat‚ visceral fat. Subcutaneous fats are called lipids which affect your nerves‚ brain lungs‚ heart and

BTEC Chemistry – Titration experiment I – Standard Solution Prep Preparation of a standard solution of sodium carbonate Anhydrous sodium carbonate is a suitable chemical (primary standard) for the preparation of a standard solution. Standard Solutions are critical in chemistry because you need to have solutions with an EXACT known concentration and volume. Chemicals/Materials: solid sodium carbonate (Na2CO3) distilled water Apparatus: 250cm3 volumetric flask 250cm3 beaker Glass

Obesity is taking over America‚ resulting in people taking extreme measures to try and lose weight. Millions of people are overweight and obese and are at risk of major health problems. The more body fat and weight that a person has to carry on themselves‚ the more risks they have. In this day and age people want to lose weight as fast as possible either naturally or surgically. Your weight is the result of many different factors. Some of these factors include family history and genetics‚ your

vibration frequency and bond length for H35Cl‚ H37Cl‚ D35Cl‚ and D37Cl and to compare the isotope effects to theoretically predicted values. Introduction Vibration spectroscopy is one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the absorption of infra-red light by green house gasses‚ which include CO2‚ H2O‚ and CH4

Lifting weights has been my de-stressor for a while now‚ even if I did not label it as that before this assignment. It has proven to be effective at keeping me as stress free as can be expected as well. With me taking the two hardest accounting classes this semester I have needed to not get in the over-stressed zone that makes me too worried to complete my work I need to do for each of those classes. The shear amount of work I have to do for each of my accounting classes which cause more stress then

t-Pentyl Chloride is a compound that is created through an SN1 nucleophilic substitution reaction in addition with Hydrogen Chloride in order to isolate the product. A variety of procedural techniques were utilized during the experiment including extraction‚ washing liquids‚ drying liquids‚ gravity filtration‚ and simple distillation. When a single solute or compound is transferred between two different solutes‚ it is known as extraction. Another technique that was utilized was washing‚ in which

Largest Sty in the world Majyd Aziz The largest sty in the world is ironically in Pakistan. In fact in Karachi‚ known as SITE Karachi. It is an industrial estate with 3000 plus industries‚ shops and warehouses and managed by a quasi-government organization called SITE Ltd while the “tenants” are represented by SITE Association of Industry. But why would this estate that contributes 28% to the nation’s Treasury be dubbed as a ‘sty’? The answer lies in taking a tour of this 4500-acre estate. I once
