Acids and Bases Mirza Hasan Mammadov Acids and bases are really important in our daily day life. So let’s start with telling the definitions of them. Starting with acids‚ they are a substance which dissociates in water in order to produce one or more hydrogen ions. Also we can write H+ instead of hydrogen ion. Bases have the same definition‚ although the difference is that it firm hydroxide ions instead of hydrogen ions. We can write OH- instead of hydroxide ion. All alkali is bases but not

Measuring the Viscosity of Motor Oil ME331 Laboratory Assignment #1 Prepared for: Prof. Sangeorzan Submitted by: Abstract An experiment was conducted to model the effect of temperature on the viscosity of motor oil and compare the results to commercial values established by the Society of Automotive Engineers (SAE) for SAE 30‚ SAE 40 and SAE 5W30. The viscosity of the oil sample at eight temperatures between 20 °C and 55 °C was determined using a rotary Brookfield DV-II+ viscometer

Change can be seen as a form of transformation or conversion. A form of change can be seen in “Victory Lap” by George Saunders‚ a short story written in such a way that the events that are enrolling throughout the story are being processed and told through the minds of three main characters. Having the perspective of each character allows us‚ the readers to get a much greater understanding about them and to make a better character analysis. Having said that‚ this story is simply about a girl‚ Alison

Viscosity Lab Report. CITY UNIVERITY LONDON SCHOOL OF ENGINEERING AND MATHEMATICAL SCIENCES 1. Abstract. In this experiment the viscosity of pure glycerol and a glycerol – water mixture are measured. At the end of the test it is apparent that glycerol is a near perfect Newtonian fluid and that it is more viscous than water. We also can appreciate how viscosity varies within a given temperature range. 2. Introduction. The purpose of this experiment was to find the viscosity of

2:05 P.M. Purpose: The purpose of the experiment is to measure the densities of liquids. Specifically‚ the two liquids that were used and measured in the research were deionized water (H2O) and alcohol (C2H5OH). Methods: Density is an intensive quantity that cannot be visually identified. Therefore‚ the most straightforward approach to this problem was to record the measurements of mass and volume. For volume of each liquid‚ the instruments used were a 50ml burette‚ a 50ml graduated cylinder and a 10ml

of this lab is to identify the physical and chemical properties of four liquids: acetone‚ vinegar‚ hydrogen peroxide‚ and oil. By using our knowledge about the four liquids we needed to identify the components of an unknown mixture. Theoretical Background The liquids commonly found around the house such as acetone‚ vinegar‚ hydrogen peroxide‚ and oil was tested to identify the physical and chemical properties of these liquids. Acetone usually used as nail polish remover dissolves plastic. Vinegar

It was determined that the 5% isopropanol will remove the Red 40 dye from the stationary phase. The 28% isopropanol will remove the Blue 1 dye from the stationary phase. The more

ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple
