concept of a conjugate acid-base pair. Using equilibrium law and K‚ explain the relationship between the strength of an acid/base and its conjugate. Conjugate Acid-Base Pair: Conjugate acids and bases were presented by Bronsted-Lowry‚ who was a chemist who proposed the theory that both acids and bases required the transfer of a proton in order for there to be a reaction. An acid will donate a proton (proton donor)‚ forming what is considered to be a conjugate base. When the base accepts a proton (proton

Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

Question In general‚ which is worse – acid or base conditions? Answers and Discussion Obviously a balance is required. The neutral pH is 7.0‚ however the natural pH of sea water is typically around 8.2 and that of fresh water is typically around 6.5. The answer to the question depends very much on whether or not we are discussing the environment or human health. Human Health: Our skin is slightly acidic (pH 5 to 5.5) and we can withstand low pH values quite readily. If we ingest or touch water which

Acid Base Titration Purpose: The purpose is to calculate the molarity of a NaOH solution by titrating the base with 5mL of standard HCl solution in each trial. By adding the base with unknown molarity to the acid with 0.10M the molarity of NaOH can be calculated. The base‚ NaOH‚ helps bring the pH of the acid‚ HCl‚ closer to seven‚ which neutralizes it. When using the buret the amount of NaOH used is able to be determined. Then by writing a balanced chemical equation and using the titration

Introduction and Theory: A two dimensional object is a figure that has both width and height. Today in physics a two dimensional lab was done to decide the distance of an ice cream cone shooter. To do this‚ the formula (d=Ví t + (1/2) at^2) has to be implemented. I decided to make my Y equal to one meter‚ so my calculations would be easy to get. I knew my acceleration for Y was -9.8‚ the velocity initial for Y was zero‚ and the time it will take for the ice cream to reach zero is .452. For X I know

when was the pH value outside of the normal range‚ and what acid/base imbalance did this pH value indicate? The pH level was not within the normal range for human body. The pH level was outside of the normal range after 20 seconds‚ pH level above 7.45. The pH value indicate state of alkalosis. 7. Did the PCO2 level change during the curse of this run? If so‚ how? PCO2 level fluctuate from 19.7 to 40. 8. If you observed an acid/base imbalance during this run‚ how would you expect to renal system

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
