Argumentative Fallacies "Writers of argumentative essays must appear logical or their readers will reject their point of view. Here is a short list of some of the most common logical fallacies--that is‚ errors in reasoning. Check your rough drafts carefully to avoid these problems. "Students sometimes ask‚ ’If a logical fallacy works‚ why not use it? Isn’t all fair in love‚ war‚ and argumentative essays?’ The honest answer is maybe. It’s quite true that speakers and writers do use faulty logic

Solubility Product Determination Purpose • To determine the solubility product constant‚ Ksp‚ of an ionic compound. Introduction The solubility product constant‚ Ksp‚ is a particular type of equilibrium constant. The equilibrium is formed when an ionic solid dissolves in water to form a saturated solution. The equilibrium exists between the aqueous ions and the undissolved solid. A saturated solution contains the maximum concentration of ions of the substance that can dissolve at

10-fold dilution of this ionic iron solution and 5 drops of concentrated HNO3 was made. This solution served as the source of ionic Iron for the remainder of the lab and was labeled “stock ionic Iron solution.” Next‚ a 50-mL aqueous ionic Iron and FerroZine® complex solution was prepared by adding 5.00mL stock ionic Iron‚ 3-mL of acetic acid buffer‚ 2-mL of 5% hydroxylamine hydrochloride‚ allowing five minutes for hydroxylamine to reduce Fe3+ to Fe2+‚ adding 2.5-mL of 0.01 M FerroZine® solution‚ and

EXPERIMENT 3: INTRODUCTION TO TITRATION – DETERMINATION OF THE MOLARITY AND CONCENTRATION OF SULPHURIC ACID BY TITRATION WITH A STANDARD SOLUTION OF SODIUM HYDROXIDE INTRODUCTION Reaction of acid and base is one of the most common reaction in chemistry. This reaction is also widely known as neutralization. In this experiment‚ we used titration technique which involves accurately measuring the volume of a solution required to react with another reagent. An indicator must be used to determine the

Jahzeel Morales Jessa Arellano September 19‚ 2014 Period 4 Lab #1: Density Determinations for Solutions Theory: The density of a sample of matter is very useful when trying to find the identity of an unknown substance. The units of density are quoted in (g/mL) for liquid samples of matter. For that reason if the volume is known of a liquid‚ determining its density is easily determined by weighing it accurately. Density can also be used as a tool for finding the concentration of solutions
