INTRODUCTION Potassium permanganate KMn is a strong oxidizing agent which reacts with reducing agent ethanedioate ion to give and C + 2 Mn+ 16 2+8+10 Sodium hydroxide (NaOH) reacts with acid to give water . the reaction is… View Article

Analysis of two Commercial Brands of Bleaching Solution

Objective To determine the concentrations of the active ingredients in 2 commercial bleaches. Introduction Sodium hypochlorite is usually found in bleaching solutions. It is the active ingredient of bleaching solutions. It bleaches by oxidation. When it is added to dye, the following reaction occurs: ClO- + dye —————-> Cl- + (dye + O) If the… View Article

Determination of Ksp of Copper(II) Iodate by E.M.F. Measurement

Introduction: Copper(II) iodate(V) ionizes weakly in water: Cu(IO3)2 + aq Cu2+(aq) + 2IO3-(aq) For a saturated solution of copper(II) iodate(V), concentration of IO3- ions doubles that of the Cu2+ (aq) ions, and Ksp of Cu(IO3)2(s) can be calculated by determining the concentration of Cu2+(aq) ion of a saturated Cu(IO3)2(aq). The e.m.f. of a galvanic cell… View Article

Potato Osmolarity Lab

Purpose: The purpose of the lab is to discover the osmolarity of the potato tissue. Background Information: Osmolarity is a concept similar to concentration, except it is the total number of solute particles per liter. In this lab we can show osmolarity by using sucrose solutions and potato ores. This experiment displays hypertonic, hypotonic and… View Article

Molar Mass of a Solid

Abstract: The purpose of this experiment is to determine the molar mass of an unknown solid. The freezing point of a solvent (Cyclohexane) was determined, and compare to the freezing point of Cyclohexane with the addition of two different concentration of unknown solid. The pure substance of Cyclohexane has defined physical properties. However, when a… View Article

Conventional wisdom indicates

Many books on the market discuss the differing nature of the sexes. Conventional wisdom indicates that a man asked how to get someplace that he will give directions laced with compass points, tenths of miles, and street names. The same conventional wisdom indicates that a woman, asked for the same information, will give directions that… View Article

Determination of Copper by Complexation

ABSTRACT To determine the concentration of copper in an unknown solution by using copper complexation, solvent extraction and spectrophotometry. Standards are used to create a calibration curve and the unknown concentration of copper is then calculated by using the linear equation from the calibration curve. The concentration of copper in the unknown solution 201 was… View Article

Determining the Osmolarity of a Potato

Abstract Students in Biology find it difficult to understand the concept of tonicity and osmolarity in a real time situation. In this investigation, several concentrations of sucrose were used to determine the osmolarity of a potato. It was found that the concentration of sucrose was close to 3.6 in the potato used showing that it… View Article

Food Dye Lab

Abstract: The purpose of this lab was to determine the food dyes present in a selected beverage, their concentration, and then replicate the solution within a 20% margin of error. The beverage we chose was Gatorade Frost Riptide Rush. A spectrometer was used to determine which food dyes were present in the sampled beverage, red… View Article

Beer’s Law Lab Report

Abstract: The Beer’s law lab was conducted to determine the optimal wavelength of Co(NO3)2·6H2O with the use of spectrometry. The results determined that the optimal wavelength to study the absorbance of this salt was 500nm. It also demonstrated how transmittance of light and absorbance of light are inversely proportional because absorbance is calculated by multiplying… View Article
