Investigation - Solution Colour and Ion Concentration Aim: To investigate whether solution colour can be used to reliably determine the concentration of coloured ions in a solution. Hypothesis: the concentration of permanganate ions in the solution is inversely proportional to the percentage transmission of light through the solution. Dependent variable: concentration of permanganate ions. Independent variable: percentage transmission of light through the solution. Equipment: 20 ml

2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with

I. Title Identification of an Unknown Plasmid In this experiment‚ we determined the phenotypic capability of an unknown plasmid along with its size. With the use of gel electrophoresis‚ we analyzed the gel photograph by using a standard DNA marker‚ Lambda HindIII‚ and came to a conclusion based on our results. II. Abstract Two experiments were done to identify an unknown plasmid. The success of these experiments came from the use of modern day technology involving gel electrophoresis

IDENTIFICATION OF AMINO ACIDS BY MEANS OF TITRATION CURVE ABSTRACT The aim of the experiment was to identify an unknown amino acid through acid-base titrations which was prepared in water to form an acidic solution. Each group prepared unknown amino acid hydrochloride. The pre-prepared basic solution was slowly added to the amino acid solution and pH change was closely observed using the pH meter. During these titrations the amino acid converted from cation to zwitterion to anion; zwitterion

The identification of Bamboo using various PCR and Sequencing Techniques Abstract Often the incorrect bamboo species is sold to unsuspecting customers at shops. This can have a disastrous effect on their garden. Three separate and unknown Bamboo leaf samples were taken and were required to be distinguished genetically from one another. Using ITS-PCR DNA amplification techniques‚ the ITS region DNA was amplified and used in PCR-RFLP and RAPD PCR in order to determine the genetic identity of each
